PZEM-004 v3 #512

Closed sky7176 closed 3 years ago

sky7176 commented 3 years ago

I loaded the firmware 9.1.0 (sensors) on a D1 MINI to be able to use it with the PZEM-004 V3 I have configured the D1 in the following way: Tx GPIO01 -> PZEM0xx TX Rx GPIO03 -> PZEM004 RX

But with this configuration I was not able to get any reading from PZEM004

I changed Rx GPIO03 like this: PZEM016 Rx and by doing so I was able to get readings from the device.

Why does this happen?

Thank you very much

same for me as well. Upgraded from 8.5 to 9.1 and there you are! I was tearing hairs trying to find the issue until I discovered this thread.
