Accurately and wirelessly measure the energy consumption of your appliances and solar panels. You can switch off devices in the event of overload via the switchable relay. Or use time-bound schedules. Shelly works directly with your WiFi signal, so you don't need a controller.
The Shelly EM Energy Meter with Contactor Relay Switch supports 110-230VAC, and has an ESP8266 with 4MB flash chip built-in. This makes it possible to flash your own or alternative firmware, such as Tasmota. This requires a USB-to-UART 3.3V and at least 350mA adapter, such as our FTDI adapter. And the great thing is, you don't even have to open the Shelly. Flashing is easy via the directly accessible pins on the outside.
