These teensy multi-protocol relays work with every platform.

Shelly’s Gen4 relays start at $18 and can automate anything that’s wired, from light switches and garage door openers to sprinkler systems and appliances. Designed to fit inside electrical boxes, relays are a super versatile solution for the smart home.

Shelly’s new line is now available in the U.S., and all the models offer Wi-Fi, Bluetooth, Zigbee, and Matter (over Wi-Fi), so they’ll work with Apple Home, Google Home, Amazon Alexa, and more.
