Best Smart Plugs for Home Assistant (UK)
If you’re building a Home Assistant setup, a reliable smart plug is one of the easiest ways to automate lamps, heaters, and small appliances. The right plug gives you local control, energy monitoring, and rock-solid automations without relying on the cloud. In this guide, we highlight our top pick plus the best alternatives for UK users.
Key features of the Shelly Plus Plug
| Feature | Details |
|---|---|
| Connectivity | 2.4 GHz Wi‑Fi, no hub required |
| Home Assistant support | Native integration via local API and MQTT |
| Energy monitoring | Real‑time and historical power usage |
| Max load | Up to 3 kW (check your appliance rating) |

In Home Assistant, the Shelly Plug S exposes power, energy, and switch entities, making it perfect for automations like turning off heaters when no one is home or tracking the cost of always‑on devices. It pairs nicely with other devices we cover in our Best Smart Home Devices UK guide and works alongside in‑wall options like those in our Shelly Smart Relays Review.
If you want a plug that “just works” with Home Assistant, strong local control, and detailed energy data, the Shelly Plug S is hard to beat. Before you buy, compare the latest deals for the Shelly Plus Plug on Amazon.
