As a starting point, here is how you can read the sensor: ``` text_sensor: - platform: modbus_controller modbus_controller_id: ${modbus_controller_id} name: "${device_type}-system time" id: ${device_type}_system_time register_type: holding address: 62 register_count: 3...
What do you want to change? Maybe I can do the change.
Did you find a RS232 with the same footprint as the RS485?

I will add this to the PCB. Did you connect GND on the RS232 side?
Something like this: 
And GND on the RS232 side? For RS485 GND is not connected on the A/B side.
I think jumper is not needed. I will just connect GND from the rs232 side to pin 8 on the RJ45.
I drafted a version. Not sure when I am done.
