2. Tapo (TP-Link) P110M Mini Smart Wi-Fi Plug, Energy Monitoring (Matter) — single appliances (matter)

The Matter version of Tapo's energy-monitoring plug, so it also works with Apple Home — but energy data is only in Tapo's own app for now.

Pros
  • Matter certified, works with Apple Siri
  • Energy monitoring in the app
  • No hub needed
Cons
  • Energy data not yet available over Matter
  • One socket only
  • No verified UK price

3. Tapo (TP-Link) P110 Mini Smart Wi-Fi Socket, Energy Monitoring — single appliances

A simple way to see what a single appliance uses, with no hub. It measures one socket only, not your heating.

Pros
  • No hub needed
  • Compact design
  • Alexa and Google Assistant support
Cons
  • One socket only — not whole-home
  • Not for high-power motors or EV charging
  • We could not verify a current UK price from an official source

4. Wiser by Drayton Power Micro Module — hard-wired circuits

A hidden, hard-wired module for monitoring and controlling a single circuit in a Wiser home. It needs an electrician to fit.

Pros
  • Monitors loads up to 3000 W
  • Integrates with Wiser heating automations
Cons
  • Needs a Wiser 2nd Generation hub
  • Electrician needed to fit
  • Not renter-friendly
