Depends on OpenWebNet-HA/MyHOME#650: MyHOME's copy of the OWNd edge tests (tests/test_message_edges.py) asserts the old auto reading for *4*13001*1## / *4*23001*1##, so this PR's downstream "MyHOME test suite" job (which runs MyHOME v2-phase1-architecture against this checkout, .github/workflows/myhome-conformance.yml:70-86) stays red until #650 is merged. OWNd's own checks are green.

Before: *4*13001*1## and *4*23001*1## were read as AUTO (both ranges sat in the generic-mode list next to 33xxx).

After: 13xxx reads as HEAT and 23xxx as COOL, and all three ranges expose the day count as holiday_days (*4*23001*1## → mode = cool, holiday_days = 1; *4*33004*#0## → auto, 4).

Evidence

Spec. p. 5 and p. 64, WHAT table: 13xxx = holiday days, heating mode; 23xxx = holiday days, conditioning mode; 33xxx = holiday days, generic mode; xxx = 1..255 days.

libqtdevices TS10_1_0_23. thermal_device.cpp:

 58: 	SUM_HOLIDAY = 23000,             // holiday operation (programma ferie)
 68: 	WIN_HOLIDAY = 13000,             // holiday operation (programma ferie)
258: 	case SUM_HOLIDAY:
259: 		values_list[DIM_PROGRAM] = program;
260: 		values_list[DIM_STATUS] = ST_HOLIDAY;
261: 		values_list[DIM_SEASON] = SE_SUMMER;
303: 	case WIN_HOLIDAY:
304: 		values_list[DIM_PROGRAM] = program;
305: 		values_list[DIM_STATUS] = ST_HOLIDAY;
306: 		values_list[DIM_SEASON] = SE_WINTER;

23xxx sets the summer season, 13xxx the winter season; the client never maps either to automatic.

Firmware. bt_termo, identical on MyHomeServer1, F454, F459, F461, F450 (results/termo*.tsv):

Frame	Reply	Bus body	Reading
*4*13004*#0##	NACK	none	monitor-only WHAT (Spec p. 64), not a command
*4*23004*#0##	NACK	none	same
*4*33002#3115*#0##	ACK	D1 00 03 02 C1 05 02 0E	holiday command: byte 7 = 02 days, byte 8 = program 15
*4*33005#3102*#0##	ACK	D1 00 03 02 C1 05 05 01	5 days, program 2

So the firmware carries the day count of the holiday WHATs as a real value (byte 7), and the heating / conditioning variants are status reports the central unit sends, which is what OWNd parses here.

How

OWNd/message/heating.py: 23001-23255 moves to the COOL range, 13001-13255 to the HEAT range, 33xxx stays AUTO; each sets holiday_days = mode % 1000. New holiday_days property. Tests: the two test_mode_auto_weekly_* cases in tests/test_message_edges.py encoded the old reading and are replaced by test_mode_holiday_*. pytest: 1239 passed, 1 skipped.

How to check. libqtdevices quotes are from tag TS10_1_0_23 of OpenWebNet-HA/libqtdevices (BTicino's 2010 touch-screen client, used only as a second client, not as the reference). Firmware rows are replays of the exact frame on the original gateway translator binaries (ARM, from the MyHomeServer1, F454, F459, F461 and F450 images) under QEMU on a fake SCS bus: ACK = *#*1##, NACK = *#*0##, the bus body is what the program put on the SCS bus (hex, without the A8 / checksum / A3 framing). Spec = Legrand/BTicino "Open Web Net Language, WHO = 4" v2.0.0 (2013-11-27). Raw logs, command lists, the harness and the report are in firmware_validation.zip (results/<program>[_<image>].tsv, results/*.cl / *.stub / *.mon, REPORT.md). The firmware images themselves are not included.

Split out of #86 so each change can be checked on its own; the eight slices (#87-#94) merge together in any order without conflicts, and the merged union passes 1285 tests with 100 % coverage of OWNd/message (checked locally on 2026-10-07 after the review rework of #94).

Superseded by #97, which carries this change verbatim together with the other WHO 4 heating fixes. Closing as agreed in OpenWebNet-HA/MyHOME#649.
