Hi!

Installed and wired according to the instructions. When starting the "esphome p1reader.yaml logs" I always get the following:

I wired the transistor incorrectly the first time which means that the signal inverter was not working and I didn't get any data on the RX-pin at all. When I checked the logs it was just idle so this leads me to suspect that I am getting some kind of garbage data "0xc6" that the python script doesn't like. Any suggestions?

My meter: https://brittedal.se/a/manual-till-elmatare-star

Please help!

Ok.. found the same issue here: https://github.com/esphome/issues/issues/313#issue-444213571

I guess ill try some other code to actually see the garbage I get in RX and go from there.

Slow progress.. I added a print statement in the python code of esphome just where it crashes. This is my readings from the power meter that I have repeated eight times. It looks like nonsense to me but at least it is somewhat consistent. Any ideas what i am seeing? This is just the first line as the program crashes after this, how can I make the script go on even though it throws an exception?

Ok.. I give up for today. I did check the serial coming in from the meter and it sends ascii. There is some garbage on the oscilloscope as well and I wonder if it is just the serial decoder of the oscilloscope having problems or if there is some kind of timing issue?. Any tip is appreciated.
