Connected up to a Fibaro Door / Window sensor to monitor external temperature. Thermometer is mounted on a 3D printed holder.

Works as Expected
Wired one up to my Fibaro Universal Sensor, shoved it into my Hot Water Cylinder, Included it into my Z-wave network and hey presto, I can now monitor my hot water tank temperature. I now use it as a Z-wave thermostat to turn on my boiler when more hot water is needed. All works as expected and super simple to wire up.

Doesn't work
I wanted to monitor the temperature in my hot water cylinder. Connected up 2 of these sensors to a Fibaro universal sensor and tried to link that to a Vera Edge controller. After many hours of experimentation (Vera documentation is either very poor or totally lacking) it still doesn't work. I got half an answer from the Vera help line (which doesn't work but at least they responded). I got no answer from Vesternet (I phoned and they promised to call back, but didn't, I emailed and no reply).
