Meross MSS620 Outdoor Smart Plug (UK)
- Wi-Fi
Verified July 2026
The go-to UK outdoor smart plug — IP44-rated with two independently switchable 13A BS1363 sockets for garden lights or a pond pump. Pair it with the meross_lan HACS integration and it runs fully local; no energy monitoring though.
In Home Assistant
| Control | Type | What it does |
|---|---|---|
| Socket 1 | Toggle | Switch the first outdoor socket independently |
| Socket 2 | Toggle | Switch the second outdoor socket independently |
| Combined switch | Toggle | Switch both sockets together |
The meross_lan HACS integration exposes three switches per unit — a combined toggle plus one per socket — so the two outdoor sockets can run on entirely independent logic (festoon lights on a sun-elevation trigger, a pond pump on an always-on schedule) rather than being switched together. No energy sensors exist since the hardware has no metering. A documented firmware regression (7.3.8) has previously broken HA control while the Meross app kept working, so a stale reported firmware version is worth checking if a socket stops responding.
