RE: N30 Energy entry not working and power entry is wrong - Vega - 01-10-2026
Ok thanks
RE: N30 Energy entry not working and power entry is wrong - lulu01 - 01-10-2026
I have an N30. I use ESPHome. I updated the ARM CPU firmware. How can I check that the update is ok? Can I see the CPU firmware version number somewhere?
RE: N30 Energy entry not working and power entry is wrong - Vega - 01-10-2026
Look at the Current and Power enteties if they show the correct data, check it with a smart plug if possible, also you need to see the Energy go up.
Mine shows Current and Power but no Energy.
