Description
Shelly EM Gen3 is a small form factor smart energy meter using up to 2 current transformers (contactless metering), which allows energy metering the consumption of electric appliances and reporting to a mobile phone, tablet, PC, or home automation system. It can work standalone in a local Wi-Fi network or it can also be operated through cloud home automation services. The Device has internal storage for data allowing for later retrieval. The Device has single dry contact switch for controlling external loads.
Shelly EM Gen3 can be accessed, controlled, and monitored remotely from any place where the User has internet connectivity, as long as the device is connected to a Wi-Fi access point and the Internet.
Shelly EM Gen3 can be retrofitted into standard electrical wall boxes, next to electrical appliances, power sockets, or in other places with limited installation space.
Shelly EM Gen3 has an embedded Web Interface which can be used to monitor, configure, and control the device.
