After 0.5.8 connection reboots every few seconds

[Gnec220]

Hello,
I have a wallbox pulsar plus. After the update of integreation to 0.5.9 the connection to wallbox is broken. I get the following error in my logs.

can some one help me ?

[drc38]

Are you using the Skip OCPP schema validation option?

[Gnec220]

Yes i am using the skip ocpp schema validation option.

[drc38]

Try using the OCPP Configure service to set fewer measurands.

[Gnec220]

I tried that too. For example in the measuranda I choose only temperature. But the outcome itself didn't change.

[drc38]

See #1203 for downgrading to a version where you can select measurands on setup

[drc38]

Should be resolved in v0.5.12 as you can select measurands manually
