Hi folks
I am slowly migrating a random selection of devices to ESPHome to save admin over time. Anyway - I have a few Sonoff POW R2 devices monitoring power and as a test I moved one of these from Tasmota where it was working well, to ESPHome. I used the config from here - Sonoff POWR2 | devices.esphome.io
The switch works however I dont see any readings from any of the power sensors. I did have to add parity: EVEN to the uart section as I got a build error saying that Partity couldnt be Null, but everything else I have left exactly as per the link.
Before I flash the rest, any reason why this isnt working?
Thanks
Heres my code if that helps…

This is all I see in the ESPHome logs - Nothing else gets added…In Home Assistant, all the entities just show as “unknown”

I meant runtime log, when sensor is updating…

Sorry, not sure how I would get that? I was assuming i wouldnt get any other logs as the UART is disabled as thats what I was led to believe the sensors use? Could you let me know how to get a runtime log? (thanks for bearing with me and trying to help by the way!)

If your device is online, afaik you should be able to see the log. I’m not familiar with different HA setups, but look for Esphome dashboard and click LOGS.

Ah, the log I pasted in my first reply to you is the log from the device via the esphome device builder…

Anyone else have any suggestions? Should what I am doing just work?
