Hello,

I'm trying to compile last ESPeasy V2.0 release (ESPEasy-2.0-20180510) but I'm getting the same errors as #71 http://www.letscontrolit.com/forum/view ... 585#p22585.

Did anyone solve this issue? How to compile this plug in under the latest releases of ESPeasy software?
Thanks in advance,

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
i am also getting same error -1 randomely inbetween 1 minute readings... did you solved it ? what was the issue ? can you share ?

I have two pzem connected to my wemos ; I've also got this problem on one of them :-( I never understood what was the cause, I simply ignore wrong reading in domoticz. Not very satisfying, but enough for my purpose

Do you think its related to software library of arduino ? or TTL 5V to 3.3V Converter issue ?

I don't think so as the 2 pzem are connected on the same module, so same software library ; I also don't use any converters and connected 5V to GPIO directly. This is not conventional but I wanted to make a test and it's working 24/7 since last november, so I think it's safe enough ;-)

It's something related to either the pzem itselft, or the GPIO used to connect them. But as my setup is now kinda "in production" I cannot make any tests anymore :-(

I plan to buy some more for another equipment, it'll give me another testing possibility. But it'll be in a month or so

The signed/unsigned warning can be ignored.

The errors in WebServer.ino are also quite simple to resolve.
The functions used there in the "PLUGIN_WEBFORM_LOAD" case no longer need the first parameter "string"
So just remove that parameter:

addFormNote(string, F("SoftSerial: 1st=RX-Pin, 2nd=TX-Pin"));

Change it into:

addFormNote(F("SoftSerial: 1st=RX-Pin, 2nd=TX-Pin"));

I need to review this plugin in order to move it to the standard repository...
honestly still same issue, lack of time to improve it making it working with multiple devices (e.g. to monitor multiple lines or 3-phase AC).

Hmm, that's very strange, I only got those errors when building the latest ESP32 code.
Try to run a "clean" build first before recompiling.

Hello everybody,

My energy measurement is operationnal by following this post and this one http://www.domoticz.com/forum/viewtopic ... 14&t=20820
I use an ESP8266_4096.

But I have a problem :

- if I boot my ESP connected to the PZEM. My ESP doesn't start (no effect if I push on RESET button),
- If I boot my ESP (not connected to the PZEM), this one start normaly and after i can connect the PZEM to the ESP and the Energy measurement is OK.

This problem is painful because if i have a power cut, my Energy measurement does not restart.

Can you help me ?

Thanks in advance.

Maybe you connected the sensor to one of the pins needed to indicate the boot-mode?
For example GPIO0, which is connected to the "Flash" button on NodeMCU boards, will put the ESP into flash mode when pressed.
I can imagine the sensor will do the same when connected to that pin.

I modified the GPIO pin : GPIO-12 and 13 instead of GPIO-14 and 15 and all is OK.

I am not getting correct value for Watts when i did the calculation, example as below

Actual reading from meter = 232.20 Volts , 2.89 Amps, 665.00 Watts, 1311707.00 KWH

232.20 x 2.89 = 671.06 Watts, but in the meter it shows 665.00, can i know why its not accurate ?

Thanks in advance. :D

I also have some problem with building this project

I have two builds ESPEasy_mega-20181231 and latest with changed Softwareserial library
ESPEasy_mega-20181231 compiles without error only if espsoftwareserial-3.2.3 used
20190110 compiles with new ESPEasySerial library also without any errors
But both firmwares always shows me 0.00, even old version mega 2.00 dev

I think that is not a hardware problem, wifi-iot firmware works fine, but with the hardware serial.
Im already tried to change GPIOs to another with the same result.

Interesting that is no voltage measuring in the log, A W Wh only

Hi guys,

I got working on one esp-12f 6 of PZEM 004T. Probably I could connect up to 8 PZEM in the same time to one esp-12f.

The idea was to use many PZEM 004T on one esp-12f without using address of each one. I connected each one in parallel with RX, TX, and GND. For select with whom I am communicating right now I decided to use esp-12f ports.

If anyone interested I would share my schematic and plugin.

Thank you.

Hi guys,

Thank you for your interest.

There is a pdf how to connect them
Plugin for PZEM-004T.(I used one from playground but change it a lot)
Also I had to change Software serial ESPeasySoftwareSerial.cpp because original didnot work.

I think I did not mess something.

If you have a question, do not hesitate!

Hi guys,
I have developed many projects for my smart house but not sure when I should post them.

If someone lives in US or Canada, you might be interested in WiFi wall switch.
My idea was to use jst regular wall switch and put all elecrtonics right under switch button. You can see it on the photoes:

It is dimmable switch with two buttons.
I created plugin for it as well and connected to OpenHab.

Also I developed two version of Humidity/Temperature/Pressure devices. I use BME280 as sensor.
One of them looks like usb stick for remoute mouse or keyboard another one a little bit bigger.

@serjkru.
Please could you post the wiring schematic for the PZEM-004 modules to the ESP-8266 module,I do not see the pdf file.
Looking at the wiring picture posted earlier, you are sequentially supplying power to the PZEM modules and taking readings to send to openhab.
Good idea to save IO pins !

Hi all,
I'm using the firmware provided by serjkru and is working fine (pzem-004t v2.0)...good job :D
I have another question: is it possible to use the PZEM-004T V3.0 ? The firmware on the board has changed and I think the protocol is different, so no communication with esp.
The last board I got is 3.0 :(
Anyone is working with that kind of board ?

Thank you

Friends, I bought PZEM 004t v3, he refused to work on this firmware. I found articles in the network, how people use the corrected libraries for the PZEM 004t v3. Maybe someone of you can download a new library and upload it with a new firmware for 4mb?

gumilev If you need only one device you can use Tasmota software.
PZEM004T v3 uses same protocol as PZEM-016 So you need set proper rx and tx gpio's in config.

Thanks for the advice, it really works, this is enough to transfer data using MQTT to Domoticz. However, I will continue to wait for the plugin to be updated for EspEasy. In order to run pzem004t v3.0 in tasmota - it was necessary to enter only one line:

Code: Select all

{"NAME":"HW-655 PZEM","GPIO":[0,62,0,98,0,0,0,0,0,0,0,0,0],"FLAG":0,"BASE":1}
This is written in the wiki.
Then we assign gpio and go configure mqtt for data transfer!

Can you make an issue for it on GitHub and provide a link to this topic as well.

I have to order one of these sensors too before I can work on it.
But since I've been doing a number of Modbus plugins recently I don't expect it to be very hard to do.
Is it similar to model 017?

Unfortunately, I can’t help. My copy-paste programming level, all that I could find and try, I outlined above.
