CRC Pass=no after a while

[makkanftw]

Hi! Recently built the P1 reader using the PCB from Naesstrom and using this repo and it works fine for a while but then I start getting CRC PASS = NO and then garbled data and after that nothing. I have S34U18 (Sanxing SX631) / Vattenfall with P1 active and using D1 mini MCU. Any suggestions?

I have tried this suggestion with no change: https://github.com/psvanstrom/esphome-p1reader/issues/36#issuecomment-1319105424

Also tried different cable and different D1 Mini, same behavior.

[Beaky2000]

I believe that the S34U18 (Sanxing SX631) sometimes and for unknown reasons take very long (several seconds) to transmit an update, and it seems that this reader does not work well in those cases.

It looks like there is a pull-request that will adress this so it could be that your problem will be fixed when/if that PR is approved.

You could also try my fork of this project, which I believe works well with the S34U18: https://github.com/Beaky2000/esphome-p1mini

@Beaky2000 I found your fork after giving up troubleshooting this one and has been working perfect for a couple of days now. Thanks!
