I don’t think this is related to HomeKit. Afaik the central units are not fully supported. Pls read here: > [@\[BTicino/OpenWebNet\] New openHAB2 binding ready for testing](https://community.openhab.org/t/bticino-openwebnet-new-openhab2-binding-ready-for-testing/43377/1334): > > a basic support (no Central Unit) of WHO=4 is work in progress, but I have no target release yet: In any case it will be released as 3.1.0.M?, unfortunately 2.5.x cannot be improved with new features. And the binding documentation: > Thermo zones management and temperature sensors (probes). NOTE Central Units (4 or 99 zones) are not fully supported yet. See [Channels - Thermo](https://www.openhab.org/addons/bindings/openwebnet/#configuring-thermo) for more details. > **[OpenWebNet (BTicino/Legrand) - Bindings](https://www.openhab.org/addons/bindings/openwebnet/#configuring-thermo)** > > This binding integrates \*\*BTicino / Legrand\*\* \*\*MyHOME ® - BUS/SCS\*\* and \*\*MyHOME ® Radio - Zigbee\*\* wireless devices using the OpenWebNet protocol. For my understanding you need to change the setpoint in the central unit too (not only at the thermostat) or it will be overwritten with the old value from the central unit. --- _[View the full topic](https://community.openhab.org/t/unsupported-target-heating-cooling-state/126703)._
