Here is an alternative multipurpose Visonic Door/Window Sensors Device Handler. There is a discussion thread about this sensor here
I was originally posting this DTH in the thread, but someone suggested I should start a new thread to make it easier for comment and searching. So here we go.
With some modifications, the sensor can be used as
- leak/water sensor
- smoke detector (for wired smoke alarm)
- tilt sensor to use for mailbox sensor or garage door sensor
Since they are only $10 a pieces, I can afford to put the modified leak sensors in every room which may have water problem in my house. Comparing spending like $30 a piece for a real water sensor in the market.
And if you already have a wired smoke alarm system, you can connect them to the visonic sensor and report status back to smartthings. You don’t need to replace them with smart smoke alarm just for that purpose.
And here is the screenshot when it is being use as different sensor function
And here is the device handler
And I also included the instructions for modification here
