GivTCP integration into HA ... and sensors names being changed

Dear all
My GivTCP inverter had to be restarted due to firmware problem.
It seems that all of the GivTCP sensors had “_2” added to them. The original sensors were inactive.
I had a look but I cannot find where the sensors are defined in HA. Thius naturally caused my dashboard and automations to fail.

I see for the files in GitHub that there is a givtcp.yaml file which does define the sensors but I cannot find this on my HA installation, but it must be there as the sensors are being created.

Can anyone help, as I am tearing what little hair I have out?
Thank you
