As a SolarEdge user, it’d be cool if the Extended Data section could be utilised and/or customised for showing/logging extra data that is available via the API.
Perhaps when using Automatic Uploads there could be an option exposed for Extended Data where one can choose from drop-downs, the available fields from the given API to put onto the Extended Data page. e.g. DC Voltage, AC Voltages on diff phases, Reactive Power, Inverter temp, etc. whatever other values might be useful.
Probably a good Donation feature.
