Drayton Wiser Smart Thermostat Kit 1 (Combi Boiler)
The best-value route into room-by-room heating control if you have a combi boiler and no interest in a monthly fee. Buy it for the zoning and the OpenTherm modulation, not for a slick app.
Our editorial rating, not aggregated user reviews
The value pick, and the one that charges you nothing to keep using what you bought. Reviewers at Trusted Reviews and Expert Reviews land in the same place: scheduling is flexible, the hub supports OpenTherm so a compatible combi boiler can modulate rather than cycle, one system scales to 16 rooms and 63 devices as you add radiator valves, and there is no subscription for any of it. Two things keep it out of the 8s. The app is functional rather than good, and reviewers describe it getting cluttered once you add devices; there is no learning, so the schedule is only as good as the person who sets it. And the radiator valves, which are the reason to choose this system over a single smart stat, have no display at all, so the room temperature and target are visible only in the app. Owner reports of the hub dropping its connection and leaving no heating and no override are frequent enough to mention honestly. Good, and excellent for the money, but the app is a real limit for some households.
Pros
- No subscription for anything, including scheduling, geofencing-style away control and multi-room zoning
- OpenTherm support on the HubR, so a compatible combi boiler can modulate its output rather than fire flat out and stop
- One system covers up to 16 rooms and 63 Wiser devices, so you can start with the thermostat and add radiator valves a room at a time
- Radiator valves are noticeably cheaper than the competition, which is what makes whole-house zoning affordable here
- Works with Alexa, Google Assistant and IFTTT
Cons
- This kit is the single-channel version for combi boilers. A conventional or system boiler with a hot water cylinder needs the two-channel Kit 2 instead, which is a different product
- The radiator valves have no screen, so current and target temperature are only visible in the app
- No learning at all. The savings depend entirely on you setting a sensible schedule
- Reviewers find the app cluttered once several devices are added, and it is the only real interface the system has
- Owners report the hub losing its connection, which leaves no heating and no local override until it recovers
- Matter bridging arrived with the second-generation HubR. Check which hub generation your listing ships before relying on it
- Sold in the UK and Ireland only, and built around UK boiler and radiator conventions
