Charger changed into error state

Chargepoint <CP_ID>: Changed into error state.

Trigger

The charger is reported to be in an error state. The cause may be any of the following, though the list is not exhaustive:

1. Charger is has lost connection to HARMON-E, it's offline
2. Charger has not reported its state ("Unknown State")
3. Charger rejects Smart Charging Profiles
4. Charger does not respond to Smart Charging Profiles

Remedy

1. Find the cause for the lost connection and re-establish connectivity
2. The proxy issues a TriggerMessage, requesting the charger to send a StatusNotification when the connection is (re-)established. Verify that the charger is correctly accepting this message, and more importantly, actually sending a StatusNotification afterwards.
   
   --> The state which the load manager assumes as default can be changed via the Default Status config parameter.
   
   
3. This could have many causes:
   1. The firmware is not certified and hence the charger needs to be updated
   2. Some chargers require a specific configuration before they accept Smart Charging Profiles, so check the settings if you can activate Smart Charging on the charger
4. Same as the previous steps
