Re: Support for PZEM 004T Energy monitor
I figured out the numeric values, but when I open the log, it's empty (((
Re: Support for PZEM 004T Energy monitor
I have put the code in the file device.Lua?
Don't know for sure if this is the correct file? Or how to do this correctly.
I do get four separate values now, as shown in the picture below.
But indeed the log stays empty.
Hope you can help me out here.
At least I want to log Voltage and Current.
So I hope this will be possible with my setup
Many thanks for all the help.

Re: Support for PZEM 004T Energy monitor
Hi!
Regarding domoticz code, you have two choices :
- either you copy it in the domoticz/script/lua folder with a name ending by _device.lua eg pzem_device.lua
- either you go to the tools menu->more-> events, create a new "lua" "device" script named as you want and replace the default content by the code I posted
You also need to edit the first lines of the script starting by local dev,_... to match the name of your own devices
Btw, it's normal for the dummy pzem log to be empty as we overload the object. You'll get the log from the devices managed by the script
Hope it helps !

Re: Support for PZEM 004T Energy monitor
Thanks a lot!
I will look into that after work.
I have been looking for some setting regarding lua scripts as I thought I had to look in thst way. But didn't find any...
Now... I may have overlooked it, but can it be a specific version when it was introduced?
If i click update, It says it's the latest.
Thanks again!

Re: Support for PZEM 004T Energy monitor
it is not entirely clear what to prescribe after dev, could you describe in more detail, since I'm new to this and I'm hard at programming, thank you in advance
Re: Support for PZEM 004T Energy monitor
I can understand . This issue is now purely related to domoticz and not espeasy. So far, espeasy is doing the job correctly If it's ok for you all, I'll open a thread on the domoticz forum and upload a detailed tutorial over there. It'll be this week-end as I have no time for this during the week ; I'll post the link here when I'm done with it
Re: Support for PZEM 004T Energy monitor
That would be great!
Thanks!
Thanks!
Re: Support for PZEM 004T Energy monitor

Hi All !
Here is the link to topic on the domoticz forum on how to retreive the pzem values :
https://www.domoticz.com/forum/viewtopi ... 14&t=20820
Please note that in that post, I updated the domoticz script compared to the one I posted here previously to fix a few bugs, and for more accurate measurements
Feedback is welcome !

Re: Support for PZEM 004T Energy monitor
Hi, I did everything as you do, but in the device tab, the values are shown, and when you switch to auxiliary values by zero, what else could it be? It is not entirely clear what values to write when assigning a variable? Same as you on the screen or others?

Re: Support for PZEM 004T Energy monitor
Hi aleph0,
Can you tell me how connect pzem 004t to esp (my is a Wemos D1 mini)?
TX to GPIO 14 and RX to GPIO 12? only that? Directly without any resistance?
Thanks

Re: Support for PZEM 004T Energy monitor
@ruben : yes, I connected them directly without resistor to a wemos d1 mini. Pzem is powered with 5v, I read somewhere the wemos can handle 5v on the gpio pins, I wanted to test. So far it's working fine, but it's only ~20 days of continuous power up. We will see if it last
@gajotnt : I'll try to compile for 1Mb and tell you what. Will be on weekend !

How to know if pzem its working good? or its damaged?

Re: Support for PZEM 004T Energy monitor
Hello,
I have a wemos connected to a pzem running a few months ago, this sends the information to a PC with domoticz who keeps track of these variables.

Re: Support for PZEM 004T Energy monitor
giruchile can you show how you had connected pzem to wemos?
Re: Support for PZEM 004T Energy monitor
Hello,
for the connection I did it directly, but with 3.3v and I put a resistance in parallel within the pzem, the idea is that the optocoupler is running with 3.3v and not with 5v as it comes originally.
Now I'm not at home, I can barely get a picture of the change I made.

Hi. giruchile, could you put the compiled firmware with the plugin PZET-004 ?
Re: Support for PZEM 004T Energy monitor
It seems the plugin of giruchile is a different one from the oen I uploaded to the GitHub; it would be great to keep just one plugin per device to avoid duplication and confusion...
I don't mind even to remove mine if the other is better but I'd like as I wrote to make sure users won't get confused with this...

Re: Support for PZEM 004T Energy monitor
I actually copied codes from several sides until it worked. it is a very crude and imperfect programming.
I attach the code I use if someone wants to use it and better if they fix it, use it with espeasy 1.4 and mega espaesy.
_P099_PZEM.ino
in ESPEasy.ino add
I did not put all the values in the same device because I caused problems when integrating it in Domotics

As you get voltage value, it means the module communicates with the ESP. But you don't get current, thus no power : Check your CT

Then, I dowloaded the PZEM004T.io thast i added in the src directory and I also dowloaded the PZEM004.ZIP (containing the librairies, .h files etc) that I put in the lib directory and also download espsoftwareserial-3.2.3 in wich I modified the library.json as you mentionned and tried building a normal 4096 file and I got the following errors:

As I had to do some searching to finally compile and install it, here is a all-in-one summary of what needs to be done :
1/ Install and configure platform.io according to the instructions here :
https://www.letscontrolit.com/wiki/inde ... Platformio
then
https://www.letscontrolit.com/wiki/inde ... platformio
2/ Download the source tree from here :
https://github.com/letscontrolit/ESPEas ... .0.0-dev12 (or later version as there are being developed
3/ Download the plugin source from here and copy it in the main source
https://github.com/papperone/ESPEasyPlu ... M-004T.ino
4/ Download PZEM004T library from here and copy it in the lib subdirectory of the main source
https://github.com/olehs/PZEM004T
5/ Download SofwareSerial library in version 3.2.3 from here and copy it in the lib subdirectory of the main source
https://github.com/plerup/espsoftwarese ... /tag/3.2.3
6/ Update the library.json file that came from the softwareserial library with the following content :(version was missing and platforms mispelled )Code: Select all
{ "name": "EspSoftwareSerial", "version": "3.2.3", "keywords": [ "serial", "io", "softwareserial" ], "description": "Implementation of the Arduino software serial for ESP8266.", "repository": { "type": "git", "url": "https://github.com/plerup/espsoftwareserial" }, "frameworks": "arduino", "platforms": "espressif8266" }
After that, I was able to compile espeasy with the plugin and send it to the esp via OTA

When everything goes well, one module answer within 1s. But if you poll faster than 12s/module, your espeasy will crash in case of no measurment voltage.
And, of course I tested the bin file, I uploaded the one I'm using here, it's been up for 50 days now and doing the job fine

Because if i poll faster than 5 seconds update frequency is not periodic and updates randomely.
Anyways its working great...i am looking for 1 second update rate if possible
Re: Support for PZEM 004T Energy monitor
Yes, it's not that surprising : once in a while a value is not coming, triggering the timeout (1s each) and the retry (3 times). It's been reported the quality of 5v supply have an influence on this.
If you want to be able to poll faster, you need to edit the source code to shorten the timeout and no retry. In that case I advise you keep the error value transmitted (-1) and to manage reading errors in the host instead of in esp

Re: Support for PZEM 004T Energy monitor
Can you draw a schematic on how your module is connected?
The current is measured over a shunt resistor, but if no current passes through this shunt, nothing will be measured.

For those who have errors in reading, you must modify in the library espsoftwareserial-3.2.3, the SoftwareSerial.cpp file the following line:
Code: Select all
unsigned long wait = m_bitTime + m_bitTime / 3 - 500;
for this other:
Code: Select all
unsigned long wait = m_bitTime + m_bitTime / 2 - 500;

Re: Support for PZEM 004T Energy monitor
Hi,
Please forgive me but I'm new.
I have ESP12 and PZEM004 that I successfully used for one year sending data to ThingSpeak.
Now I have Demoticz system + ESPEasy. And I woudl like to add this energy meter to my system.
I downloaded bin file from:
download/file.php?id=1760
and uploaded to my ESP12.
Everything is OK beside reading of energy meter values, all are -1.
I think everything is OK from HW side but as I can see I have problem with correct settings of RX, TX lines in ESPeasy SW.
According to the doc I should use GPIO1 and GPIO3. But these lines are inactive in ESPeasy SW.
Could you help me in this case?

Re: Support for PZEM 004T Energy monitor
Hi,
Problem solved. Works grate!!! The problem was that my PCB was configured for use UART0 (GPIO1..3).
When I changed do 13-15 everything is OK.
But I wonder why the Voltage measurement is such unstalble ( I get -1 in most readings).
Any ideas? Update rate is 1min

Re: Support for PZEM 004T Energy monitor
Hello from yesterday I trying to configure PZEM 004 with ESP.
Everything is fine but some of the values are not correct. I mean the power is incorrect.
As you can see from screenshot ESP shows power 22W but should be 236.4 V * 0.18A = 42.55 W.
Can you tell me please how I can solve this issue?
I tried with formulas but without success.
Regards

With this module the ESPEasy plugin does nothing but fetching the numbers from the module and use them as they are.drfranky wrote: ↑02 Apr 2018, 14:47 Hello from yesterday I trying to configure PZEM 004 with ESP.

There's no calculation beside the ones done by the PZEM-004T itselft, so i can only guess the module you have does not work properly...

Re: Support for PZEM 004T Energy monitor
I'm not (yet) familiar with the module. But is it possible the power in Watt is correct and also the current and voltage, but that there is some cos-phi acting up here?papperone wrote: ↑02 Apr 2018, 18:24With this module the ESPEasy plugin does nothing but fetching the numbers from the module and use them as they are.drfranky wrote: ↑02 Apr 2018, 14:47 Hello from yesterday I trying to configure PZEM 004 with ESP.

What kind of load is connected to the sensor? Something with a true resistive load, like a heating element or something with an inductive load like an elektro motor or some switching power supply?

The load is power supply for my laptop. There is no cos-phi variable.
I tried to fix this with formulas in Easyesp but I don't know what is the variable for Voltage and Current in the fields.
