Not really, there are projects for getting a modbus TCP gateway running on ESP32 but most people use the ESP32 Dev kit: https://tasmota.github.io/docs/Modbus-Bridge/ https://github.com/zivillian/esp32-modbus-gateway That can then theoretically be used with https://github.com/kellerza/sunsynk...


I have captured the output on the Data+ terminal of my DC Blue Advanced with a logic analyser in PulseView. Data- stays low all the time, so it does not have data on it. Maybe Data- is the RX of the Motor.
The PulseView captures are attached for the following scenarios:
* Garage door open - we can see a minutely "check in"
* Garage door closed, opening, opened, until the light goes out
* Garage door openend, closing, closed, until the light goes out
It looks like a 1024 baud UART, but perhaps it's something else. The motor transmits a "check in" or "keep alive" message every 60 seconds. We see a message when the door starts to open, when it finished opening and when the light goes out. Same for the closing scenario.
Does anyone have any other idea what this is? It does not look like the T4 CAN protocol like described at https://github.com/xdanik/Nice_BusT4
