A leak sensor simply detects the presence of water between two small metal contacts on the bottom, about a 1/4" apart. You can put them anywhere including in your crawl space although I would put it in a low spot where water would first start to puddle. Some leak sensors have a probe you can remotely mount also.
The problem with water pressure sensors is there arn’t any I’ve found with Z-Wave or ZigBee built in. As you linked there are water “meters” which I suppose you could use…you can set it to alert if there is water flow for more then a minute or two. But you’ll have to install it right after your main meter and even then you’d still have to worry about the flow meter or your main water meter leaking…if there were a leek before the flow meter you’d never know.
Leak sensors are the “easiest” way to do what you are looking for. The water valve would be to stop the water once a leak is detected to hopefully prevent any damage but if your not worried about damage and more just about a $1k water bill the leak sensor (or a couple) is all you need.
This looks pretty cool. Have you inquired with the company if they have an API that can be used? If so, probably someone here could figure out how to make a custom device handler? Or, maybe use a “man in the middle” solution like a Raspberry Pi that could act at the intermediary between ST and the monitor.
I do have some questions about this. Can this be attached to one of the pipes near the water heater? I don’t have any other exposed pipe, other than outside…Also, unless I’m mistaken, anyone with a hot water recirculating pump will have “false” positives, as water is often flowing through the pipes. My solution to this when I was looking at another product that has not come to fruition on Kickstarter is to have the unit’s power turned off via a z-wave plug when “home” and turned on when “away…” When in “away” mode, the water pump would shut down and turn back on upon returning (this can easily be done via WebCoRE.)
I’m surprised this company hasn’t thought about integration with ST (or maybe they are working on it?) as they do have integration with Nest and Amazon Alexa.
turns out the Streamlabs monitor won’t be able to monitor the crawl space piping for leaks
unless I mount it in the crawl space where the pipe comes in from the street or city meter
the water has to be BEFORE the pipes you want to monitor
the usual mount position is after the water main shutoff
this allows monitoring water flow inside the house
but my goal was to monitor the crawl space
I’ve decided not to mount the monitor in the crawl space
as I can’t go in there and won’t be able to see the lights
or press the reset button - if needed - etc etc etc
I would also have to add a power outlet nearby, in crawl or on first floor
I have decided to use a Smarthings Water sensor F-CEN-MOIS-1
I will place a plank under the piping from entry to water main shutoff
and have it slightly angled with plastic over it and the F-CEN-MOIS-1
at the bottom
if any leak develops the water should get to the F-CEN-MOIS-1
I realize that this is an old posting, and @lbuttery couldn’t get the StreamLabs device working for his use, but if any of the others have a StreamLabs device, I created an interface to it for SmartThings. Take a look to see if this would help you.
This is also a concern of mine. Our deep well pump only replentishes at 2.5g/min and supplies two houses and a barn plus cattle waterer. If there is a leak, water pressure will drop in 10 minutes and pump will run until burn out. A z-wave or zigbee pressure sensor and a 2 pole 20 amp switch would be prefect. So far, I have not been able to find any 2 pole switches, save 40 amp for pool pumps. But a pressure monitor that coudl communicate with my smartthings hub would be great
