openinverter forum

Hi All,
I have 2 open inverter boards using the esp8266 board, one for my small drive unit and another for my Gen2 charger. I can already access the web UI on 192.168.4.1.
I have been looking for detailed steps to update the web interface from the old UI to the new one on Git, but there don't seem to be proper step-by-step instructions on how to do it here. I tried the Platformio approach, but that did not work.

Does anyone have detailed steps on how to do it?

Hi tensa,

I had quite a lot of trouble as well a few months ago. In the end, what worked was to actually just bite the bullet and update via UART.

I posted my feedback here if you need a bit of guidance. If I were to do it again I would just go straight to UART reflash.

If you only want to update the UI you can just upload all files in "/data" one-by-one with the button that usually updates the inverter. Alternatively you can use curl as featured by Scrappy. No real need to use any of the OTA/UART paths.

Some versions tell you "Only .bin file" but you can ignore that.
