For applications where you want to have an in-wall switch (the ability to override the power while having the smart device hidden), this Zigbee 10A Relay Switch has come in handy more than once. These can be mounted inside an electrical box behind a switch/outlet and can work as a mesh device to extend your network or allow you to control the switch/outlet without replacement. It’s perfect for applications where you want to be able to control something but don’t have another good way to do it.
