One of the ThingseeDISTANCE sensors is running special firmware that is customized to monitor machine usage times (vibration). I have attached that sensor to our washing-machine, so that I can see what kind of vibrations there are when the machine is in use.
The sensor is so sensitive that even walking by the washing machine causes some vibrations. So, you should read the diagram so that the machine is used only when there is a significant pike in the diagram. It is not running 24/7!
