This seems to do what I want, perhaps?
Noting the distinct lack of love in the reviews.

I am looking for something which comes on ABOVE a set temperature not
below.

Application is to turn the "beer fridge" cool box on when the temperature
gets up, but turn it off as the external temperature drops.

The crude approach is to run it all the time in summer, and run it during
the day in spring and autumn using a 24 hour timer, and turn it off during
winter.

An alternative use could be heating in the shed but I already have a
thermostatically controlled fan heater (or two) lying around.
Possibly to turn on an oil filled radiator or a tube heater?

Mainly looking for experience of similar devices and their reliability.

Cheers

Most ordinary room thermostats will do this, it's just a question of
taking the appropriate output from the terminals. At least
non-electronic ones do; don't know about electronic ones.

Don't you need something which senses the temperature *inside* the box?
The one you cite won't do that.

You can get room stats which have external sensors, which you could
probably put inside the box. How much power does the box take? Check
that it's within the switching scope of the stat. The one you cite
claims to switch 13A - but most room stats have a far lower rating than
that.

I bought one of these, to precisely maintain the temperature of my
5gallon fermentation vessel.

It is not strictly UK regs legal, but its works and is well made. You
can set it for on above a set temperature, or off above a set
temperature, with a settable hysteresis and it has a probe, which I
stick on the side of the barrel. You could put that inside your fridge.

Ah!
I recognise that one from Amazon - the reviews about electrical safety
were scathing to say the least.
So I think the word "strictly" is doing a lot of heavy lifting in your
description. ;-)

I also forgot to mention that the beer fridge is outside but under
shelter, which I don't think would make much difference as I have normal
electrical devices out there without any issues.

As for the thermostat don't think that it is feasible to run the cable
under the lid as the seal is a thin raised plastic strip in the base which
fits into a recessed rubber seal in the lid. A bit like the seal on some
plastic food storage tubs.
So it isn't like a thick soft rubber seal which will deform over a wire
but allow the lid to shut and fully seal.

Thanks for the link, though.


Cheers

Have you a link to the one on Amazon, I was unable to find it.

The one on ebay is a knock off of the very much more expensive inkbird
one.

The ebay one I saw (also on amazon) has an integral 'deathdaptor' the
inkbird seems to have a trailing two-gang 13A socket with separate
heating/cooling?

It depends on the Inkbird model.

It says 'no reviews' in that Amazon link. The obvious UK regs issue is
the lack of shutters on the 13amp socket.

I don't really see any controller being able to work very well, without
being able to 'see' the temperature inside.

I would see if there's a corner you can drill to put a probe through, and
then seal with expanding foam to insulate.

(assuming it's a standard fridge and not a water bath/etc)

From the original post, it was the *external* temperature that was
being monitored. Probably only turning the coolbox on when the weather
was warm enough to bother.

I assume that the idea is not to have chilled beer, but to prevent it
being overly warm on hot days.

Might it be possible to add proper thermostatic control to the coolbox
though? Presumably a small hole in the lid (usually only plastic and
insulation) would let a thermocouple or RTD be fitted and a simple
on/off temperature controller fed by that.

External temperature is all that I am after.

If it is below, say, 4C outside then there is no reason to run the cool
box and because there is no thermostat the inside can freeze at times.

Summer it runs all day. It is shoulder seasons where the temperature drops
at night but goes up during the day I am trying to refine.

I don't want to mess with the cool box itself because it also travels with
us when camping or caravanning.

Oh, and it does provide chilled beer. :-)

All the oil filled ones I've seen have an adjustable thermostat.

Something like this might work if your fridge is 250 watts
https://elixirgardensupplies.co.uk/p.../soil-warming/

or one of these will do 1Kw

The draw is 0.6A on the 240V adapter to 12V.
This is a cigar lighter adapter for camping ans the cool box is 12V.

So not a big load.
