EmonEVSE charging with low current

I’m seeing some unusual behaviour during an overnight charging schedule. It’s happened a couple of times - the EmonEVSE appears to only draw enough current to charge at 1kw, which is well below what it draws even during PV Divert.

Do you have the pilot data for the same period?

The pilot has been consistently at ‘32’

Do you have any other monitor you can use to verify the power reading from the EVSE e.g smart meter display?

Yes, the consumer unit has a SDM120 with an LCD display.

I’ve just restarted the charger and it is charging at 32 amps again, will see what happens overnight.
