Supported Functions
What the integration does — and does not — do for each OpenWebNet subsystem (WHO) and Home Assistant platform. Hardware and gateway models are listed in Hardware Compatibility; the wire-level conformance corpus is in the Protocol Conformance Matrix. Things that are deliberately not supported, and why, are in Known Limitations.

| Colour temperature (DALI DT8) |
✅ |
Dimension 14, 2000–6535 K; learned from the first colour frame. |
| HS / RGB colour |
✅ |
Learned from the first colour frame; modes accumulate, they never replace each other. |
| Hardware timer |
✅ |
myhome.turn_on_timed: the actuator switches off by itself. |
| Group / area / general commands from wall switches |
👁️ |
Frames are seen, but entities only update when the actuator reports its own status — see limitations. |
switch (WHO 1)
| Function |
Status |
Notes |
| On / off |
✅ |
Device class switch or outlet from myhome.yaml. |
| Hardware timer |
✅ |
myhome.turn_on_timed. |
cover (WHO 2)
| Function |
Status |
Notes |
| Open / close / stop |
✅ |
|
| Position (position-reporting actuators) |
✅ |
Requires advanced_shutter: true in myhome.yaml; it is not learned from the bus. |
| Position (timed actuators) |
✅ |
Virtual position from the travel time: travel_time in YAML, measured with myhome.calibrate_cover, or set by hand with myhome.set_cover_travel_time. |
| Tilt |
❌ |
Slat commands are parsed by OWNd but not exposed. |
| Echo suppression |
✅ |
The gateway's relay of our own command is not mistaken for a keypad press. |
climate (WHO 4)
| Function |
Status |
Notes |
| Current temperature |
✅ |
|
| Target temperature |
✅ |
Manual set-point. |
| HVAC modes |
✅ |
heat, cool, auto, off; heating / cooling support per zone from YAML. |
| Fan speed (3-speed fancoil) |
✅ |
fan: true. |
| Central unit modes |
✅ |
Central unit 3550 (#0) and 4695 (#0#1) as central: true zones; seasonal propagation. |
| Weekly programs / scenarios |

| Function |
Status |
Notes |
| Dry contacts (CEN+, WHO 25) |
✅ |

inverted: true. |
sensor (WHO 1 / 4 / 18)
| Function |
Status |
Notes |
| Instantaneous power (W) |
✅ |
Push-driven; myhome.start_sending_instant_power requests a burst of readings. |
| Energy total / today / month (Wh) |
✅ |
Today and month are disabled by default. |
| Temperature (zones and probes) |
✅ |
Zones are polled every 5 min; probes (WHERE ≥ 100) are push-driven and only polled when silent. |
| Illuminance (lux) |
✅ |
WHO 1 light sensors. |
| Humidity |
👁️ |
Shown as the climate entity's current_humidity when the zone reports it; no separate sensor. |
| Function |
Status |
Notes |
| Lock / unlock actuator |
✅ |
On every light, switch and cover device (EntityCategory.CONFIG). |
| Calibrate travel time |
✅ |
On every timed cover device, plus Calibrate all covers on the gateway device. |
| Function |
Status |
Notes |
| On / off, volume, mute, source 0–4 |
✅ |
Per zone / amplifier. |
| Streaming (play, pause, next, previous) |
✅ |
Only when decoders are mapped in the options flow: the zone becomes a Music Assistant / Spotify target and routes the matrix to a free decoder. |
| Media metadata |
👁️ |
Mirrored from the decoder while a stream is active. |
| Speaker groups |
❌ |
Use Home Assistant / Music Assistant grouping on the decoders. |
Device triggers (WHO 15 / 25)
| Trigger |
CEN |
CEN+ |
| Short press / short release |
✅ |
✅ |
| Long press / long release |
✅ |
✅ |
| Rotary dial clockwise / counter-clockwise, slow and fast |
✅ |
✅ |
Buttons 0–31 per device; every trigger carries the gateway MAC so multi-gateway plants do not cross-fire.
