@joshsinykin this is a bug in ESPHome 1.10, which has been solved in 1.11.
Disabling logging did not actually disable it correctly....

how do i get Washing Machine Power Usage - TODAY YESTERDAY ?

can i connect tmp sensor?

Hello.

Please how can I reprogram SONOFF POW R2 to run using ESPHome ?

Hi @frenck,
As always, it's a great pleasure to read through your work! Thank you!

@frenck, I have got one question for you here.
If I understand correctly what you achieved here, you used the blue LED to see when the washing machin is actually using more than 4 W.
If this is correct, why switching on the LED when the relay turns on? Why not waiting for the power to rise above 4?

You can use utility_meter inside ESPHome or in Home Assistant. That's what I do.

Go on esphome.io, they explain quite well how to reprogram it.
