Hi! Thank you for the great project! I really want to try it with my VP18EC which is about 18yrs old. However, my Server and the nilan (both panel and the cts600) are separated by a bunch of walls i do not wish to penetrate. I do have a bunch of esp32s and run esphome.io on them. There is an RS485 component available and with some level shifter one could use it to maybe interface with the cts600? Would you be willing to look info this?

I tried once to use this Combo in parallel with the display but after some seconds the display posted some error about lost communication and i gave up ...

Thank you!

As it is, this integration speaks directly with some serial RS485 adapter. Really there should be some intermediate communication layer inbetween, allowing for e.g. communication over esphome. Perhaps this layer should be the HA standard "modbus" integration, or something thereabouts.

Maybe someone with a better understanding of the HA architecture than myself could suggest what should/could be the appropriate RS485 layer?
