For an EvoHome multizone setup, are these both usable as per-room thermostats? What are the differences between them?

Now I found a 3rd... Honeywell DTS92E1020 Wireless Digital Room.

I'm continually struggling to figure out what products are compatible with each other and EvoHome, since Honeywell do other ranges; is there not a single table listing this, or a nice brochure for EvoHome? I have my core system set up but feel in my large house, some non typical additions could be really helpful if only I knew what was available!

Then why the DTS92? It looks like an old fashioned version but does the same?

Maybe I should ask, if I have HR92 in my room for an existing EvoHome setup and just want the cheapest wall thermostat, which is it?
