Shelly 1 Gen4 | Wi-Fi, Zigbee & Matter Smart Relay Switch with Dry Contacts
The Shelly 1 Gen4 is a compact smart relay for retrofitting into tight electrical wall boxes, offering Wi-Fi plus Zigbee and Matter support, dry contacts for flexible control, and local automations through the Shelly app. It is especially useful for lighting scheduling and DIY garage door or gate control, with the main tradeoff being that correct wiring and fit in the wall box can take a little patience.
