support Resol vBus

[isarrider]

Hi...

as a feature request:

Tasmota supports Resol vBus: https://github.com/arendst/Tasmota/pull/11114 https://github.com/arendst/Tasmota/pull/14189

I think vzlogger is the ideal tool to support it too...

BR, Alex

sounds interesting and doesn't seem hard, looking at the code in Tasmota. but this would need somebody who knows what vBus actually is, has the required hardware, and the skills and motivation to implement.

I have the hardware and can test...

attached is a sample that I get via ttyAMA raw.txt

the soldering is really easy: https://tasmota.github.io/docs/Smart-Meter-Interface/#resol-deltasol-bs-plus-vbus

can you explain why this is named "bus" when it's a simple one-way protocol? and/or can you point to any generic documentation for "Resol vBus"?

it would be 2 way... but to just grab the measurements out a simple circuit is enough... here is a lot of info: https://github.com/danielwippermann
