No independent SL running from Hot Water Cylinder to Boiler

[legend99]

Hi,
Got a new boiler recently and was thinking of getting the plumber back to add weather compensation (it's an Ideal Logic Vogue). However, I think I have a problem as the SL for hot water cylinder, which is on floor 2, and the SL for the CH zone for floor 2, are connected together in a mini wiring centre next to the cylinder and thus only one single SL wire is going back to the boiler for the HW and CH zone for that floor. So, I can't distinguish at the boiler whether the call for heat has come from the HW or the CH zone - and I believe I need that detail as the HW should tell the boiler to fire up the temperature output to 80 to heat water.
Can any of you more informed people think of any solution to the problem? Is there any wireless solution that would allow me to pull one of the SL wires from where they are joined so that I'd be able to control the situation by saying having one still use the single wire and the other triggering a controller at the boiler such that I could control what happens there?
Just for info, I'm using Tado as things stand...
Thanks

Is there a spare core going from the wiring centre to the boiler ?

Unfortunately there doesn't appear to be. I think one possibility is that I have a Sonoff temperature probe on the boiler. I think I could use that to trigger a switch powering a SL going into the boiler. But a bit messy. Having said that, trying to get a new core back to the boiler from 2 floors above is even more messy. Or else I just give up the possibility of using Weather Compensation or OpenTherm and just stick to the smart TRVs

I would fit this to the heating side

MAINSLINK THE 5KM ORIGINAL SWITCHED LIVE CABLE REPLACEMENT SOLUTION

When time is critical or access is awkward - MAINSLINK the original switched live cable replacement solution, perfect for applications such as lighting and boiler pump overrun!

And use the cable core eg old switch live for hot water

Thanks a mill! Hadn't seen that product before - that could/should solve the problem actually!
