The UK enthusiast favourite: the HeatHub exposes a local API, and the actively maintained wiserHomeAssistantPlatform HACS integration (v3.4.x) gives cloud-free control of zones, TRVs and hot water. Best-value multi-room ecosystem if you don't mind installing one custom component. Kit 1 is the entry point, not the full system: a one-channel HeatHub plus a single wireless Room Thermostat, OpenTherm module and wall bracket — no radiator TRVs included, so out of the box it's whole-home control, not room-by-room zoning. At roughly £140-£165 it undercuts Hive's Active Heating (from £149) and sits close to tado's V3+ (from £129), but Wiser only pulls ahead on value once you add Radiator Thermostats at ~£45 each to build out zones, and unlike tado there's no ongoing subscription. Best fit: combi-boiler households planning to expand zone-by-zone, not anyone needing multi-room control on day one.
What can Home Assistant control on the Drayton Wiser Thermostat Kit 1?
| Control | Type | What it does |
|---|---|---|
| Room climate | Climate entity (per room) | Target temperature and mode, aggregating every TRV in that room |
| Hot water | Water heater entity | Separate on/off control for hot water, independent of room heating |
| Room sensors | Sensor (temp/humidity/battery) | Per-room diagnostics |
The asantaga/wiserHomeAssistantPlatform HACS integration adds a climate entity per zone/TRV plus temperature, humidity, battery and signal sensors, with hot water as its own water_heater (or climate, on v2 hubs) entity — separate from room heating. That split means you can automate hot water to fire 20 minutes ahead of the first zone's scheduled heat, against the HeatHub's local API rather than cloud polling. Requires HA 2025.5+; v2 hubs on firmware below 4.42.23 can't connect over HTTPS.

Frequently asked questions
- Does the Drayton Wiser Thermostat Kit 1 work with Home Assistant locally?
- Yes. The Drayton Wiser Thermostat Kit 1 is controlled locally in Home Assistant through a community integration installed through HACS (wiser), so it keeps working if your internet connection or the Drayton cloud goes down. Control and state updates stay on your own network.
- Which protocol does the Drayton Wiser Thermostat Kit 1 use, and do I need a hub?
- The Drayton Wiser Thermostat Kit 1 uses Wi-Fi and Zigbee. To pair it with Home Assistant you need no hub — it joins your Wi-Fi network directly; or a Zigbee coordinator (for example a SkyConnect/ZBT-1 or Sonoff dongle) attached to your Home Assistant host. Drayton's own hub is not required when you integrate through a community integration installed through HACS (wiser).
