The combi-boiler Hive kit bundles the thermostat with the newer Nano 3 Hub and is OpenTherm-capable, which is the main reason to pick it over an older Hive set. Home Assistant support is in core, but it is cloud polling through your Hive account, so no internet means no control. The account catch matters more than the hardware: only the account owner's login works and 2FA must be on. A retailer lists the 852108 kit as supporting up to 6 heating zones with extra thermostats.
What can Home Assistant control on the Hive Smart Thermostat for Combi Boilers with Nano 3 Hub (OpenTherm)?
| Control | Type | What it does |
|---|---|---|
| Climate | Climate | Heating mode and target temperature with a Boost preset (30 minutes, 0.5 degrees above current). |
| Water heater | Water heater | Hot water mode, where the system has hot water control. |
| Boost actions | Action | Boost heating and boost hot water on/off. |
Core Hive integration (Settings > Devices & Services > Hive), cloud polling at 5 minutes by default with a 30-second floor. It uses your Hive website login, which must be the account owner with 2FA enabled; a secondary or shared user will not work. Heating shows as a climate entity with a 30-minute boost preset, hot water as a water heater, and there are boost actions. Removing the integration deregisters the Home Assistant device from your Hive account, so re-adding means registering again. The HA docs do not mention the Nano 3 by name or OpenTherm data, so do not expect boiler modulation values as sensors.

Frequently asked questions
- Does the Hive Smart Thermostat for Combi Boilers with Nano 3 Hub (OpenTherm) work with Home Assistant locally?
- Partly. The Hive Smart Thermostat for Combi Boilers with Nano 3 Hub (OpenTherm) connects to Home Assistant through a built-in Home Assistant core integration (Hive), which relies on the Hive cloud. It works in Home Assistant, but commands go via the internet and stop working during an outage of your connection or the Hive service.
- Which protocol does the Hive Smart Thermostat for Combi Boilers with Nano 3 Hub (OpenTherm) use, and do I need a hub?
- The Hive Smart Thermostat for Combi Boilers with Nano 3 Hub (OpenTherm) uses Zigbee. To pair it with Home Assistant you need a Zigbee coordinator (for example a SkyConnect/ZBT-1 or Sonoff dongle) attached to your Home Assistant host. Hive's own hub is not required when you integrate through a built-in Home Assistant core integration (Hive).
