DIY WiFi Home Energy Meter Analyzer with ESP32 and PZEM-004T

One day I was wondering:
Why my electric bill is always high?
How much electricity is flowing through my house right now?
So I decided to build my own Energy Meter Analyzer with an ESP32 and the PZEM-004T energy module.
It's a diy project which measures Voltage - Current and Power consumption.
On a small led display shows the Power consumption, and sends all data to a Thingspeak channel and (or) an MQTT Broker.
Now on my Android device i can view live measurements and a deep analysis of my home power consumption as well the cost of this.

Plz share the esp32 code...

[@papofuzz]

καλησπερα Σωτήρη , γιατι χρησιμοποιεις KAI μετασχηματιστη για τα 5V , αφου 5V δινει το PZEM-004T ? ο Κώδικας για το esp32 Που τον βρίσκω ?

[@sotiris_bell]

Καλησπέρα φίλε μου. Έβαλα τροφοδοτικό για τις δοκιμές και τις μετρήσεις που έκανα μεσω σειριακής... Τα 5v του molule είναι κατευθείαν από τα 220 χωρίς μ/σ, επικίνδυνο αν το αγγίξεις... Τον κώδικα δυστυχώς τον έχω χάσει αλλά αν θέλεις να ασχοληθείς έχει αρκετά παραδείγματα στο ίντερνετ.. Ελπίζω κάποια στιγμή να μπορέσω να ξαναασχοληθω...
