Thanks @athersaleem
Really nice work.
I have developed some stuffs for my Voltronic but with some esp8266 instead esp32.
- One ESP8266 connected to my Voltronic 5kw VMiii. Im using the ETH wire as power supply for the esp and ttl->rs232 board for 3 months without problems instead use external usb power supply. No LCD/Oled display.
- Remote 30A relay who is another esp8266 with a simple 30A remote for water heater
- Solar % chequer. Another esp8266 with a LDR (and optional oled).
- Surplus gadget. The last one esp8266 for visual non intrusive surplus consumption monitor. happy if active, sad if not.
ESP 2,3 and 4 connected via WiFi to the main (1) esp device who make the orchestation.
No mqtt (yet) but elasticsearch instead
have other stuffs like save input current, pv, output current, clouds, temp and wind every hour to a .csv file who can read trough FTP Server. OTA, espcrashsave, and other silly stuffs addeded to all devices...
This is the ligth server device (in this case, with little OLED):
