Works with Home Assistant
Every device here has been checked against Home Assistant by us — how it integrates, whether it works locally without the manufacturer's cloud, and where to buy it in the UK. Pick a device type to see what we recommend.
Smart lighting
Every bulb, light strip and lamp here works with Home Assistant — most of them locally, with no vendor cloud in the loop. We've mixed Zigbee stalwarts like Philips Hue and Innr with newer Matter-over-Thread and local Wi-Fi options, and flagged which ones need a hub, which pair straight to a Zigbee dongle, and which just join your network. UK prices and B22/E27 fittings throughout.

Thermostats & heating
Smart thermostats and radiator valves that work with Home Assistant, verified against UK heating systems from combi boilers to S-plan zoned setups. UK smart heating is its own world — combi boilers, S-plan zones and TRVs on every radiator — and Home Assistant support varies wildly, from fully local Matter thermostats to cloud integrations that lag by a minute. Every thermostat and radiator valve here is verified against UK heating systems, with honest notes on which integrations are local, which poll a cloud, and what that means for your automations.

Smart plugs & energy
Smart plugs are the cheapest way into Home Assistant automation, and with energy monitoring they feed the Energy dashboard per-appliance. Everything here has a proper BS1363 UK plug (no EU-pin imports), verified Home Assistant support, and a note on whether the energy readings are accurate enough to trust. From £6 Matter plugs to CT-clamp meters for whole-home monitoring.

Sensors
Sensors are what make a smart home actually smart — motion, presence, door contact, temperature and leak detection are the triggers behind every good automation. This list leans local: Zigbee sensors that pair straight into Zigbee2MQTT or ZHA, Matter-over-Thread newcomers, and mmWave presence sensors that know you're still in the room when you sit still. All verified purchasable in the UK.

Cameras
The camera market splits cleanly in two: cameras Home Assistant can pull a live stream from locally (RTSP/ONVIF — no cloud, no subscription), and cameras locked to a vendor cloud that Home Assistant merely pokes at. We flag which is which on every card, because it's the single biggest thing that determines whether your camera is genuinely yours. UK pricing, indoor and outdoor picks, budget to premium.

Relays & dimmer modules
The invisible option: relay and dimmer modules hide behind your existing UK light switches and sockets, making dumb circuits smart while everything looks completely normal. This is Home Assistant's power-user territory — Shelly's local Wi-Fi modules and no-neutral Zigbee options dominate. Crucial UK caveat: many British back-boxes have no neutral wire, so we flag no-neutral support on every module.

Video doorbells
18 video doorbells compatible with Home Assistant, compared on local streaming vs subscription-locked cloud — see which ones dodge Ring and Nest's monthly fees. Pick a doorbell with local streaming and you get press events, person detection and recorded video with no ongoing cost. We've covered the local heroes and the popular cloud options alike, with honest notes on what each integration actually delivers.

Smart locks
Most smart locks are designed for American deadbolts and simply don't fit British doors. Everything here works with UK euro cylinders or multipoint locks — retrofit motors like Nuki and SwitchBot that turn your existing key, and full replacements like the Aqara U200. Each card notes the Home Assistant integration path and, critically, what happens when the battery dies or the Wi-Fi drops.

Blinds & curtains
Waking up to curtains that open themselves is the smart home's best party trick, and you don't need made-to-measure motorised blinds to get it. Retrofit robots from SwitchBot and Aqara motorise the curtains and blinds you already own, while Matter-over-Thread and Zigbee options integrate with Home Assistant fully locally. We note hub requirements and battery life on every card — both vary more than you'd think.

Hubs & dongles
The engine room: whatever devices you buy, you need something to run Home Assistant on and radios to talk to them. This page covers the official Home Assistant hardware (Green, Connect ZBT-1, Voice), the Zigbee coordinators the community actually recommends, and Z-Wave sticks on the correct EU/UK frequency. If you're starting from zero, a Green plus one Zigbee coordinator covers 90% of this site.

Robot vacuums
Looking for the best robot vacuum for Home Assistant? This is the one smart-home category where HA integration means account-linked cloud polling rather than pure local control — both Roborock and Ecovacs ship core HA integrations, but you're logging into their app account either way. What you get in return is real automation: vacuuming triggered by presence sensors leaving the house, mapped rooms exposed as HA areas, and dashboard control alongside everything else. Every model below is picked specifically for how well it plays with Home Assistant, not just cleaning performance — we flag the cloud dependency plainly and note where Matter picks up a handful of entities locally, so you can shortlist the best robot vacuum for Home Assistant without guessing at integration quality.

Smart wall switches
Not to be confused with the relay modules a few pages back — these are finished retrofit switches that replace your existing UK light switch plate entirely, no hiding a module behind the back box. Zigbee, Matter-over-Thread and Z-Wave options here, all verified for UK use, with the same no-neutral caveat that matters for anything pre-2000s: check what's actually in your back box before ordering.
