Frequently asked questions

Why Floor Sentry?

Installing a Floor Sentry with your new wood floor helps protect your investment. Wood flooring may be at risk of damage or catastrophic failure if exposed to unfriendly ambient conditions. This unwanted exposure can occur either from inside your home or building or from the underside of the flooring (what is often called the subfloor).

How Do I Use The 1-Year Warranty?

If for some reason the Floor Sentry fails, the best way to submit a warranty request is to contact our customer service to find the best solution for your replacement. To contact our customer service please email info@wagnermeters.com or call (800) 634-9961.

What Does Floor Sentry Measure?

The Floor Sentry operates directly inside your wood floor, monitoring temperature and relative humidity (RH).

Can I Customize Alerts?

Yes, you will need to use the Floor Sentry device with the Wagner Sentry app to customize and set preferred/recommended readings. If either the temperature or the RH falls outside your desired range for proper floor care and/or avoiding potential floor damage, the Floor Sentry alerts you automatically, delivering notifications wirelessly to your mobile device. You must be within Bluetooth range to receive Floor Sentry notifications.

How Many Floor Sentry’s Do I Need?

Place one Floor Sentry for every 1,000 square feet, and at least one on each story or level. If the floor has radiant heating zones, then install one Floor Sentry for each heating zone.

How Do I Connect to the Wagner Sentry App?

Step 1: Install the Floor Sentry in your wood flooring.

Step 2: Download the Wagner Sentry app from either the Apple App Store or Google Play.

Step 3: Open the app, give your Floor Sentry device its own unique name, adjust the default settings (as needed), click the Device Installed button on the Device Settings screen, and you are ready to begin monitoring temperature and RH at whatever frequency you desire.

Can I Install Floor Sentry Within Thin Wood Planks?

Wagner Meters does not recommend installation in boards with thicknesses less than ½ inch.

Easy to use

Husband and I are using this in our kitchen, and we like having some peace of mind that we'll be alerted in case of a water leak. It's small and fit well, was easy to install, and a preliminary test shows it will work effectively.

Great Potential Protection for My Floors

I'm just finishing installing my wood flooring in my house that I've been working on for weeks. Then I stumble upon this little gem and it couldn't have been better timing. Now I was able to install it before I finished sealing up the floors. Keep in mind that you'll need to "install" the sensor into the flooring. What I mean by that is you'll need to use a router to create a slot for the sensor to sit inside of on the bottom of one of the planks. Luckily I had a neighbor that I was able to borrow a router from, because that's not a tool that most people have. I would also recommend installing it on one of the boards that are closer to the end of the room. That way if there's any sort of issue, then at least you won't have to rip out the entire room to get to it. The sensor itself is supposed to last for 10 years, but only time will tell when it comes to that. So at least theoretically I have some peace of mind knowing that I can keep track of the temperature and relative humidity of my expensive flooring.

Easy to Use

Nice and simple and effective. Very easy to use and it works great doing exactly what it was designed to do. Nice product that in some situations could save a lot of hassle, trouble and money. :)

Great concept. Very simple setup. A couple concerns

This is a great idea to protect and monitor your floors. The only challenge is figuring out how and where to install it. They include detailed instructions (such as one unit every 2,000 ft2), but I would think installing it near the plumbing would be the ideal scenario (ie, near the kitchen sink or dishwasher). The app is super easy - installed in seconds, immediately paired with the device, and I was reading my stats within two minutes of unboxing.It's got a 10 year battery life. Depending on your situation, if you can reach the device you may be able to replace the battery (if the bluetooth is still working, that is). However, it's not intended to replace the battery, this thing is sealed up, it will require some minor surgery to get to the battery.My first concern - this arrived turned on. There is no tab over the battery compartment to pull out. I don't know the assembly date, but did this shorten the life of the battery?Another concern - I hate having one more app on my phone for one more smart thing. They are definitely correct that this could save tens of thousands of dollars. It's primary goal is to alert you to long term humidity problems by monitoring humidity & temperature. But I suspect it could conceivably alert you to a fire, a water leak, and many other things. But I wish it could just send me a text or email, or tie into the Smart Life app. Also, I typically have my bluetooth turned off while in the house, meaning that it wouldn't be able to alert me to an acute situation (like a leak or fire).My final concern is installation. The instructions only cover one scenario - new hardwood install, and routing a cavity into the hardwood and placing the device inside the cavity above your underlayment. But surely there are ways to retrofit this onto existing floors, and ways to use it without routing out a cavity. If you're interested in doing this, I would encourage you to request advice about your specific situation.
