I have recently added a Shelly EM to my Victron setup. The EM comes with 2 channels which I thought would be ideal for my needs since I have 2 30 amp shore power inputs.
I used the mod by @Vincegod and got it working. But then I discovered that it only uses channel 1 of the EM. I have looked through the script along with the Shelly API and do not see what I could change/add to pull in channel 2 info. Has anyone does this? Or know what to change to pull in this additional data?
In the script you see some lines like
self._dbusservice['/Ac/L1/Power'] = meter_data['emeters'][0]['power']
The [0] is the first channel. If you change that to [1] you get the second channel.
To get both you have to extend the script or use a second instance of the same script. Running a second instance isn't the nicest solution but it is the easiest.
I do (almost) the same with a Shelly 3EM having all 3 channels assinged to a different function being the first acts like a external meter (for L1) and the second channel is as a PV inverter for the ac coupled panels (Enphase).
