OCPP changeconfiguration timeout error

[carlosandtheo]

I'm obtaining a timeout error on the OCPP integration from ChangeConfiguration. The log is shown below.
HA obtains most variables from the charger but this error causes the charger to reboot every 60sec.
Any guidance would be appreciated.

Looks like you haven't selected any measurands to sample. You'll need to reinstall and select Voltage, Current.Import, Energy.Active.Import.Register, Power.Active.Import

Awesome, all works now thanks.
