There are a few members using this valve and I believe it does work with ST. Here is one of the device handler but you can also do a search for “leaksmart” and there are a couple more posts about this.
I won’t be converting the LeakSmart Water Valve DTH into an Edge Driver, but the device should be functional with the built-in driver.
This is a device handler for the LeakSmart Water Valve.
It polls regularly so you can use a SmartApp like the Simple Device Viewer to monitor it and receive notifications if it stops reporting.
The battery level it displays is just an estimate so every time it goes down a level you should test to make sure the batteries can still power it.
If you notice that the device is displaying 0%, but it still works on batteries or it’s showing more than 0% and it doesn’t work, please let me know so I can adjust the calculation.
