Prometheus Endpoint

Metrics available for AhoyDTU device, inverters and channels.

Prometheus metrics provided at /metrics.

Labels

Label name	Description
version	current installed version of AhoyDTU
image	currently not used
devicename	Device name from setup
name	Inverter name from setup
serial	Serial number of inverter
inverter	Inverter name from setup
channel	Channel (Module) name from setup. Label only available if max power level of module is set to non-zero. Be sure to have a cannel name set in configuration.
