    We have used this of water, temperature and power monitoring at city service locations, in businesses and in homes. It works well and will continue to work for a number of years - twenty years in several locations. You do have to learn how to program it, but once learned it will do as much - or more - than you need.

    We use the 400 to detect possible electrical wire theft by monitoring exterior electrical panels.
