X10SCHED(5) File Formats Manual X10SCHED(5) NAME x10sched - layout of the x10.sched file for the X-10 CM11A serial inter- face DESCRIPTION heyu supports uploading a schedule of events to your CM11A interface. The schedule file (by default named "x10.sched") allows you to specify when you want X10 commands to be sent to X10 modules throughout your home. It also allows you to translate some X10 codes to other codes. More on that below. The X-10 CM11A connects to a computer with an RS232 interface. It can store about 128 events; each event can do things like turn on, turn off, or dim up to sixteen X10 modules. The CM11A box has a battery backed clock which the computer can read. The event data is stored in EEPROM memory. After a schedule is uploaded, the CM11A can be disconnected from the com- puter and even plugged in elsewhere in the house if desired. There are three important concepts used in the x10sched file. They are timers, triggers and macros. They all work together, in fact, the timers and triggers execute macros. The TIMER determines the date and time that a macro will be executed. Once a minute the CM11A looks at its internal table (frequently referred to as the EEPROM) to see if it's time to do anything. Timers can be restricted to certain days of the week or ranges of dates, or both. The TRIGGER represents real time actions. When the CM11A sees a powerline signal it compares the command with its table of triggers (also known as "macro initiators") and executes the appropriate macro. Triggers can be used to cause many actions when one remote control button is pushed. The MACRO consists of a label, an optional delay and a list of commands. Each macro can have up to 255 commands. The delay can be from 0 to 240 minutes. Macro labels can be significant. They can remind you of what it is supposed to do or it can remind you what triggers it. The label turn_c5_on_now leaves nothing to be imagined. There is no command that will dump the contents of the CM11A EEPROM to the serial port. This makes it impossible to alter discrete events or macros unless the entire table is known. This means that we can't set the macros using another program (ActiveHome(TM), for instance) and then add a new macro from Heyu. The timers and macros are stored in a file, by default in the same direc- tory as the configuration file x10config. (See x10config(5)). The default file name for the schedule file is x10.sched. You can override the de- faults by specifying the filename in the configuration file "x10config" with the SCHEDULE_FILE directive. (It must be stored in the same directory as the configuration file.) You can also override the defaults by provid- ing a fully qualified pathname in the environment variable X10SCHED or with the "-s" command line switch. The macro upload function will not work without a schedule file. Comments and blank lines are allowed in the file to make it more readable. White space is normally ignored. FILE FORMAT Refer to the sample file (x10.sched.sample) that came with the source code to help in understanding this section. There is no prescribed order for timer, trigger, macro, and comment lines in the schedule file - they may be grouped by type or mixed, at the user's option. The following are case-sensitive: X10 commands; macro labels; labels for aliases, scenes, and usersyns as defined in the config file. Housecode letters are not case-sensitive, nor is the day-of-week mask or any of the keywords used in the schedule file, e.g. TIMER, timer, tiMer are all equivalent. commentAs of version 2.0, anything on a line following a pound sign (#) is treated as a comment and is ignored by Heyu. Note that for versions of Heyu earlier than 2.0, a pound sign anywhere other than as the first character on a line was treated as a normal character and NOT treated as beginning a comment. sectionAny line beginning with the keyword section is totally ignored by Heyu, just as if it were a comment line. It is provided to enable user-defined breakpoints for external programs or scripts which might be devised by the user to reorganize a schedule file, and where use of ordinary comment lines for this purpose might be con- fusing. blank Blank lines are skipped over. timer The timer line consists of 7 required items. They are: the literal string timer (which is not case-sensitive), a day of week mask, the begin and end date range, the start time, the stop time, the start macro and the stop macro. In addition to these, there are several timer options which can be appended to the line. The day of week mask (DOW) is a 7 character field. Each position represents a day of the week when the timer should work. A timer that should execute every day is represented by the string "smtwtfs". To deactivate a timer for any chosen day of the week, substitute a period '.' for the appropriate letter. For instance, to activate a timer for Monday, Thursday and Saturday, you'd use the following string: ".m..t.s" (without the quotes). The DOW mask is combined with the date when the CM11A checks to see if it should execute a timer. Both date and DOW must match for the timer to execute. The begin-end range is a pair of month and day dates separated by a hyphen '-' or by a colon ':'. The first date represents when to be- gin, and the second represents when to end. The range is inclusive. The order in which month and day appear in each date must agree with the order specified with config directive DATE_FORMAT (or its de- fault), for example with the default 'DATE_FORMAT YMD', the date range would be entered as mm/dd-mm/dd, whereas for 'DATE_FORMAT DMY' it would be entered as dd/mm-dd/mm. The separator between month and day may any of the separators which can optionally be specified with DATE_FORMAT, namely '/', '-', or '.'. It does not have to be the same one. A single date can be specified by using the same values for the be- gin and end dates. Older versions of Heyu required that the begin date be less than or equal to the end date. Beginning with version 2.0, Heyu will interpret a begin date later than the end date as meaning the date range wraps around at the end of the year into the beginning of the year (including the current year). Examples: You would use 01/01-12/31 to indicate a timer that should be run daily. The range 12/01-02/01 is equivalent to the two ranges 12/01-12/31 and 01/01-02/01 With DATE_FORMAT DMY, the above range could be specified as 01-12:01-02, 01.12-01.02, or 01/12-01/02 For a date range involving the last day of February, see the de- scription of the FEB_KLUGE directive in x10config(5). Beginning with Heyu version 2.0, the effective date range of an up- loaded schedule can be configured to span years. A schedule up- loaded at any time during the year can be configured to operate cor- rectly for a period of from 1 to 366 days beginning on the upload date. So for example, a schedule uploaded on September 1st can be configured to run correctly and continually through September 1st (or 2nd) of the following year. For more information, see the de- scriptions for the MODE and PROGRAM_DAYS directives in the x10con- fig(5) man file, in particular "HEYU" mode versus "COMPATIBLE" mode. Regardless of the above directives, the user would normally program the schedule for the entire year. (Envision the schedule as being repeated for each year, past, present, and future.) When compiling for upload, Heyu automatically selects whatever parts of it are to be used in accordance with those directives and adjusts dates and times for Leap Years and Daylight Saving Time as required. As a special case beginning with Heyu 2.0, the date range "mm/dd- mm/dd" may optionally be entirely replaced with the expression "ex- pire-dd", where dd represents the range of dd+1 days ending on the last day of validity of the uploaded schedule. Thus the CM11A can be programmed to execute some macro as a reminder to the user that the schedule will shortly need to be reloaded. Note that in COMPAT- IBLE mode, reloading the schedule before Jan 1st will not accomplish anything, as the exact same schedule will be loaded. The start and stop times are in hh:mm format (hour:minutes 24 hour clock) You don't have to use two digits, 1:5 will work just fine for 5 minutes after 1 AM. The start macro and stop macro will be executed when their respec- tive time is reached. Note that these are really unrelated and in- dependant timers, and that the start macro is not restricted to turning things on and that the stop macro does not have to control the same X10 modules as the start macro. Either the start or stop macro can be the macro named "null" which is a dummy macro - it's never executed and thus does nothing. The macros referenced in the timer must be defined somewhere in the file. The schedule upload will abort if a macro is missing or mis- typed. (A warning will be issued if a macro is not referenced by any timer or trigger.) With versions of Heyu prior to 2.0, times for events had to be pro- grammed separately for dates when Standard Time and Daylight Time were in effect. Beginning with version 2.0, the user programs times for all events in legal (i.e., wall clock) time, and Heyu makes the necessary internal adjustment for the changeovers from Daylight -> Standard and vice-versa. The CM11A clock is maintained on Standard Time year around, transparent to the user. Also new with version 2.0 is the ability to directly specify times relative to Dawn and Dusk. (A separate program was supplied with earlier versions to do this.) Instead of the time expressed as "hh:mm", one can now use the format "dawn+mm" or "dawn-mm" or "dusk+mm" or "dusk-mm" (or just "dawn" or "dusk"). Heyu calculates the times of Dawn and/or Dusk and makes the substitution. The "mm" represents the number of minutes before or after Dawn/Dusk when the macro will be executed. "mm" can have any value, _except_ that the resulting time after resolving the times of Dawn/Dusk must fall within the range 00:00 to 23:59 or Heyu will quit with an error mes- sage. Dawn and Dusk are defined by default to be synonymous with sunrise and sunset. However this definition may be _globally_ changed to one or another of the standard twilight times, or to a user speci- fied Sun position, with the configuration file directive DAWN- DUSK_DEF. See man page x10config(5). When Heyu processes Dawn or Dusk related events, it subdivides the programmed date range into a number of unequal-length subintervals, each of which is assigned a constant time approximating the time of Dawn or Dusk over the subinterval. The number and lengths of these subintervals are chosen by an iterative procedure which minimizes the deviation from actual Dawn/Dusk times subject to the constraint of available EEPROM memory in the CM11A. (As a result, if Dawn and/or Dusk related event times are programmed, the amount of free EEPROM memory displayed will generally be pretty small. If more timers are added to the schedule they'll fit - within limits of course - but the deviation in the Dawn/Dusk times will be higher.) The Dawn or Dusk "error" reported by Heyu is the difference in min- utes between the maximum and minimum times of daily Dawn or Dusk over the above-mentioned subinterval. Whether this error in the constant time approximation on any particular day is plus or minus or mixed is determined by the DAWN_OPTION or DUSK_OPTION configura- tion directive. Heyu requires that every day have a Dawn and a Dusk, which is not the case in polar latitudes when the sun may be above or below the horizon all day, or when Dawn or Dusk is shifted into the previous or following day. To compensate, Heyu uses a ficticious Dawn and/or Dusk at 00:01 or 23:58 hours Standard Time (not necessarily repectively) as the situ- ation dictates. So for example in polar mid-summer, Heyu will rep- resent the day as occurring between 00:01 and 23:58, while in polar mid-winter, the night will be considered to occur between those times. To activate the so-called "security" feature of the CM11A, simply append the letter 'S' to the programmed start or stop time in ques- tion. "12:00s", "dawn+5s", "duskS" are valid examples of this. The time of the event will then vary each day by some random amount within +/- 30 minutes of the programmed time. Note that the CM11A itself actually applies a variation of between +0 and +60 minutes to the programmed time. Heyu subtracts 30 minutes from the programmed event time to get the +/- 30 minute variation. Heyu has to use a few tricks with the security feature when clock times around midnight are programmed, in particular when the pro- grammed time is between 22:59 and 01:30 (assuming Daylight Time is in effect at some time during the year in your locality), since the CM11A must be allowed to add a random time between 0 and 60 minutes at any time of the year without exceeding 23:59. To get around this, Heyu changes the programmed event time for the timer to 22:59 and creates an appropriately delayed macro. But this solution has its own problem, namely that if a delayed macro does not execute until the following day, it will not be exe- cuted at all on the day the schedule is uploaded. To get around this, Heyu uses a non-delayed macro and creates a new one-day-only timer event with its own +/- 30 minute randomly generated variation around the user's original programmed time. In order to test the operation of a schedule without having to wait around all day, Heyu version 2.0 will acccept the construct "now" or "now+NN" (with NN in minutes) in place of a start time and/or stop time in a timer. It will then substitute the current system time rounded up to the next whole minute, with a minimum of 15 seconds allowed for uploading the schedule. NN must be >= zero, otherwise the only restriction is that the resolved value of "now+NN" must not exceed 23:59. The security feature may not be used with the "now+NN" construct. Note that the date range and DOW mask must in- clude today if the macro is actually expected to be executed today. Example: timer smtwtfs 01/01-12/31 now now+2 lights_on lights_off Beginning with Heyu version 2.0, the reserved macro label "null" may be used as a "do-nothing" place holder in a timer, when neither of the timer concepts start or stop seem logically appropriate. (The null macro may be used liberally as required - it will take up no more space in the CM11A's EEPROM memory than if the user manually rearranged timer start and stop events solely to have something to "fill in the blank".) timer options There are four timer options which can be used to restrict the exe- cution of a timer only to days when the actual times of Dawn or Dusk during the year are less than (LT) or greater than (GT) the time specified with the option. The option keyword and time are appended to the end of the normal timer line. DAWNLT hh:mm - Execute only on days when Dawn occurs before hh:mm DAWNGT hh:mm - Execute only on days when Dawn occurs after hh:mm DUSKLT hh:mm - Execute only on days when Dusk occurs before hh:mm DUSKGT hh:mm - Execute only on days when Dusk occurs after hh:mm where hh:mm is expressed as legal (i.e. wall-clock) time. Example: timer smtwtfs 01/01-12/31 dusk 21:00 light_on light_off DUSKLT 21:00 This would result in the light being turned ON at dusk, OFF at 9:00 PM, but only on days when Dusk occurs earlier than 9:00 PM. Thus in extreme latitudes when Dusk might occur later than 9:00 PM during the summer months, the situation is avoided where the light is turned ON at Dusk and remains ON all night and all the next day un- til 9:00 PM. The timer options are not restricted to timers which involve Dawn or Dusk times. The above timer could just as well have been programmed as two separate timers: timer smtwtfs 01/01-12/31 dusk 00:00 light_on null DUSKLT 21:00 timer smtwtfs 01/01-12/31 21:00 00:00 light_off null DUSKLT 21:00 The time argument for the option does not have to be the same as the execution time of the timer. In the above example it might seems silly to have the light come ON for only a few minutes on days when Dusk started to approach 9:00 PM, so one could use DUSKLT 20:50 to ignore the days when the light might otherwise be ON for less than 10 minutes. More than one timer option can be used with a timer - all four in fact if deemed appropriate. Just string them together at the end of the timer line. The string ... DUSKGT 19:00 DUSKLT 21:00 would re- sult in the timer being restricted to execute only on days when Dusk occurs between 7:00 PM and 9:00 PM. Please note that the CM11A interface has no capability for condi- tional logic - Heyu merely compares the option time argument with the calculated Dawn or Dusk time for each day of the year and breaks up the date interval into multiple intervals. triggerThe trigger line consists of only 4 items. They are: the literal string trigger, the trigger unit, the command and the macro. The trigger unit is a combination of house code (a letter from a-p) and a unit number (from 1 to 16). An example is d12. The command will be either the word on or the word off. The CM11A will not trigger on any other type of X10 signal. The macro refers to a macro that will be executed. The macro must be defined somewhere in the file. macro The macro line consists of 3 or 4 items. They are: the literal string macro, the label, an optional delay, and a semicolon-sepa- rated list of one or more commands or scenes. The label is plain text of up to 32 characters which must be con- tiguous, and must be of printable characters. It must not begin with the characters '+', '-' or '_', and it must not contain the '$' character. The label is used by the timers and triggers to find the correct macro. When Heyu uploads a schedule, it write the macro names and EEPROM memory locations in file "x10macroxref" in the Heyu base directory, i.e., the directory where the configuration file is located. This file is used by the Heyu monitor to translate macro memory location to readable macro names as they are executed, so should not be deleted. The delay can be from 0 to 240 minutes long. It is represented by a simple cardinal number; no fractions, signs or decimals. However see the section "Problems with delayed macros" below. The Commands can be of several types; on, off, dim or bright being the most commonly used. The on and off commands have one argument, that being the address of the modules to be controlled. The address can be in the format of house code (hc) followed immediately by the unit number or range of unit numbers. The following are valid: d1 d1,2,3,9 d1-4,6 config A limited subset of configuration directives may appear in the schedule file when preceded by the word 'config', and will override the values of those same directives in the configuration file (or their default values). This feature is intended for use if you up- load schedules requiring different configurations on a frequent ba- sis, so you don't have to keep changing the configuration file every time. For most users however there's less chance of confusion by relying only on the directives as specified in the configuration file. The subset of directives includes only those which directly influ- ence how Heyu processes the timers, triggers, and macros to create the uploaded EEPROM image, to wit: MODE, PROGRAM_DAYS, LATITUDE, LONGITUDE, COMBINE_EVENTS, COMPRESS_MACROS, DAWNDUSK_DEF, DAWN_OP- TION, DUSK_OPTION, MIN_DAWN, MAX_DAWN, MIN_DUSK, MAX_DUSK, ASIF_DATE, ASIF_TIME, DATE_FORMAT, WRITE_CHECK_FILES, REPL_DE- LAYED_MACROS, FEB_KLUGE, RESOLVE_OVERLAP. See x10config(5) if nec- essary for an explanation of these directives. Heyu will quit with an error message if directives other than these are specified in the schedule file. Configuration directive lines in the schedule file always apply to the schedule as a whole regardless of where they appear in the file. It's good practise however to put them all at the beginning of the file so you won't overlook them later on and get confused. Example: config program_days 90 COMMANDS In addition to the on, off, dim, and bright commands, Heyu version 2 adds others which can be used for uploadable macros in schedules, including Ex- tended commands for modules like the X-10 LM14A 2-way lamp module. Run 'heyu help' for a complete list of commands implemented in the current ver- sion of Heyu. All the native X10 commands _except_ the Preset command may be used for uploaded macros. (The command 'mpreset' implements the very limited support for Preset in uploaded macros provided by the CM11A firmware.) Heyu version 2 includes built-in synonyms for many of the commonly used commands. Run 'heyu syn' to see these synonyms. Heyu version 2 also includes the ability for users to define their own syn- onyms ("usersyns") and/or compound commands ("scenes") in the configuration file, and use them in macros. X10 commands are generally transmitted over the power line in two "chunks", a series of address bytes, one for each unit, followed by one or more func- tion bytes. Both the address byte and the function byte reference the housecode (except for the 'preset' command, which has a peculiar function byte format). For some commands, the unit information contained in the address byte is superfluous and the address byte will normally be omitted. Examples of commands in this category include the "all" commands like 'lightson', and 'alloff', the 'hail' command, and any of the Extended commands (which in- clude the unit code within the function structure). No unit codes need be appended to the housecode for the "all" commands, e.g., lightson A alloff C are sufficient. If a unit is specified with the housecode, it will nor- mally be ignored. However if for some reason it is desireable for the com- mand to be issued along with an address byte, prefix the housecode with a '+' sign and add the unit string suffix, e.g., lightson +A4 An address byte is not normally sent with the Extended Code commands like 'xpreset' even though the unit must be specified. But again, prefixing the Housecode|Units with a '+' sign will instruct Heyu to include an address byte in the transmission. For the opposite effect, i.e. to suppress transmission of the address byte for any command, prefix the Housecode|Units with a '-' sign and omit the units. E.g., on -A A few commands warrant additional description: xfunc <T/F> HU <xx> - general extended command. The 'xfunc' command will transmit any arbitrary extended function <T/F> and data byte <xx>, where both are assumed to be hexadecimal bytes (0-0xff). Example: 0x31 is the function code for the extended preset command, and the following commands for setting the extended preset level for module c3 to level 26 (decimal) are equivalent: xpreset c3 26 xfunc 31 c3 1a The extended command code functions are described in X-10's document xtd- code.pdf (a replacement for the older XTC798.DOC) which is available for download from their website. The only extended code Types known to be ap- plicable to existing modules are the Type 3 for extended code lighting and appliance modules and Type 0 for the Marmitek SW10 Shutter controller. Macro commands can be strung together by separating them with a semicolon ';'. This allows one macro to affect several devices. Consider the com- mands needed to turn on the TV (d1) turn off the stereo (d3) and dim the 4 lights in the living room by half( c1, c2, c3 and c4 dim 11). This macro command string would do it. on d1; off d3; dim c1-4 11. As of Heyu version 2, macros can include scenes defined in the user's con- figuration file as if they were standard Heyu commands. Macros can also reference aliases defined in the configuration file in place of the Housec- ode|Units parameter. EXAMPLES In this timer, the macro c5on will be executed once a day at 2:58 PM. The macro c5off will execute at 2:59 PM. The timer is active every day of the week from 2/1 through 12/12. timer smtwtfs 02/01-12/12 14:58 14:59 c5on c5off The next one only runs on Dec 11, and then only if it falls on a Friday. timer .....f. 12/11-12/11 23:34 23:35 d6off d6off This timer sounds a chime (perhaps a Universal Module UM-506) every day at Noon, legal (wall clock) time, Monday through Friday, regardless of whether Standard or Daylight Time is in effect (Heyu ver 2.0 and later): timer .mtwtf. 01/01-12/31 12:00 00:00 lunch_chime null This one sounds a chime at 7 AM and 7 PM 3 days in a row before the expi- ration date and on the final date itself (a total of 4 days) to remind the user that the uploaded schedule will shortly become invalid and need to be reloaded. (Heyu ver 2.0 and later only): timer smtwtfs expire-3 07:00 19:00 chime chime The following two timers turn on an inside hall light 30 minutes before Dusk, dim it after 11 PM, and turn it off 15 minutes after Dawn (Heyu ver 2.0 and later): timer smtwtfs 01/01-12/31 dusk-30 23:00 hall_on hall_dim timer smtwtfs 01/01-12/31 dawn+15 00:00 hall_off null The following timer operates decorative lighting between Dusk and 10 PM during the holiday season without quitting on Jan 1st during non-leap years (Heyu version 2.0 and later): timer smtwtfs 12/15-01/02 dusk 22:00 xmas_on xmas_off This trigger runs macro c5off when 'c1 off' is received. The net effect would be that the device with the code c1 will be turned off AND whatever the macro c5off directs will be done too. trigger c1 off c5off In the following, E4 is a dusk sensor (MS13A) outside. It turns on the living room lamps (via the livinroom_on macro), but it does not turn them off. I use a timer to do that long before midnight. If I waited for the MS13A they'd turn off at dawn even if I'm reading my paper then. trigger E4 on livinroom_on This next macro is labeled c5off. It waits 5 minutes, then turns off d6 and d7 and turns on e2 macro c5off 5 off d6,7; on e2 And this macro includes dimming. macro c5on 0 on d7; dim d7 8 Since the delay is optional, the above can also be written as: macro c5on on d7; dim d7 8 Multiple Transmissions If the Multiple Transmissions box is checked for a timer in X10's Active- Home software, the timer is duplicated with the same macros but with the execution time set 1 minute later. This is simple enough to do manually (and with more flexibility) in the schedule file that no attempt has been made to automate this feature in Heyu. Problems with delayed macros. If a new schedule is uploaded between the time a timer or trigger is acti- vated and the time a delayed macro is executed, the macro will never be ex- ecuted because pending delayed macros are purged when a schedule is loaded. This is the nature of the hardware and is unavoidable. It should never be necessary for the user to program a delayed macro for a timer, and if Heyu finds one it by default attempts to adjust to this situation by creating a non-delayed macro and increasing the time of the timer to compensate. To change Heyu's behavior, see the REPL_DELAYED_MACROS directive in x10con- fig(5). (If the same macro is associated with a trigger, the original de- layed macro is uploaded for the trigger in addition to the new macro for the timer.)
