Energy meter EM Gen4 WiFi and ZigbeeArt. no.: 0900514
Shelly EM Gen4 is a two-channel single-phase energy meter that uses current transformers to measure energy data for loads up to 120 A. The device measures power, current, voltage and power factor in real time with a resolution of one minute. Shelly EM Gen4 also has a built-in 2 A potential-free contact set that can be used to drive an external contactor for controlling heavier loads such as water heaters, heat pumps and large household appliances.
Shelly EM Gen4 is easily configured and controlled via the Shelly Smart Control app or your preferred smart home system. Shelly devices work 100% locally and only require a local network to function. Shelly can be used standalone in the Shelly Smart Control app or with more than 200 partner systems such as Apple Home, Google Home, Amazon Alexa, Home Assistant, Samsung SmartThings, Athom Homey, KNX and many more.
Shelly EM Gen4 is designed for installation in a junction box or similar and comes with a 50 A current transformer. An additional current transformer can be purchased to measure a second circuit, and the device also supports 80 A and 120 A current transformers as accessories.
As part of the Gen4 series, Shelly EM Gen4 introduces multi-protocol connectivity with Wi-Fi 6, Bluetooth 5, Zigbee and Matter over Wi-Fi — for maximum compatibility and future-proofing. The device simultaneously functions as a Zigbee repeater and Bluetooth gateway, and supports scripting, MQTT, HTTP, HTTPS, WebSocket and RPC.
