Tools to control home heating

The problem, in plain words: “My gas central heating runs on a basic timer and heats the whole house all evening even when most rooms are empty, and I want a smart thermostat to heat only when and where needed within a £100–£150 budget.”

No tool in the catalog fully fits this yet.

You want a UK-compatible smart thermostat that avoids heating the whole house by scheduling and room-level control, within £100–£150.

Partly fits

RoomMindpartial · 72

It’s designed for Home Assistant per-room climate control with presence-aware and pause logic, which aligns with heating only occupied rooms.

Won’t cover: It requires Home Assistant and room-level climate setup rather than replacing a basic boiler timer for UK gas central heating by itself.

Climate Group Helperpartial · 64

It’s built to manage and synchronize multiple climate devices in Home Assistant, including schedule automation and presence/window-based control.

Won’t cover: It focuses on coordinating multiple Home Assistant climate devices rather than providing a standalone UK gas central heating smart thermostat replacement.

ThermoSmartpartial · 61

It targets heating control that adapts to a building’s thermal behavior and can improve over fixed schedules.

Won’t cover: It is a Home Assistant integration, so it doesn’t directly act as a UK gas central heating thermostat unless your system is supported there.

OTGatewaypartial · 55

It turns an OpenTherm-compatible boiler into something closer to smart thermostatic control, with remote/automation-friendly heating modes and sensor support.

Won’t cover: It only fits boilers and thermostats that support OpenTherm, so it may not work with your specific UK gas setup.
