It might be worth checking if you have real sheep skin seat covers fitted. (1 Viewer)

Ideally I guess, you would need 4 sensors, the fourth for monitoring inside the van itself,

Nope, no need for a 4th as the lower section of the monitor display is the inside or where the master unit is.
On my display, I have it set to scroll the sensors which are displayed in the upper section.

Thanks for the heads up on this.

Our van is in dry indoors storage and I've just checked and they are damp. They also taste salty.

We bought them in Poland 30 months ago but the van has been almost in constant use since then ( well until a few months ago)
Thankfully no damage to the " leather" upholstery.

Our “outside” sensor is in the EHU/Battery locker.
It used to be on the rear of the chassis but decided the locker was a good compromise for our use.
Fwiw ours is out of stock here

Ewe might try another source

As Two on Tour adds later, the indoor unit is the internal sensor, then you add external sneakers. Typical, up to 3 of those.

Yes I discovered that when the Thermo Pro units arrived, so with the main display being the internal sensor also, it still left 3 channels to detect 3 additional sensors, which the main unit scrolls through.
I am currently using it during lock down with the main sensor in the house, one outside(under the van)& one inside the van. Unfortunately the signal is not strong enough from the sensor inside the van to penetrate the house walls to reach the main sensor,(still working out best position placement) but will be OK when its placed inside the van.

I do recommend these units, but If buying again, I would seek a main unit with a digital clock also, as the Thermo Pro doesn't have this facility, some others do.

Well I have just done a taste test and undecided.
Could not really detect saltiness or acidity if alum was use to tan them, but I now have this urge to run around a field and be chased by a Border Collie.

I'll remember 'ewe'!
