I made a decision to reflash them all. It is one-off operation. What cameout of this operatin that some of the sockets are using esp8266, but the firmware was upgraded so was not able to do cloudcutter on them.I had luck yesterday, no sunshine at all, so i could make the swap without losing solar energy. The next task would be to verify if my original MPPT (which looks the same as Easun but it's branded PowMR) uses the same protocol. It could be different as the menu and the displayed informations are not 100% the same, for instance it displays incoming solar power not just voltage.
You need to reflash all those MCUs? I prefer to buy Tasmota compatible devices or ones which has pin compatible Tuya MCUs with ESP12 so i can make a swap (like Tuya WBR3 -> ESP12F).
There is no modupus port on this charger... there is no port at allHmm, why not just ask the manufacturer for the modbus protocol ? Or maybe I am just missing something .
heyHello,
If it's not too much bother or too much to ask for, can you please post the wiring diagram for what you did? From what I understand you read the Serial information off the LCD's ribbon, but it is unclear what pins you intercepted. Same for the RS232 implementation.
Regards
You only need 2 pins from the display: GND (which is common ground with the converter) and TX (connected to the RX on the receiver side).Hello,
