Use Flood sensor the other way around!

You can’t really submerse these sensors in water. But check out this thread. Should do the trick for you:)

My Christmas Tree low water alert setup

I wanted to get alerts when my tree water was low… I tried the Utilitech water sensor but it beeps when there is water. I picked up a PEQ water sensor from Bestbuy and I made a small bracket on my 3D printer. I connected a wire to the 2 terminals on the water sensor. [image] [image] I then zip tied the bracket to the tree at the height I wanted. Sensor hangs outside the tree. [image] I then used the No water app and I get push and SMS notification when my tree water gets low…works great. I was also thinking about making the tree lights blink…but the Flasher app does not list moisture sensor as an option.
