Plugchoice
How Joulo connects chargers managed on the Plugchoice CPO backoffice.
Plugchoice is a charge-point operator backoffice, not a charger brand. If Plugchoice manages your charger, you connect with your Plugchoice account and Joulo reads the sessions from there.

How the connection works
Joulo authorises against Plugchoice with OAuth and lists the charge points on your account. Plugchoice caps its page size at about 15 rows whatever you request, so Joulo always walks to the last page rather than trusting one response.
What Joulo reads
Sessions come per charge point, each with a start time, an end time, the metered energy and the tag that authorised the session.
MID certification
Plugchoice is a platform. Whether your charger has a MID meter is a property of the hardware behind it. Joulo therefore classifies from the charger catalog, on the brand and model that Plugchoice reports.

Volt Time chargers also reach Joulo over this API. Plugchoice acquired Volt Time, and the Volt Time backoffice runs on the same platform. See Volt Time for what that means for MID.
Limitations
- Session detail is what the operator publishes, not raw meter values.
- The operator owns the OCPP connection to the charger, so the direct OCPP route is not available.
