I had originally intended to use and rework the Daikin binding for use with my new Daikin Altherma low-temperature split air-to-water heat pump, but on further inspection it seems as if that binding is only for air conditioners. That binding integrates to either the KKRP01A or BRP072A42 units, which only seem compatible with a list of Daikin’s AC units.
Does anyone have experience or advice on the most sound way to integrate Daikin Altherma LT heat pumps? I’ve seen a somewhat expensive KNX module which I would rather avoid, even though the point at which it ties into the unit seems sensible (in the place of an additional controller using the P1P2 interface). There is also the CoolLinkNet unit, but only one of my indoor/outdoor models are listed as supported, and I have had no reply to my enquiry.
My specific Daikin Altherma models are:
EHVH11S26CB9W (indoor unit)
ERLQ011CV3 (outdoor unit)
Thanks for any suggestions!
