ET112 reset Energy Bought

I have added a ET112 to my campers setup so I can measure consumed energy when on a pay connection.

What I would like to do is be able to reset the 'Energy Bought' back to zero when I hook up to a new supply. I believe this is possible through the Carlo Gavazzi UCS software but I hope to reset the ET112 counter from Node-Red over RS485.

I thought I'd ask here if anyone else has managed this so I don't re-invent the wheel.

Thanks for any help or suggestions.

No, I just do a bit of maths while storing values in a text file.

Hi,

I tried resetting the device using the Gavazzi UCS software but the total energy counter reset fails (returns an error). I discovered that my EM112 has the "PF" option in the model code, this means it is "MID" certified. The Gavazzi "EM100 Series and ET100 Series COMMUNICATION PROTOCOL" doc states:
> .... Reset of total energy meters (only for non-MID versions, X option)

That's why the command returns the error.
