I couldn't get this to work with uart0, it claimed this was reserved, but found and article which suggested that uart_modbus would work which it does :)

I have tried both with "uart0" and with "uart_modbus"
after flasing the device I get:

"Leaving...
Hard resetting via RTS pin...
INFO Successfully uploaded program.
INFO UART logging is disabled (baud_rate=0). Not starting UART logs."

the victron-mppt is OFFLINE

"WARNING Can't connect to ESPHome API for victron-mppt.local: Error resolving IP address: [Errno -5] No address associated with hostname (APIConnectionError)
INFO Trying to connect to victron-mppt.local in the background"

I guess it is something related to the wifi? I did check the user and password are correct .... ?!?
