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.
What can Home Assistant control on the Aqara Smart Light Switch H2 (2-in-1 Neutral, Matter/Thread)?
| Control | Type | What it does |
|---|---|---|
| Relay switch | Switch | On/off control of the single wired load — the only control common to all three integration paths. |
| Wireless button | Event | Relay-less scene button with no load behind it. Zigbee2MQTT reports single/double/hold; ZHA reports single-press only; Matter mode doesn't expose it as a distinct trigger, only folding it into the same on/off cluster as the relay button. |
| Power monitoring | Sensor | Instantaneous power and energy readings, available only when neutral is wired and only surfaced through Zigbee2MQTT — not present in the Matter or ZHA entity sets. |
| LED indicator mode | Select | Configures the physical status LED. A Zigbee2MQTT-only config option; not exposed via Matter and unconfirmed as working through ZHA. |
| Power-on behavior | Select | Sets relay state after a power outage. Configurable in Zigbee2MQTT; not available as an HA-side control in Matter mode. |
The 2-in-1 name means 2 gangs sharing 1 relay channel, not two independent loads like the H1: the top button switches the wired load while the bottom button has no relay behind it at all — it's a permanently wireless-only key, decoupled by hardware rather than a firmware toggle. That hardware decoupling only pays off in Zigbee2MQTT, which exposes single/double/hold on the bottom button via its action state; Matter's switch cluster drops multi-click entirely and delivers plain on/off, so despite shipping in Thread/Matter mode by default, it's Zigbee2MQTT — not Matter — that actually beats ZHA here, and community threads report Matter-mode ghost switch events with no firmware fix yet. Re-flashing between Zigbee and Matter/Thread needs the Aqara app and a fiddly pairing-mode sequence that several users failed to trigger on the first attempt.

Frequently asked questions
- Does the Aqara Smart Light Switch H2 (2-in-1 Neutral, Matter/Thread) work with Home Assistant locally?
- Yes. The Aqara Smart Light Switch H2 (2-in-1 Neutral, Matter/Thread) is controlled locally in Home Assistant through a certified "Works with Home Assistant" integration (matter), so it keeps working if your internet connection or the Aqara cloud goes down. Control and state updates stay on your own network.
- Which protocol does the Aqara Smart Light Switch H2 (2-in-1 Neutral, Matter/Thread) use, and do I need a hub?
- The Aqara Smart Light Switch H2 (2-in-1 Neutral, Matter/Thread) uses Zigbee and Thread and Matter. To pair it with Home Assistant you need a Zigbee coordinator (for example a SkyConnect/ZBT-1 or Sonoff dongle) attached to your Home Assistant host; or a Thread border router (Home Assistant Connect ZBT-1, Apple TV 4K or a HomePod mini all work); or a Thread border router if it is Matter-over-Thread, or just your Wi-Fi network if it is Matter-over-Wi-Fi. Aqara's own hub is not required when you integrate through a certified "Works with Home Assistant" integration (matter).
