Smart Home Assistant

Smart wall switches that work with Home Assistant

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.

Works with HALocal control
  • Zigbee supported
  • Z-Wave not supported
  • Wi-Fi not supported
  • Thread supported
  • Matter supported
  • BT not supported

The newer sibling to the H1 switches already on this site — H2 adds Thread and Matter on top of Zigbee, so it can join a Matter fabric directly instead of needing the Aqara hub for HA visibility. Still needs a neutral wire for this 2-in-1 variant, and it's a bare switch frame — budget for your own faceplate to match the rest of your wall plates.

The big brother to the X1i — a 6.9-inch panel that's genuinely pleasant to glance at, and the extra RAM copes better with a real dashboard than the smaller unit does. It's still fundamentally a light switch with a screen glued on: the relay talks to Home Assistant locally, but the dashboard is a browser you configure yourself, not built by the integration. At 87x178x36mm fitted, it's chunkier than most back boxes expect — check depth first. The base is swappable too: standard switches one circuit, but the optional 2-output power base lets the same screen control two separate loads. Keep layouts simple — cameras and animations show the tablet hardware's limits.

This isn't a Home Assistant dashboard baked into your wall — it's a real light switch with a 4-inch Android touchscreen bolted on, and you build the kiosk view yourself with Browser Mod and a restricted user. Do that, though, and you get a genuinely local relay switch plus a proper little control panel for one room, no cloud, no subscription. At 86.5x86.5x35.7mm with its back base fitted, it's about the footprint of a double-gang switch plate. As a single-room panel — thermostat, lights, a camera snapshot — it's a strong pick; as a whole-home dashboard it's underpowered, so keep it to one room's worth of cards.

Aqara Smart Light Switch H2 (2-in-1 Neutral, Matter/Thread)
Works with HALocal control
  • Zigbee supported
  • Z-Wave not supported
  • Wi-Fi not supported
  • Thread supported
  • Matter supported
  • BT not supported
  • not supported

The H2 shares the H1's 8A / ~1,840W resistive load rating, but its module runs noticeably deeper — 86 x 86 x 45mm versus the H1's 37.55mm — so plan on a back box at least 40mm deep; standard shallow 25mm UK boxes are even more of a non-starter here than on the H1. Expect to pay a bit more than the H1 for that dual-protocol Matter/Thread-or-Zigbee flexibility, not for extra switching capability. If you already run Zigbee2MQTT and have no interest in Matter, the simpler, cheaper H1 gets the same job done with less hassle. Needs a neutral wire.

4.7 (22 reviews)

  • Zigbee not supported
  • Z-Wave supported
  • Wi-Fi not supported
  • Thread not supported
  • Matter not supported
  • BT not supported
  • not supported

This is the non-dimming half of Fibaro's Walli pair, and it demands more from your wiring than a bare relay module: a neutral wire is mandatory, and it needs a full 60mm-diameter, 40mm-deep back box — check both before ordering. In exchange you get 13A per channel, 16A total, enough for loads the phase-cut Walli Dimmer can't touch. At £50.00 it still costs roughly double Fibaro's own Single Switch 2 module (£23.99) for the same relay function, and sits in the same finished-unit price bracket as the Walli Dimmer — pay it only if you want a complete switch plate, not a module hidden behind an existing one.

The dimming counterpart to the Walli Switch: a complete finished switch you fit in place of your existing one, not a module hidden behind it — expect to pay more than the £53-55 Dimmer 2 module already reviewed here for that finished-switch convenience, and factor in a compatible cover plate (Fibaro's own, or GIRA/Legrand/Schneider ranges). It only needs a shallower ~40mm back box against the Dimmer 2's 60mm, and like the Dimmer 2 it's no-neutral capable with a Bypass 2 module for low-wattage LEDs. Check bulbs are dimmable and trailing-edge compatible before fitting.

Same flexible-wiring ZBM5 module already covered here in 2-gang form, just stretched to a third gang for a landing or hallway with three separate lighting circuits. Same caveats apply: it's a bare module behind an 86-type back box, not a finished faceplate, and no-neutral mode has the same 3W minimum load and unconfirmed smart-bulb support as the 2-gang version.

  • Zigbee supported

  • Wi-Fi not supported
  • Thread not supported
  • Matter not supported
  • BT not supported
  • not supported

The with-neutral sibling of our no-neutral H1 pick — same plain Zigbee 3.0 device that pairs directly into Zigbee2MQTT or ZHA despite the box pushing the Aqara Hub. The neutral wire buys you two things the no-neutral version can't offer: full power/energy metering per gang, and Zigbee router duty for your mesh. It's rated 8A (around 1,840W resistive at UK mains), fine for lighting circuits, but the switch module itself is 37.55mm deep, so shallow 25mm UK back boxes won't take it without a spacer or deeper box swap. Expect to pay a few pounds more than the no-neutral H1 for the extra hardware.

Zigbee2MQTT / ZHALocal control
  • Zigbee supported
  • Z-Wave not supported
  • Wi-Fi not supported
  • Thread not supported
  • Matter not supported
  • BT not supported

The default pick for older UK back boxes with no neutral wire — despite the box saying it needs the Aqara Hub, it's a plain Zigbee 3.0 device that pairs directly into Zigbee2MQTT or ZHA. At 85.8 x 86 x 37.55mm it shares its with-neutral sibling's body, so budget a back box at least 35mm deep — shallow 25mm UK boxes are a squeeze. Max load is 8A resistive, but Aqara doesn't publish a minimum: very low-draw LEDs under roughly 3W per gang need anti-flicker mode to stop ghost-glow. ZHA support is thinner than Zigbee2MQTT's (no decoupled/scene mode), so Zigbee2MQTT is the better path for remote-style use.

MOES's tidier Star Ring design line — a backlit ring around the rocker instead of a plain plate — on the same no-neutral-required Zigbee 3.0 hardware as their cheaper switches. It won the Red Dot Design Award 2023, so it's the pick if you want a Zigbee switch that doesn't look like an afterthought, though you're paying roughly double what the plain MOES switch costs for that badge and the ring. It's rated 10A at mains voltage (100-245V AC) and fits a standard UK single-gang backbox, but treat that 10A ceiling as a resistive-load figure rather than a safe LED wattage number, given the flicker behaviour already noted below.

  • Zigbee supported

  • Wi-Fi not supported

  • BT not supported
  • not supported

This is the plain-plate sibling of the MOES Star Ring switch listed elsewhere on this site — same no-neutral-required Zigbee 3.0 board, same Zigbee2MQTT/ZHA support, just a flat white rocker instead of the backlit ring, at roughly half the price. Zigbee2MQTT supports it directly as the ZS-EUB_1gang (ignore the Amazon listing's 'Tuya ZigBee Hub Required' title text — that's generic Tuya marketing copy, not a real requirement; the switch pairs with any standard Zigbee coordinator). MOES rates it 10A total, with LED/CFL loads capped at 3-120W and incandescent loads at 3-300W (110V) or 3-600W (220V) — the LED figure is the one that matters for most UK lighting circuits. It fits a standard 86x86mm UK single-gang faceplate, but MOES doesn't publish a minimum backbox depth for this model, so measure a tight box before ordering.

Sonoff's flexible-wiring Zigbee switch: it detects whether you've got a neutral wire and adjusts its own operating mode, and in neutral mode it also doubles as a Zigbee router. Sold as a bare module behind an 86-type back box, not a finished faceplate, so budget for your own cover plate. The module measures 120×74×39.4mm — make sure your back box is at least 35mm deep before ordering. Load tops out at 10A resistive or 400W of LED per gang at 240V, with a 3W minimum draw required in no-neutral mode; Sonoff doesn't officially support smart bulbs on that wiring, and we haven't confirmed whether a bypass capacitor helps with flickery LED loads.

Frequently asked questions

What's the difference between a smart wall switch and a relay module?

A relay module (see Relays & dimmer modules) hides inside the back box behind your existing physical switch, which stays dumb but still works. A smart wall switch replaces the whole faceplate — the switch itself becomes the smart device, with its own Zigbee/Thread/Z-Wave radio. Pick a switch if you want a modern-looking plate and don't mind rewiring the front; pick a module if you want to keep your existing switches exactly as they are.

Do smart wall switches need a neutral wire in the UK?

It depends on the model. No-neutral versions (like the Aqara H1 no-neutral) work on old UK lighting circuits with only live and switched-live at the switch, by passing a tiny current through the bulb when off — fine for LEDs in most cases but check compatibility. With-neutral versions are more reliable but only fit back boxes that actually have a neutral wired in, which is common in newer UK builds.

Are Aqara or Fibaro smart switches better for Home Assistant?

Aqara's H-series switches are the cheaper, more flexible pick — Zigbee models pair straight into Zigbee2MQTT or ZHA with no hub, and the newer H2 adds a genuine Matter-over-Thread mode. Fibaro's Walli range runs on Z-Wave instead, which some UK users prefer for mesh reliability in RF-noisy homes, at a higher price point.
