Support for Shelly Pro EM-50

Hi,


I just received a Shelly Pro EM-50 and I would like to update the dbus-shelly to make it work.
I'm able to read the NotifyStatus to update the metrics but I have issue to find a good ProductId to use (0xB00C for now).

Two question:

How to set the view as a single phase meter compared to the Pro 3EM to avoid L1, L2, L3 phase ?

Does it already exist a two circuit meter on single phase supported by Venus OS ?

Thanks in advance.

Hi Damien,

I'm also trying to use the EM-50 as a grid meter, but struggling to identify the best way to do this (via modbus, via Outbound websocket, via MQTT, etc.)...

I would be most grateful if you might share your experience with this ?

Many thanks !

In the end I created a solution for Shelly PRO EM50 based on the excellent solution from Mr Manuel - it uses the MQTT service of the Shelly out of the box :

https://github.com/victronenergy/dbus-modbus-client/pull/4 I'm trying to get support for the Pro 3EM integrated into VenusOS, adding support for the single-phase EM50 would probably not be that much more work.
