Box Din Rail Pzem 004T x 4

Description

Modello

Support DIN Rail

This project was born from the need to want to monitor the power lines of the house, the project in question can handle up to 4 Pzem 004T and wanting with a little work you could expand everything up to 8 Pzem 004T.

• Customizable.
• Check your home consumption.
• Compatible with Home Assistant (Hassio)

Print Settings:

• Used Bambulab X1C printer.
• Infill 25%
• Supports yes.
• Layer 0.20
• Material used PLA or PETG or ABS.

Assembly material:

• 1 x Wemos D1 Mini ( ESPhome)
• 4 x Pzem 004T
• AC - DC Power 230v to 5v. (Power for Wemos D1 Mini)
• Hot Glue
• 4 pin connector for the wiring of Pzem 004T
• Terminal block 3 poles.

Specifiche ESPhome e Wemos

To make it work I attach below the code used on ESPHome, also in addition to the code was made a change on the Pzem 004T putting a resistance of 1.5 kohm, below the photo of the change, this serves to lower the voltage voltage to 3.3v. 
The wiring was done in series, then going in and out of every single Pzem coming up to the Wemos.
