@rafaelallouche I am also doing some reverse engineering of the EM5 solution at the moment (and bricked a EER31600 in the process :'( )

Be VERY cautious as the connection between the gateway and the EM5 is NOT LOW VOLTAGE SAFE : there is indeed 24V between terminals, but the 0V terminal corresponds to half-wave rectified AC at low impedance (as if this interface was powered by a half diode bridge). Bridging the 0V terminal to the mains ground will trip the differential protection at the breaker panel.

You definitively want to use an isolation transformer to power the EM5 when tinkering with this interface. In the EER31600 there is an isolation chip between the terminal to the EM5 and the rest of the circuit.

The protocol itself is 9600 baud serial ; with an optocoupler it is should be possible to connect a USB-UART converter or any dev board to listen to traffic
