Setting the unit to become the boiler hub is easy (though may not be what you have in mind).

In the CLI enter

C 2

and the unit with switch to hub controller mode and will keep the boiler running for 2 minutes after the last call-for-heat was heard which is the minimum for use with FHT8V units.  If you have a good boiler bypass I suggest something like C 4 or even C 10.  Note that this mode should not be used with battery power as the receiver module has to be kept on most of the time.

C 0

will put the unit back in non-hub mode.

I would like to send this from the OpenTRV controller, but I can't figure out from the help text what I should send (and is timing important??). The valve STILL shows "AC" with a flashing antenna; so according to the manual it's awaiting said code.
