3. Shelly 3EM

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.
 

4. Shelly Pro 3EM 400A

Shelly Pro 3EM-400 is a three-phase energy meter for DIN rail mounting. Equipped with full gen2 firmware flexibility and LAN connectivity, it offers professional integrators additional options for end customer solutions. It can operate standalone on a local LAN and/or Wi-Fi network or via cloud home automation services via MQTT, HTTP and WebSocket. All incoming connections support TLS. The device reports the cumulative energy as well as the instantaneous voltage, current, active and apparent power per phase in real time. It stores data in non-volatile memory, which can be retrieved at 1-minute intervals for a period of up to 60 days. The device has a real-time clock to maintain the correct time if the connection to an SNTP server is interrupted. Shelly Pro 3EM-400 can be remotely accessed, set up and monitored by the user. The device can also access and communicate with an automation system as long as it is in the same network infrastructure. The device has an integrated web interface that allows you to monitor and control the device and customise its settings. The device does not have a built-in relay. The contactor is controlled via a Shelly Pro add-on, which is connected to the Shelly Pro 3EM-400. Scope of delivery: 3x 400 A current transformers 

5. Shelly PRO EM - 50

The Shelly Pro EM-50A is a DIN-mounted single-phase energy meter with an integrated switch for relay control.
