Eve Energy is a compact US smart plug on Matter over Thread, rated 15 A (1,800 W), that switches a lamp or appliance and measures how much power it uses.
A compact plug for one lamp or appliance, rated 15 A (1,800 W) at 120 V, with a button on the plug to switch it by hand. Eve says it is not meant for EV charging or other continuous high loads.
Home Assistant adds it through the Matter integration without an Eve account and switches the outlet. Eve names Home Assistant among the platforms that show its energy readings. Because it is always powered, it also relays for battery Thread sensors such as Eve Door & Window and Eve Motion, which makes the Thread network stronger. A Thread border router is still needed on the network.
Buy the current version, which has the Matter logo on the box. Older units were sold for Apple HomeKit only and have to be upgraded to Matter first, which takes an iPhone or iPad and an Apple home hub such as a HomePod mini.

Recipes using this device
Recipes that can use it
These recipes are built around other hardware, and pick this device up as an optional extra.
Leak Auto Shutoff
Installs a Home Assistant automation that closes your water shutoff valve the instant a leak sensor goes wet, so a burst hose or a failed valve stops flooding within seconds. Add a smart plug to cut the appliance, a siren, and a speaker.
Solar Surplus EV Charging
Installs a Home Assistant automation that starts your EV charger when your solar array is producing a surplus and stops it when production drops, so the car pulls from the roof rather than the grid. Add a grid meter and a home battery and it holds back until they are happy too.
