GROHE Sense Guard also monitors changes in temperature and water pressure to help prevent frost damage. Grohe Sense Guard connects to your home WiFi network. In the case of a connectivity loss, GROHE Sense Guard continues to protect your home by shutting off water in the event a pipe burst occurs.

No longer do I need to worry about my house flooding due to a water line break or a slow leak. The app works great too. I can see my system temperature, water pressure, and daily water consumption. In the event of a power outage the valve stays open, so you still have water. Every night it tests for a slow water leak. The instructions state a professional installer is required for installation. I consider myself as such and proceeded with installation. The installation video on the manufacturers website really helped clear some stuff up for me. I had to ad a house filter and a shut off after the sense guard for maintenance. Pretty straight forward.

The Sense Guard Water Controller is a great concept, especially for people who live in areas prone to cold weather where pipes burst, but can also be used for older homes with older pipes prone to cracks. This product detects burst pipes, leakages, and frost risk. It really helps to have someone familiar with these types of products to do the installation. It was a challenge finding reputable installers to do the job. The water sensor works by an app on a smart device. If you dislike smart technology this product may not be the best sensor for you. Wi-Fi connection is required in order for this product to work properly. After going through the hassle of installing I felt it was not the best product for my household because we are not prone to pipe bursts although any home I suppose could be prone to pipe leakage. Again, it's a very good product, but highly recommended for homes in areas where extreme weather conditions causes water pipe issues. The app is very easy to use, and easy to install on any smart device. Product comes with a 2-year warranty. Sensors not included.

I had a leaky toilet on a rental unit which ended up reflecting on the water bill. This product prevents most of the water damage that could happen from a burst pipe or money being wasted from anything that simply leaks into the sewer. Allowing automatic or remote control of the water coming into the house gives me full control and peace of mind on my investment and is much easier than dealing with water damage and insurance companies. I got a plumber to install it and do a full test with me there. Had to connect the Sense Guard to Wi-Fi prior to installation to make sure it works to prevent removal / replacement in case of a faulty unit. Luckily I have a power outlet within reach as the system does need to be plugged in. The entire system is also reliant on Wireless to be available in order to be connected and managed through the app. However in case of a power outage, the water flow remains on. The Grohe UNDUS app is straight forward and has water On/Off, pressure, temp and consumption info available at my fingertips. No more can the town misrepresent the usage numbers! In case of a water issue multiple alerts can be activated and sent to the app, along with LED indicators and beeps sounding from the device. Overall, I am happy with the peace of mind that this product provides. I’m sure in the future these will become the norm and be a bit more affordable to the average consumer.

My neighbor has one and was able to detect he left the garden hose on and it alerted of higher than usual consumption, so I wanted to get something that would do that too. I travel for work and leave my house vacant a lot and can't shut off the water so I feel safer with this being installed so it alerts me if there's a leak so I don't come to a flooded house. The installation looks easy for a plumber, but I wouldn't try installing myself so I hired a plumber. It was worth getting it installed correctly. The app was easy to set up, but I don't know how to test it to see if a real leak will alert me, but I did notice the water consumption going up as we used the dishwasher and washing machine, so at least I know the app works fine.

Rated 5 out of 5 by from PEACE OF MIND! I live in a townhouse, so if our unit were to sustain water damage, our neighbors would most likely also be affected (we learned this first-hand when our neighbor's hot water tank leaked into our unit). Knowing any issue that arises is an iPhone alert away, is so comforting. I bought this along with the Sense Smart Water Sensor and I'm so happy with the new sense of security. We watched the installation video and are pretty handy, but I suggest hiring a plumber (our main water supply is adjacent to the water heater under the stairs, so that alone made it challenging). That additional expense aside, this is worth every penny. Not only does it detect fluctuations in water pressure, but frost, as well. Anyone who's ever had a burst pipe knows water seeks its own level and goes EVERYWHERE. This may seem pricey at first, but it's so insignificant compared to the cost involved in replacing sheetrock, flooring, furniture, etc. I highly suggest making this investment.

It really gives me the peace of mind because it constantly monitor my water, pressure, water temperature, daily consumption. The best of all, it detects frost and water leak, whether it is a line leak or a slow leak. They have a installation video on their website. I found it very helpful. And their app is pretty easy to use as well.

Rated 5 out of 5 by from Excellent for piece of mind! I have been using the GROHE Sense Guard Smart Water Controller for a couple of months now. I waited to review it, until I could adequately report on the features. We installed a bypass for the unit which I do recommend. The controller seems to work well and has a setting for usage which we have adjusted based on how much usage the home was expecting. The modifications to settings are made via an app which is easy to use. I did have an instance when I forgot to update the settings for a high use visitor and the water did turn off for them prematurely (though as settings required). The controller is great for possible leaks to avoid excessive damage of water running for hours, or days unnoticed. The instance when I forgot to change the setting, our guest was able to go to the unit and use the bypass to get water running normally. I later adjusted the settings via the app remotely and the unit was put back into work. The controller does what it sets out to do and does it well. The installing plumber agreed that it seems to be an excellent product and installation was easy. Know that an electric outlet is necessary nearby to the unit. Check the pick size for your configuration to confirm compatibility. We reduced from a one inch pipe to 3/4 inch with no noticeably loss in pressure. Thanks Grohe for an excellent product!

This sensor and controller monitors your normal water usage, and if there is a leak, the sensor detects it based on an abnormal water usage pattern, and then lets you know AND shuts off your water if there is a major leak. It’s worked well for me and sent me notifications a couple of times when a leaky toilet had a slow leak. The installation was not super easy, but that’s because I have galvanized rather than copper pipes. With copper, all you do is cut it and there are quick couplings (compression fittings). With galvanized pipes, we had to retrofit by cutting out a section of pipe and then add threads to install this unit.
