I purchased this after researching what was needed to use my Nest (gen 3) with my 2-wire whole home humidifier. It installed easily with some 0.2534; connectors and some pre-setup wiring I did following the Wiring diagrams in the Nest pro guide and some coordination with my furnace wiring. The mounting tabs made it easy to attach with a sheet metal screw and an existing hole in my furnace panneling. Now my wall just has the sleek Nest unit and no outdated humidistat.
