I want to be able to log the relative day by day temperature of my ufh. I propose to simply secure a DS18B20 temp probe to the ufh insulation approx half way between two ufh pipes before the screed pour. But are there any better suggestions? Does the cable need protecting from the screed material? from the screed installer boots? Thanks

As way of an experiment I've resurrected the old Raspberry Pi to see what sort of monitoring I can put in place with low cost components such as DHT11 and DS18B20 sensors. An hour or two of dodgy scripting on my part (god my python and bash is rusty..) and I've got a nice neat cron script that is logging data every 2 minutes pretty reliably. As I'm inherently lazy when it comes to backups and other stuff, I decided to use one of the online services for IoT to log to. Logic is that if I log at short enough intervals then any lost data points would be averaged out. I can also download the data if needed so it's not like I can't review the data offline Has anyone else done anything similar ..??
