Shelly

The Shelly 3EM distinguishes and detects energy consumption and energy feed-in to the grid. The measurement data is displayed in the app, the optionally activatable cloud, and the web interface in clear graphics. Additionally, MQTT can be activated to register it with a corresponding MQTT broker. It is factory calibrated with the included clamps, achieving an accuracy of over 99%. Furthermore, it features a relay contact that can be used to control a relay, for example. Installation is done in the distribution box on the DIN rail. The measurement values are displayed in real-time. It is also possible to calculate energy costs. The Shelly 3EM can be controlled via the Shelly app, the optionally activatable cloud, as well as through MQTT and REST API. Energy consumption thresholds can be set, and when reached, the Shelly 3EM can switch off the power via the relay contact. Control based on time or sunrise and sunset is also possible. In addition to measuring energy consumption, the energy fed into the grid can also be measured. The Shelly 3EM automatically detects how much energy is consumed and how much is fed in, presenting this information clearly in a graphic. The measurement data is stored in the cloud for 365 days. The data is also written to a CSV file in 5-minute intervals, which can be exported by the Shelly 3EM. The Shelly 3EM features a programming and debug header that can be used for flashing alternative firmware. It is equipped with an ESP8266 with 4 MB of flash. It can be integrated into various smart home systems: Home Assistant, Hubitat, openHAB, Domoticz, REST API, MQTT, ioBroker, nymea, and HomeSeer.

Included in delivery: 1x Shelly 3EM, 1x user manual, 3x current transformers 120A.
