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

https://www.thesmartesthouse.com/...chip-model

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.

Would be great if we could use with Ring security and their flood sensors... Most other monitoring tools require to be placed inline. This just remotely shuts off the valve.

Other than Ring security I've been doing HomeKit so that would be a challenge to add these z-wave to that...

Your exact issue is why I choose Hubitat when deciding on a long term totally versatile smart home solution. It works with all the big protocols, gets weekly updates to its firmware, all works "LOCAL"!!!! So even if the company ever goes under my home automation can run indefinitely without any issue. Has a extremely active community, for the most part anything that Smart Things supports so will Hubitat, if not one of the code wizards on the forums can usually repackage the ST drivers and make it workable on Hubitat. Not to mention its pretty inexpensive to buy a Hubitat.

I've had this for the past couple years. It's very well engineered and quite powerful. I've linked it up with a water sensor and with a smart hub. Highly recommended.

FWIW: I have a well system with a softener, chlorinator, and UV sanitizer. I have PEX plumbing and was affected by the bad PEX junction issue where the brass parts corrode and leak.

Does this present any flow problems? Does it sit on the high pressure or low pressure side of the inlet?

This doesn't affect the pipe at all. It's literally a motor with an arm that physically turns your existing valve.

Dome makes good stuff. I would really like this but unsure if it can work in my application. My main valve is close to other stuff so if this needs to be mounted directly in line with a pipe, I might have problems. See the photo: Anyone know what that other stuff hooked up to the left of the shut off valve is in my photo? It seems to be 220v and connected to the well pump outside.

I wonder if I really need a valve shut off on a well system. Can't I just turn off the power to the well? Sure, I'll need a 220v z-wave controller and my pressure will need to bleed out of my well tank, but wouldn't that work?

Thanks in advance!

Ok, the shutoff itself is great. You need a hub, hubitat or smarthings, although if the ST cloud is down or acting up or your internet is out, you'll likely still get flooded, but not with Hubitat.
The fibaro flood sensors are absolute garbage. I just checked my 4 sensors, even tho they are on constant power and set to report temp every 5 mins, guess what, last time they reported was 6-15-19, yes 2 months ago. They suck.
I do have to say I suspect if I went and dunked them, they would report and shut off the water, but I absolutely hate having to test them that way, they should just report, as they are configured to do. I thought having THREE z-wave hardwired repeaters in my 25 x 25 foot basement would help, nope.
Went and bought 4 samsung flood sensors, those always report, and placed them next to the fibaros, which i should just throw out.

Lastly, make sure you have a ball valve as a shutoff and that the valve is not too hard to turn, or this motor won't be able to shut off the water.

PS- just went downstairs and moved the fibaro, and it reported acceleration. It's quite frustrating to have to babysit these things to make sure they are working, to avoid explaining a flood to the wife after spending all this money on the equipment.

I'm by no means an expert... in the event of a power failure/turning off the pump via the electric (which seems like a pretty good idea, I hadn't thought of that) how much water will still come out just from the pressure tank?

Edit:
Per https://www.skillingsandsons.com/...-tank-work
Looks like the average pressure tank is 44 gal and has a draw down of 16 gallons... that's a decent amount of water to still let go through in the event of a leak, so I'd think a pipe valve is going to be the better solution.

Very interested and thank you. Not sure I'd depend on just the sensors. Can I have my ring alarm, when set away to shut the water off, and when disarmed, the water valves opens back up? Or when ring alarm is armed, a sensor I can mount to pipe that will pick up water flow through noise and vibration, then the various will close. I'm usingsmart things.

As someone else mentioned this replaces the manual knob that gets turned to turn on or turn off the water to your house, so it does not sit on neither its right at the main access point.

You would still get anywhere between 50-100 gallons of water dumped into your house, which is unacceptable, and easily 10K in damages.

This is so cheap as long as you have a good LOCAL hub and have it hooked up to a battery backup for power failure situations its piece of mind on the cheap.

As for the other stuff thats simply the cable you would plug into a power outlet to keep the Dome device powered, I recommend plugging it into a battery backup along with your home automation hub for obvious reasons.

In Hubitat they added a driver specifically not to long for the Fibaro so do you know if your using the built in driver? Also judging from reviews the temp is the big variable but the wet/dry always work like a champ so for $25 compared to all the other sensors being $30+ I would say this is worth it, also not sure what the advantage of knowing the temperature of the water flooding your house is, when the main valve will shut off both hot and cold since they come off the same inlet? Very curious what you use the temp functionality for? I can see them being used in like pools when water gets to hot to open maybe a cold inflow to level out the temp, but in a house I am not sure.

I am no expert but I heard constantly messing with your main water supply by opening and closing it can cause your o rings in sinks/faucets and seals to increase failure rate. Thats why they always recommend running the water and having faucets in the on position when turning water back on till the pressure settles so its less stress full on the plumbing. I could be 100% wrong but thats what I read or hear on a few youtube videos.

Yeah getting a trust worthy sensor is something, but you could always do backups like add a secondary sensor and even add a webcam at the failure point to visually verify before closing the water valve remotely yourself. So you would get a notification on your phone, remotely view your cam, and hit your dashboard button to shut off the water yourself. Also Hubitat will let you set rules where you can set both sensors to read wet before the main valve gets closed or force it to close if one reads wet and the other dry. So even if one sensor fails the second will catch it and the rule will execute to close off the water. These sensors from my resarch are super reliable on the wet/dry reading and its almost instant, the temp reading as pointed out by my fellow Hubitat user RichardR is another story. This will be my first Fibaro water sensor so I am not speaking from experience just from my own research. The Fibaro name brand in HA in general is very positive when used in conjunction with their own HA hubs.

I've got two installed in the crawl space at our beach house to shut off the water for our outdoor shower. Use the Wink hub. Works fine. Would have used a different hub but don't have a need to add any other devices.

My water main valve is in the front yard. Even if I could get electricity to it, it would have to be able to withstand being under water sometimes.

Wait what? I am slightly dumbfounded that does not seem up to code, there has to be an entry point into the house that has a on off valve it does not make sense to have to run outside to turn off your water. I have a valve outside my house too but its located in the sewers so not sure if thats what your talking about?

Well I guess you can always put it what should be your first entry point right before the water heater? Also these can go before sinks and bathroom pipes so it has multiple locations it can be installed if you dont want your main being turned off every time. That just means more sensors to buy though.
