Feature request: relay mode #28

Closed dwmw2 closed 1 month ago

dwmw2 commented 1 month ago

It would be really useful to be able to keep the Melcloud wifi adapter connected while also using esphome.

If we have two UARTs available, can't we relay commands from the wifi adapter to the heat pump, and relay responses (or all messages?) back?

I actually use this setup to reverse engineer those missing cmds (proxy between master and a slave). There's already a discussion about this topic here https://github.com/gekkekoe/esphome-ecodan-hp/discussions/20

I also think that except for the MMSP incentive in the UK, there's no compelling reason to keep the melcloud adapter when running esphome? But you might be able to provide the data from HA instead of melcloud? You would also need some extra hardware and do some soldering. A custom pcb can be made, but that takes some time and rework the software for it. It a lot of work and there's no gain for most users. Probably there's not enough demand for this to make it viable.
