Wireless room stat/programmer with multi-channel receiver option ?

[SimonH2]

As a stopgap measure, in some rooms I have Salus RT510RF stats which I've paired with two receivers - one receiver in the room controlling a thermo-hydraulic actuator on the radiator, the other in the cylinder cupboard to switch the pump*. Eventually the plan is to hardwire everything as I redecorate each room and can chase in the boxes & conduits.
The downside is that I end up with a row of receivers - and I'm about to add a couple of rooms to the system so two more to go in.

What would be handy would be a similar stat (programmable like the Salus with multiple setpoints) where there's an option of a multi-channel receiver - i.e. I can have one receiver paired with 3 or 4 stats. Would make things a lot simpler at the pump end.

Does anyone know if such a thing exists ?

* Before anyone says anything - it's a modulating pump and the CH runs off a thermal store so no problem with dead heading it while the valves are still shut.

The Drayton Wiser allows 9 wall thermostats linked to same hub.

The whole idea with linked TRV heads is any head can fire the boiler, but when I started to set this up, I found a small problem, my radiators are against an outside wall, which means until the heating is running, and the thermal flow has been established, the TRV is colder to the room in general, so it starts the boiler too early.

With non linked, does not matter if the TRV opens, as the boiler is not running, so the Drayton option with wall thermostats seems to work well.
