Possibility to pair an ECU-B and this ECU ?

Open sebastianrothe opened this issue 10 months ago • 3 comments

Hey, thanks for the awesome project.

I would like to know if it is possible to pair multiple ECUs(this one AND the ECU-B) to one inverter? I need the original ECU-B from APSystems connected for extended warranty.

The other one always seems to lose the connection once I pair one of them.

You can try to enter the ID from your ECU-B into the ESP-ECU. Then both should work at the same time.

Thanks, I will give it a try.

Unfortunately, I can't get it to work with both ECUs. It is always working only for the one, I paired last.

In this zigbee network there is only one coordinator where the inververter is paired to. So no...
