Context

Set-up of a new go-e charger. This is my first attempt to set-up a go-e charger so have no idea of any specific change that could explain the error. Using the same charger with API V1 version works (I do have some transient connection errors - timeouts - due to unreliable Wifi connection but I believe this is not related).

Your Environment

go-e charger HW rev 3 running firmware 053.1
