Can I swap the Smart Hub 2 with Smart Hub 3?
Yes
But beware it is incompatible with complete wifi (black discs) so they say.
How?
See page 2ff of this thread
But then I see you contributed to that anyway?
@licquorice I may have missed the obvious here, but how do you get a swap of the SH2 for an SH3 then?
From what i have read, you will need to recontract.
@licquorice so us mere mortals can't just swap out the SH2 then. (Told you I was missing the obvious. Thanks anyway).
