Last gasp appeal before I contact the manufacturers..

I posted lats week trying to work out why the stat wasn't working
properly, and re-programmed it and fitted new batteries. (thought: I
hope they were new, anyway, must put a meter on them)

The symptoms are that it fails to be received occasionally.

I.e. the red light comes on steady.

If I go to the stat and reset the temperature to force it to come on or
go off then the fault clears. Possibly me standing by it improves radio
reception?

But, left to itself, in due course it fails to receive..or at least the
red light comes on..and it stays that way till I program a change of
state of the stat..

As I understand it, it should transmit every 5 mins or so..it seems not
to be doing this...

Any ideas?

Got a scanner so you can hear what's happening on that frequency?.

No Tetra masts nearby that are de sensitising it?..

No and no..

Is it 2.4 Ghz?

No.. around 433 MHz IIRC could just be on a null point perhaps, pity
you can't hear it on air...

Is it on the same frequency as your or a neighbours, wireless router?

Try moving it closer to the receiver to confirm it works. If as someone
suggested - it works on 433, that is an radio amateur frequency.
Perhaps you have an active amateur living near or an amateur repeater
on the same or similar frequency. There is not much you can do, they/we
have priority.
