It can be done but it's not very professional and you will have hot water control features on your app that won't do anything. So, I would recommend changing it for a single channel version that is specifically designed for combi's.
With either version, if you have to open up a room sealed compartment to access the wiring terminals (with some boilers you do, some you don't) this is not a DIY job and should be done by a Registered Gas Installer (Gas Safe), who can make sure it is properly sealed up again afterwards.
However if you can't exchange the Hive, and can access the terminals without opening a room sealed compartment, it can be connected as follows:
The Dual Channel needs a N & L from the same 3A fused supply as the boiler. [see red circle]
The Hive (4) 'Heating on' connects to the top terminal where the wire marked bk1 is [see green circle]
No connection is required to the terminal where the wire marked bk2 is.
