Via the smart-me API, you can use http queries to request meter readings from stations or use partial control capabilities.
These commands can be used by third-party systems.
The current scope is still limited and will increase over time.
Meter reading requests from OCPP stations (based on session data)
Meter readings from stations with integrated smart-me / eCarUp meters (based on 15-minute load profile data or faster)
Current power / currents or voltages and I/O from smart-me / eCarUp meters or stations with this integrated hardware.
Control of Pico charging stations and charging groups.
The information about the API can be found on this smart-me wiki page.
