Hive Hubless V4 Wireless Smart Heating Thermostat OpenTherm 852109
The Hive Hubless V4 Wireless Heating Smart Heating Thermostat (MPN 852109) is a battery-powered wireless smart thermostat that connects directly to your home Wi-Fi — no separate Hive Hub required. A compact touchscreen displays the current and target temperature, lets you adjust settings by hand, and the Hive app gives full remote control from any iOS or Android device. Voice control works out of the box with Amazon Alexa, Google Assistant and Apple HomeKit.
What sets the V4 apart is OpenTherm compatibility. Where older thermostats simply switch the boiler on and off, OpenTherm enables a digital dialogue between the thermostat and a compatible combi boiler — the boiler is told exactly how much heat is needed and modulates its output accordingly. This load compensation can reduce gas consumption and boiler wear, keeping the radiators closer to the target temperature with fewer on/off cycles. Works with most gas, LPG and oil boilers; the receiver is included and mounts near the boiler.
& Zigbee
Pairs directly with your home router over 2.4 GHz Wi-Fi using Zigbee to the receiver — no Hive Hub or bridge required. Setup is via the Hive app in minutes.
When connected to a compatible combi boiler, OpenTherm tells the boiler the exact water temperature needed — reducing gas consumption by up to 12%¹ and cutting unnecessary on/off cycling.
The Ready By feature learns how long your home takes to reach the target temperature and fires the boiler early so the house is warm at the beginning of each scheduled period — automatically.
Create daily heating schedules through the app or touchscreen, with up to 6 programmable slots per day. One-tap Boost overrides the schedule for up to 6 hours.
The Hive app detects when you leave home and sends a push notification if the heating is still on — one tap to turn it off from wherever you are.
Holiday Mode turns heating off for a defined period and restores the schedule automatically on your return date. Frost protection fires the boiler if the temperature drops below 7 °C.

¹ Up to 12% gas saving with OpenTherm modulation vs standard on/off relay control — Hive.
Do I need a Hive Hub?
No — the Hubless V4 (852109) connects directly to your home router via the receiver's built-in Wi-Fi. No Hive Hub, bridge or ethernet dongle is needed. The Hive app connects to the thermostat and receiver via the cloud.
Does my boiler support OpenTherm?
Most modern condensing combi boilers from Worcester Bosch, Vaillant, Viessmann, Ideal, Baxi and others support OpenTherm, but not all. Check the Hive boiler compatibility tool at hivehome.com/boiler-compatibility before ordering. If your boiler is not OpenTherm-compatible, the Hubless V4 still works — it just uses standard relay on/off control.
Can it control hot water?
No — the Hubless V4 (852109) is a heating-only thermostat. If you have a hot water cylinder and want to schedule both heating and hot water from one controller, choose the Hive V4 Heating & Hot Water Smart Thermostat (852112 or 852113) instead.
What does Geolocation do?
When your smartphone leaves a defined home area, the Hive app sends a push notification if the heating is still on — letting you turn it off remotely with one tap. It does not automatically turn the heating on or off; it only sends an alert so you decide what to do.
Can I control multiple zones?
Yes — up to six heating zones if you have an existing multizone heating system. Each zone needs its own Hive thermostat. All zones are managed from the same Hive app.
