huexpub commented 6 years ago

pzem004t use tasmota 5.10.b/g , diy esp8266 tasmota ,data have output a time ,then no data output all is 0V 0A 0W 0W 0 W , i switch pzem004t rx tx to espeasy ,is ok, so why ?

ionciubotaru commented 6 years ago

Please provide more details - pzem004t has a TX/RX output, you can read data using a FTDI via USB port. I suppose you want to upload the pzem004t output to a MQTT server using a ESP8266. By default Tasmota doesn't do this, you must disable Tasmota's serial, than modify the code.

Same problem, on sonoff rm not working, but on nodmcu work fine. I replace resistor to work on 3.3v. Then i try to use power from sonoff PCU and TX RX to nodemcu, an all work fine. Then conect back RX TX to sonoff and nothing.
