Dear forum Got a BK7231N on a CB2S module, with a BL0937 = energy meter chip. I can reset the readings of the BL0937 chip to zero, but what I'd like is to set it to a specific value and let it run from there. I use it for monitoring a small set of solar panels, and I already have some 10 months...

Maybe this can help? Code: text Expand Select all Copy to clipboard EnergyCntReset [OptionalVal] Source:

Where 192.168.1.108 is the IP address of the Energy meter 269100 is the Wh preset (269.1kWh) And %20 is a space So invoke 269100 Change your IP accordingly.

Dear forum

Got a BK7231N on a CB2S module, with a BL0937 = energy meter chip.
I can reset the readings of the BL0937 chip to zero, but what I'd like is to set it to a specific value and let it run from there.

I use it for monitoring a small set of solar panels, and I already have some 10 months of data. I'd like to preset the 'Energy total' to what it has delivered so far.

Is this possible?

Thanks.

http://192.168.1.108/cm?cmnd=EnergyCntReset%20269100

Where 192.168.1.108 is the IP address of the Energy meter
269100 is the Wh preset (269.1kWh)
And %20 is a space

So invoke

http://192.168.1.108/cm?cmnd=EnergyCntReset 269100
