Hi, the Topic we had somewere earlier as well.
Unfortunately the ESP32 on the DIYbms board does not have enough pins available.
May an enhancement could be, that in a next version the WT32ETH01 board could be used for the controller.
I love to use that controller in regards to exactly this topic, as Wifi is not that reliable.
