Sounds a bit complicated.

If you don't want the wifi integration fair enough, the models without
that are certainly not complicated, e.g.

You forgot to add the link to the receiver required to work with that
Heatmiser transmitter; both would total around £70.

They are *all* complicated compared to what the OP wants, and I am
speaking as one who has used wireless 'stats for around 15 years.

Our first one was a Drayton in about 2005, when we had a new boiler
installed. It worked ok for three years until the receiver failed. It
chose its time to fail carefully - we were just packing up the car to go
off on Christmas Eve! It was freezing outside, and I luckily had kept
the old wired thermostat in the "junk box". I connected it up in
parallel with the Drayton receiver using a flying lead. It worked well
enough to keep the house tolerably warm while we were away.

The second was one to replace the Drayton. Of course, I needed a new
transmitter as well to go with the new receiver (not Drayton. The price
of a new Drayton receiver alone was more than the prices of the
transmitter+receiver of the new one. I can't remember the make, but it
came from TLC). The new one had a faulty transmitter; it showed only all
the LCD segments or none. I took it back and the replacement was fine.
Except that the "Chinglish" manual was next to useless, as the setting
up directions for the 4-position DIL switch for channel selection were
nonsense. It took me some time to work out that their "left-right" meant
"up-down", and what they referred to as switches 1, 2, 3, and 4 were
actually 4, 3, 2, and 1. When I finally got the transmitter and receiver
to talk to each other it worked well for 4 years until we moved.

A couple of years ago we had the boiler here replaced. I wanted a
wireless stat again to replace the wired stat in the hall. We got a
Salus RT510RF (an earlier version of
https://salus-controls.com/uk/product/rt510rf-plus/). We don't need
the timer programming as we are here all the time, but do move it around
to where we are. It works well as a thermostat, but its physical design
is poor. It falls over very easily, and it is too easy to push one of
the buttons when you pick it up and change a setting accidently.

If the OP wants simplicity and reliability, an old-fashioned wired wall
thermostat is the way to go. It will also be the cheapest.
