Hive stuck on Receiving and boiler not turning on

pieroabcd

Hi,
I had noticed this odd behaviour in the past, but now it's happening more frequently. This morning the heating system didn't turn on.

What happens is that the temperature drops, but the hive doesn't turn on. When I press any button I see that it remains stuck on "Receiving..." For a dozen seconds after which it shows "no signal".
I have to insist a bit raising the intended temperature with the knob and also I have to press a button on the boiler display.

The hive control unit (receiver?) that is near the boiler shows a red button at the bottom, that becomes green when the boiler finally turns on.
I think that this is a Hive v. 2.

Any idea what's going on?

Thanks

The hive doesn't use WiFi (for which it's not even enabled).

do you need to change the batteries ?

These are brand new

What's the distance between the stat and the receiver? Any new WiFi/Bluetoothy devices added to your home recently?
The next time it doesn't work, unclip the stat and bring it closer to the receiver, and see if it links.

It must be 5 to 5.50 metres, with a wall and a cupboard in the way.
Yes, keeping it closer to the boiler worked well and stably, but I had never seen it so persistently stuck before.

No new devices in the house of any kind.

It must be on the verge of a weak signal, then, and something could be adding that wee extra touch of interference that makes it break up. Could even be a neighbouring WiFi or room stat!
Where is the receiver mounted? Can it be moved, ideally upwards, even by a foot? Does it have enough cable to allow this? If so, experiment with sideways positioning too - chances are there's a sweet spot that'll give a stable signal.
Or, can you move the stat itself, not necessarily closer (tho' that's the obvious), but just somewhere different?
There could be all sorts of reasons why the current positioning is dodgy - a bit of metal corner plaster strip, some foil-backed insulation, etc. Or just the distance.

There's no cable: it's battery powered, that can be an advantage or a disgrace.
Now I've tried with new Duracell.
It's in the hallway, far from the radiators.
Moving it is quite easy, I'll see where it works best.

The receiver, man - the bleedin' receiver! Does that have adequate cable? :-)
I have a Hive myself, and the batteries last well, long enough to not feel an imposition.
Is your sitting room closer to the receiver location? If so, that's a better place for it anyway, imo.

pieroabcd

Ah that! No, really it couldn't be tighter! Not an inch of free cable.
Yes, there's a spot in the sitting room that is far from the radiators and closer to the boiler.

Cool. Let us know how it works out, please.
Once positioned in the sitting room, you should remove any TRVs in there - just remove their heads and put wee loose caps over the valves, or simply open them to '5', and even slacken the heads slightly if needed. The Hive needs to become the sole temp controller in there.
Your hallway rad should then become TRV-controlled in order to keep the temp in there stable.
If the hallway rad doesn't have a TRV, and you can't be bothered fitting one, just tweak the control valve until it gives you the hallway heating you want relative to the rest of the house.
