When OCPP chargers connect and then send a BootNotification message, SolarNetwork always issues a GetConfiguration message, to obtain the charger model details and connector count. That is a very heavy-weight request, and when the OCPP service is restarted, causing all chargers to re-connect, then a huge amount of OCPP traffic is generated.

This issue is to propose that SolarNetwork only issue a GetConfiguration request if it hasn't already done so for a given charger, or to at least only issue such request "once in a while", to cut down on the OCCP traffic generated by charger connections.
