Smart plugs & energy that work with Home Assistant

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.

Frequently asked questions

Which smart plug works best with Home Assistant in the UK?

The TP-Link Tapo P110 is the safe default — cheap, everywhere, energy monitoring, and Home Assistant's built-in tplink integration controls it locally. If you run a Zigbee network, IKEA's £6 Grillplats or the Sonoff S60 give you the same for less with no Wi-Fi congestion.

Can smart plugs feed Home Assistant's Energy dashboard?

Yes, if they report energy (kWh) rather than just power (W). Every plug on this page marked 'energy monitoring' exposes cumulative energy sensors that slot straight into the Energy dashboard's individual-device section — great for finding out what your tumble dryer actually costs per cycle.

How do I monitor my whole home's electricity, not just one plug?

You need a CT-clamp meter in or beside your consumer unit — the Shelly EM Gen3 is the Home Assistant community's usual pick and its clamp readings are accurate to about 1%. If you have a smart meter, a display like the Hildebrand Glow can also feed live grid data into Home Assistant without any wiring.
