I have a french smart energy meter with an output that provides the data also available on the meter’s screen.
I had one Zigbee device inserted in there that I used to get the meter data and get that in the Energy overview. But it was unreliable and I changed to another vendor also transmitting through zigbee.
When I changed I lost the previous values from in the Energy panel. There may be a way to keep them or get them back, but WTH is that not automatic?
