Hello,
I have one edge instance connected to my backend and I have connected one power meter to it.
I can see live data in the backend UI, but in the history tab I see this (Error while fetching data):
as far as I know you don´t see voltages in backend´s history. What about your power channels? Are there any in influx?
Only channels are put to influx if there persistence priority is high enough. Usually the power channels in the electricity meter natures are high enough.
