As he was installing bathroom accessories and stuff to water the plants in my new house, the plumber took a look at my job and the devices I was creating.
He told me that he had a temperature measuring device, that he could not find, back in 2011
He needed something like a data logger. Easy and light, cheap, with a battery lasting over year or so, that he could install at customers' places in order to have a Log of "what happened" if any problem came up.
Say, a frozen (broken) pipe or other malfunctions in heating, AC and such. He said connectivity wasn't necessary and to log to a SD-card that could be inspected later would be sufficient.
So we discussed the idea, and I made up a simple wired prototype. Later a real PCB was designed and some versions delivered for further testing.
Meanwhile, I discussed this device with other people and some of them thought of more ideas and other use cases, such as those described below.
We stopped as we were searching for the "most suitable" box, maybe a 3D-printed one.
Monitoring of walls and/or bridges was felt like an important issue to many builders, and indeed it seems to be of more importance, considering the collapse of a bridge in Italy last year.
