The cheapest route into smart heating, and it shows up fine in HA via the built-in Hive integration — though that integration is cloud-polling, so expect slight lag and a dependency on Hive's servers. The £79 kit is the wall-mounted thermostat plus a receiver that wires into your boiler's existing controls; that wiring is why Hive defaults to professional install at checkout, and DIY is only realistic if you're already comfortable inside a boiler's low-voltage terminals. Versus the full-size Hive Thermostat, you lose the physical display and dial — everything runs through the app — for the same core heating control. Single-zone only; multi-room needs the separate Multizone kit.
What can Home Assistant control on the Hive Thermostat Mini?
| Control | Type | What it does |
|---|---|---|
| Climate | Climate | hvac_mode heat/off, current and target temperature (0.5°C steps), plus preset_mode for schedule/manual/boost state. |
| Boost heating | Service/action | Overrides the schedule for a set duration (default 30 min) at +0.5°C over the current setpoint; must be called as an action, not toggled on the entity. |
| Mode | Sensor | Reports the active operating mode (schedule, manual, boost) as a separate diagnostic sensor from the climate entity's own state. |
| Battery | Sensor (%) | Battery percentage for the wall-mounted thermostat unit, which runs on AAA batteries independent of the mains-powered receiver. |
| Connectivity | Binary sensor | Cloud-reported online/offline status, useful for detecting the token-refresh dropouts the integration is known for. |
The climate entity exposes hvac_mode (heat/off), current and target temperature in 0.5°C steps, plus a Boost preset that runs a fixed 30-minute override at +0.5°C over the current setpoint via a dedicated action rather than a duration field on the entity itself. Setup mandates 2FA on the Hive account using the account owner's own credentials — secondary or shared logins are rejected outright by the config flow. Recurring community and GitHub reports describe token-refresh failures that throttle or fully lock out the Hive cloud API for the whole home network (not just Home Assistant) until the integration is removed and re-added, a pattern going back to 2022 that still surfaces after Hive-side auth changes. A workable automation despite the lag: fire the boost action for a set duration when a person/geofence entity flips to 'home' outside the scheduled heating window, since boost's fixed +0.5°C behaviour is predictable enough to pre-warm a room even though the resulting state update trails by a poll cycle.

Frequently asked questions
- Does the Hive Thermostat Mini work with Home Assistant locally?
- Partly. The Hive Thermostat Mini connects to Home Assistant through the manufacturer's cloud 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 Thermostat Mini use, and do I need a hub?
- The Hive Thermostat Mini 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 the manufacturer's cloud integration (hive).
- How much does the Hive Thermostat Mini cost in the UK?
- The lowest price we have listed for the Hive Thermostat Mini is £79 at Hive Home. Prices were last checked in September 2026 and change often, so confirm on the retailer's page before buying.
