7x ABB Charger TAC-W22-T-R-0

[McFranky]

I have successfully integrated an ABB charger. After I integrated the second into the network with the same configuration, it is not recognized. How are the steps to integrate more than one charger?

Currently only one charger per central server is supported by this integration. You can create another central server that will listen to a different port (e.g. 9001) ad connect the second charger to that.

How many charger do you want to connect?

Thanks for your answer. It works now...

OK, one question to the Datapoint "maximum_current". With this Datapoint, I think, can I reduce the current for the charger (energymanagment). But this Datapoint is in status "not available". What is the problem?

It is only available if your charger supports the "Smart Charging" profile. You can check this in the value of the 'Features' sensor.
