The cable had been chewed through and the sensor taken away. We don't know who the culprit was, but grey squirrel is at the top of the list of suspects. But magpies or jackdaws, with their liking for shiny objects, might be possibles, although it would be harder for them to break through the cable.
The squirrels have a track reocrd too! When the power to the garage was linked to the house by a cable along the top of the boundary fence they chewed through that wire and broke the connection. Every so often there would be a bright flash outside, like someone taking a flash photo, it took ages to work out what was going on. Presumably each flash was an electric shock for a squirrel, but it happened more than once so they weren't easily put off!
Let's hope that we don't have a repeat with the solar hot water sensor. This time black cable has been used instead of white and the sensor has been tucked away a bit more.
I'll keep you posted! I'd also be interested to know whether anyone has had the same problem - please let me know.

The sensor has failed in our flat plate solar panels. This event has made me realise the effect on me of having solar panels to generate our hot water. I have become attuned to how they work, almost subconsciously noting what the sun is doing when and whether there's any need to boost the hot water using the gas boiler.
It's not a case of keeping a record, using data or even feeling the pipe connecting the panels and the tank. It's not a technical process, it's an awareness of the outdoor environment.I hadn't realised it had happened until the panels weren't working. Even though I knew the panels weren't working I got caught out and found there was really cold water in the morning. I had based my decisions on use of the boiler on the amount of sun, completely forgetting the link had broken. Normally, with solar panels, there would still be hot water from the effect of yesterday's sun. However, without solar panels you have to use your boiler every day to get hot water, so it's in use throughout the summer when your space heating is turned off.
I am really looking forward to the new sensor being fitted so that I can get back into my solar cycle again. It's about more than the savings on our gas bills, which incidentally are noticeable following installation of the panels. Payback on the capital outlay may take time, but our bills now and into the future are lower, so worth doing.
