Compatibility to Buderus Logatherm WLW286 A / WPM100

[git-developer]

I'd like to know if this project is compatible with a Buderus heatpump Logatherm WLW286 A driven by a Logatherm WPM100 control unit.

I wasn't able to find out if the device has an EMS interface yet. The best I could find in a technical brochure (PDF) is this diagram:

Looks like there's a CAN bus between heat pump and controller, and an option to add a hardware adapter for KNX.

I'd appreciate if someone could give a hint if these devices are compatible with EMS-ESP32, or how to integrate it into a smart home system otherwise.

I guess chances are low to gain insights when @bbqkees has no idea.

I think I found out some details that I'd like to share.

• It looks like this Buderus heat pump is made by Dimplex, not Bosch.
• The touch display controller Logamatic WPM100 is a relabelled Dimplex WPM Touch device
• The connector labelled BMS card is a slot that may hold
  • either a LWPM 410 (article no. 339410) for Modbus RTU
  • or a NWPM Touch (article no. 378800) for LAN or Modbus TCP
  • or a KNX WPM (article no. 376350) for KNX
• Technical details for these extensions are described in the Dimplex wiki

If this correct, the EMS-ESP32 ist not compatible with this heat pump.
