RS485 usage

[charlesjabged]

download this firmware file: https://www.kincony.com/forum/attachment.php?aid=6311
after download, unzip, just download BIN file to ESP32.

That exactly what i did. Then, i can connect to the wifi AP and go to the web interface. The software version is: 1.0.6. but the file linked is 2.2.6. 
Is there a why to check if the new firmeware was really written on the targeted device ?

Just to let yo know that, after multiple try, i was able to update the board successfully. Now, i am able to read 35 coils. The only problem is that the coils 1 do not correspond to input 1.
