It is of the size and look of a regular Airsoft co2 cartridge. Located near the floor close to a heating radiator.
A small wire comes from the wall into it.
What is this thing?

Temperature sensor. Like this one: https://www.obi.de/heizungs-installation/heimeier-thermostat-kopf-k-mit-fernfuehler-weiss/p/7139603
Temperature sensor for the thermostat at the next radiator.
(it works on expansion of a liquid inside.)
