To start off both products work with Hubitat :-).
Cheapest this has been by $5 in awhile, last posted deal was around $75.95. It has been cheaper than this previously but not very common.
These things can be a life saver if your smart house detects a leak and saves you thousands of dollars in flooding. Also cool to use to open external valves for water/garden purposes.
While you are there can pick up the FIBARO Z-WAVE FLOOD SENSOR FGFS-101 $29.95
The flood sensor is also a all time low and currently $20 off original price or $25 off if your comparing it to amazon.
Overall a great combo and I bought 2 of each.
