Information

With the Shelly EM WiFi Energy Meter, you can wirelessly and accurately monitor and record energy consumption, such as from your solar panels. Through the output relay, you can connect the Shelly EM to a contactor and create smart circuits for situations like overload, pre-set consumption levels, or even remotely shutting down your solar panels during negative energy prices. The open-source platform allows you to integrate the Shelly EM with almost any home automation system. Shelly also offers its own free app, making it easy and affordable to set up a Smart Home system without the need for a Gateway/Hub.

Shelly EM WiFi Energy Meter

The Shelly EM can monitor up to 2 circuits:
Measure 2x Consumption (W)
Measure 2x Energy (Wh)
Measure 2x Load (max. 120A)
Measure 2x Load Quality
Measure 1x Voltage (V)
Additionally:
365 days of built-in Energy (Wh) history
230VAC/2A Relay output for Contactor.

Install the Shelly EM according to the user manual, connect via WiFi using the free Shelly app, and link the module. It couldn't be simpler! Don’t forget to order 1x or possibly 2x 50A or 120A clamps! If you have a 3-phase system at home and want to measure different phases, consider the Shelly Pro 3EM. There is also the Shelly Plus PM Mini Gen3 Energy Meter.

The Shelly EM Energy Meter with contactor relay switch supports 110-230VAC and has an ESP8266 with a 4MB flash chip built-in. This allows you to flash your own or alternative firmware, such as Tasmota. A USB-to-UART 3.3V and a minimum 350mA adapter is required for this, such as our FTDI adapter. The best part is that you don’t even need to open the Shelly. Flashing is done easily via the accessible pins on the outside.
NOTE: Never connect the Shelly EM to the power grid while flashing!

Also works with

Homey
HomeKit
HomeSeer
Domoticz
Home Assistant
OpenHab
MQTT

* Apple HomeKit requires flashing or a Homebridge

Prefer not to use the free Shelly cloud service but still want to control your devices remotely? No problem. Shelly EM also supports basic MQTT (Message Queue Telemetry Transport) for reliable connections via a central broker: the MQTT-broker. The connected devices only communicate with the broker and do not know each other. Therefore, they do not need to know each other's IP addresses or technical details. This is safe and reliable, with real-time monitoring and easy integration. Want to know more? Read our Shelly WiFi Switch Blog.

Wordt geleverd zonder A-meter, maar daardoor kun je de 50A sensoren meebestellen wat bij een standaard aansluiting voldoende is. De 50A sensoren zijn nog weg te werken in de groepenkast. De EM geeft in Home Assistant af en toe een storing van een verbroken verbinding maar werkt verder zonder problemen.
