Overview Shelly EM energy meter, 2-phase

The Shelly EM measures two circuits separately with two current transformers. A typical application is recording consumption and generation with one device. A relay built into the device can be switched.

Inputs
R1 Relay Switches the relay built into the device. The value is applied directly: 1 switches on, 0 switches off.

Outputs
R1 Relay status Actual state of the relay in the device. Is also updated when switching via the Shelly app or the push-button at the device.
V1 Voltage V L1 Mains voltage of the first channel in volts.
V2 Voltage V L2 Mains voltage of the second channel in volts.
P1 Power W L1 Active power of the first channel in watts. A negative value means feed-in.
P2 Power W L2 Active power of the second channel in watts. A negative value means feed-in.
W1 Consumption Wh L1 Meter reading of the first channel. Unit according to the power factor parameter.
W2 Consumption Wh L2 Meter reading of the second channel. Unit according to the power factor parameter.

Parameters

MQTT topic Topic of the device. Devices of the first generation automatically prepend shellies/, this part has to be entered here as well. Example: shellies/shellyem-AABBCCDDEEFF

Power factor Unit of the energy outputs. Wh outputs the meter readings in watt hours, kWh converts them into kilowatt hours.
In addition to the outputs listed, the command generate addresses creates an address named timeout. It is set to 1 when the device has not sent a message for a longer period of time.
