I guess this is really answering my question - there does not exist a
wireless 2 channel (CH/HW) programmer

Wireless 2 channel programmers exist, Danfoss go up to three channels
IIRC. The sticking point is the temperature control of the HW. I don't
know of a system with wireless tank stat and wireless programmer.

TBH if your tank stat wiring is three core and earth then I don't think
you need to go wireless at all. Wires work, wireless is not 100% reliable
and you have batteries to worry about.
