Great !

It means you used hardware serial RX/TX, doesn't it ?

Normally, you should be able to change it directly in the web interface. But first, you must disable serial log in the advanced page.

To be sure, I have just recompiled with the files directly from my github (library + .ino) for release 20190116 and it works. PZEM004T.png Maybe you could try setting PLUGIN_171_DEBUG to true in the .ino file and see if you get more information. And also, maybe try other pins and double check wiring...

I developped my own firmware to retrieve data throught MQTT if interested : https://github.com/seb821/espRFLinkMQTT

I forked the library and included modifications to get it to work with ESPEasy last release (20190116): https://github.com/seb821/PZEM004T The .ino plugin file I use is also included. To compile with platformio : - .ino file goes into source/src - other files go into source/lib/PZEM004T - in platfor...

I tested first with an Arduino Nano to make sure hardware was ok with code from these links: https://github.com/JhonControl/PZEM-004t-basic-ESP32-Arduino-ESP8266-Python-RPi/tree/master/PZEM_ArduinoNANOSoftSerial http://pdacontrolen.com/electricity-consumption-meter-peacefair-pzem-004-esp8266-arduino...

[...] I am a little uncertain what do you need exactly. [...] Because "#" character will be replaced by taskname and valname automatically. This is the default behaviour of the Generic MQTT controller. I can implement %taskname% and %valuename% if the above is not working with OpenHab. In...

Just tested it on an old Raspberry 1 and it is really nice. I like it. To keep everything consistent with other ESPEasy devices, would it be possible to take in account %tskname% and %valname% in the MQTT topics ? This is the default publish topic when selecting OpenHAB MQTT in ESPEasy : /%sysname%/...

It does compile with release 20181231. In release 20190107, it looks like they changed the name of the library from ESPEasySoftwareSerial to ESPEasySerial (in source/lib). These changes will have to be reported in the plugin .ino file and possibly in the modified PZEM004 library as references and ob...

@goldriver In the PZEM004T library folder, in library.json remove the dependancy to EspSoftwareSerial : { "name": "PZEM004T", "frameworks": "arduino", "keywords": "peacefair, pzem, powermeter", "description": "Enables communi...

Thanks for the link. It is great if there is a plugin for ESP Easy, I shall try for sure.

At the time, I believe it was not existing so I made my own firmware with the help of some existing code from github. It can be found here : https://github.com/seb821/espRFLinkMQTT

This is working for me with "RFLink" selected for event processing and this rule: On !RFLink#* do Publish test,%eventvalue% endon Or if you select "Generic" for event processing: On !Serial#* do Publish test,%eventvalue% endon I had to put a "RX Receive Timeout" of 10 m...
