Does the OpenEVSE WiFi have a MID meter for ERE registration?
No, the OpenEVSE WiFi does not have a MID-certified meter by default. For ERE registration, Joulo arranges an upgrade to a MID-certified charger, or you request a Secondary Allocation Point (SAP) with your grid operator with its own energy meter.
