Making an Energy Monitoring System

Making a 3-Phase Energy Monitor for Home Assistant. Three PZEM-004T are connected with an ESP8266. Using an Esp-Home, ESP8266 has been programmed, and the whole system is connected to Home Assistant. Dashboard panel has designed in a way that we can monitor voltage, current and power on all three phases, separately.

This is the tutorial 'how to put something in a case'....

Hello. Did you use a 5v to 3.3v voltage converter from the pzem to the esp?

[@federicos9821]

Hi, is there a reason why you never uploaded the tutorial of this project to your blog? Also i was wondering how is it possible that in your dashboard each line has its own voltage? Basically the Ct only detecta the current (A) so how does the software detects the different voltage between each line? 😅 thanks!

As you did the page or how you managed to link the data and that interests me a lot

Hi, congratulations for your work. Can you please tell what is the purpose of the diodes 1n4148 in RX and the purpose of the R1 of 10K between RX and 5V? Best regards

You have a very cool project, it would be possible for you to make a video explaining how to program the pzems from scratch and how the .yaml of the esp8266 would look like, I am trying to do it with 2 pzems+nodemcu v3 eso8266 but I can't get them to work with the documentation What's on the esphome website?
Thank you so much.

[@vasudevan84]

How do you handle if one of the PZEM loses AC Supply but the PZEM itself remains powered on? Cause PZEM displays the last known data(Voltage, current, power) instead of NaN when it loses AC In supply.

Hi, do you sell the board that you made to ESP?

[@cycu87]

When can we expect an entry on your blog about Energy Monitoring System?

[@witalkapuh5697]

Super.

[@barrybpl]

Nice.

[@kvamsidharvamsi5800]

can i pass phase/line wire through CT coil ??? can you share wiring diagram

[@fibranijevidra]

Could you please share a code and your HA config?

[@irfansensoy5901]

Hello. There are 3 pzem-004t v3 in my project and I am trying to get data with nodemcu. I can retrieve data for each pzem one by one without any problems. However, when I connect to D3 and D4 pins, whether I define an address or not, only the last address is returned and mostly data is missing. Can I have your code that shows the sensor readings except the important parts?

[@cycu87]

Brilliant project, I'm looking forward to seeing you update your blog. Regards and may more projects like this

[@abobija]

Thank you!

[@cycu87]

@@abobija If I may ask, what are the parameters of these three diodes

[@cycu87]

what should be the settings in the tasmot?
D2 GPIO4 -> PZEM0XX TX ,
D1 GPIO5 -> PZEM016 RX ?

[@alfione6]

hi which diodes did you use. thanks nice project

[@abobija]

Thanks, diodes are 1n4148

Can you post links to the soldering iron you use? I would like to buy one.

[@abobija]

Code name of soldering iron is SQ-A110, and link from where I've bought it is www.ebay.com/itm/353757369535

[@Roter_Wolf]

Nice project! Well documented, showing best practices, full HD camera and decent lighting. What more do you want?

[@abobija]

Thank you!

[@norbertkiss112]

Hi! Pls code and shema!

[@sajinraj-jy3rf]

Sir I want your project

[@semsuddin]

Predobro, moze li code i shema? 😊

[@abobija]

Naravno, planiram napisati uskoro blog post u kojem će biti navedeno sve što je neophodno za sastavljenje ovog projekta. Hvala na komentaru bro ;)

[@hazimalias]

@@abobija really appreciate it bro..
