But it does not work DS18B20 It works on the original firmware I perform some test without problem on "ESP_Easy_mega-20191003_PZEM_core_ESP8266_4M1M.bin": I'm able to have DS18B20 and 2 PZEM on the same Wemos. My PZEM are connected with software serial on D1/D2 pin / Refresh 2s and 6s. DS18B20 is c...

Re: Support for PZEM 004T Energy monitor

Hello, i install the firmware pzem-004 v30 multiple, but only use one pzem, the problem is that the energy shown on espeasy is not correct. I tested on 1 PZEM with sucess.

Re: Support for PZEM 004T Energy monitor

NodeMcu + PZEM-004Tv30 (2pcs), works fine I requested "ESP_Easy_mega-20191003_PZEM_core_ESP8266_4M1M.bin" But it does not work DS18B20 It works on the original firmware I don't test this configuration. Normally, plugins are independant so my plugin shouldn't have any impact on the DS18B20. But I'll...

Re: Support for PZEM 004T Energy monitor

So, you have your answer about the connection of phase and neutral: do the opposite of me and it will work (I am from France). :D

Re: Support for PZEM 004T Energy monitor

There is no wrong way as it is AC. It can be connected in any direction. What is also confusing is the choice of colours. Here in the UK we use 'brown' as 'live' and 'blue' as 'neutral' (no red wires at all) - but maybe in China it's different ?? And about wires color, neutral shall be blue. Line ca...

Re: Support for PZEM 004T Energy monitor

I don't have clear answer about how to connect L and N. But I made so many test when I developped the plugin without taking care of the direction of L/N. And I never noticed that the measurements was negative (cos phi or current). Thus I can deduce that PZEM internal component detects the direction ...

If only one PZEM, then try select HW default, not SW serial.
Yes but orange and pink purple must be inverted to connect PZEM TX to Node RX / Node TX to PZEM RX

Re: Support for PZEM 004T Energy monitor

Hello everyone, Something to clarify for everyone: it's really not mandatory to use RX/TX pin of your WEMOS/nodeMCU => Any pin can be used with the solution of "software serial". Then, if you have trouble, first try to change for other pins. As an example, for my 5 PZEM on a WEMOS, here is the confi...

Re: Support for PZEM 004T Energy monitor

Hi, First I update my code since last month. Updated files are https://www.letscontrolit.com/forum/viewtopic.php?f=5&t=2595&start=100#p41093 . Perhaps it can help. Sources are now https://github.com/djelau/ESPEasyPluginPlayground Otherwise, you use GPIO1 as TX and GPIO3 as RX. I said "don't use HW s...

Re: Support for PZEM 004T Energy monitor

I don't know about domoticz, because I use Jeedom. But what I know is in Espeasy, it's not possible to have more than 4 data in a pluggin. To bypass this, you can create a second occurence of this plugin with the same PZEM address than the first occurence. In this second occurence, you can select th...
