    Hidden Installation (Under the visual with the drill)

    Unlike other sensors that install in plain sight, Hidden Wi-Fi Door Sensor is installed inside your door or door frame. The end result is a sensor with practically zero visual intrusion.

    Feature Door2

    Now You See It, Now You Don't

    Nothing makes your home smarter than adding sensors; but even our unobtrusive Insteon Open/Close Sensor can be too large for certain decors and locations. That's why we've created the Hidden Door Sensor. Instead of mounting to the surface of your door, Hidden Door Sensor is installed inside the door frame or even the door itself.

    Feature Drill2

    Installation - Power Tool Time

    Using a 3/4" drill bit, simply drill a hole into your door frame along the hinge-side of your door, slide Hidden Door Sensor in and secure it with the included screw. We've included a spacer to ensure that your sensor will activate every time your door is opened or closed.

    Feature Hinge2

    Equal Opportunity Installation

    Wood doors are easy; almost every home owner has the tools necessary to drill through a wooden door frame or door. But what if your door or door frame is made of metal? Hidden Door Sensor is just as easy to install in the door itself along the hinge-side of the door. If both your door and door frame are metal, we suggest using Insteon Open/Close Sensor instead.

    Works for me Review by Donald
    Works for me

    Installed these in three closet doors linked to dimmer switches since wife often forgets to turn the lights off. They have all worked well with the linked Insteon dimmer switches. Across the three, battery life has been 10 to 12 months. Batteries are easy to install (just remove it, replace the battery, and reinstall it) and no re-linking was required. While I do have an extensively used ISY-994i controller, I've had no reason to attempt any linking of these to the controller unit so I can't speak to that.

    Great door sensor - dosen't work with every switch Review by Bob
    Great door sensor - dosen't work with every switch

    Recently purchased a door sensor and non dimmer switch for my pantry. Why waste a dimmer switch on a light that I want on or off! Installed the switch and decided to make sure the door sensor would work before I drilled a big hole in the door frame. Spent an hour trying to get the door sensor to work with the luck. Checked you tube, Insteon home page, everything I could think of to find out why this isn't working. Finally I tried pairing it with a dimmer switch I have and BING GO, it worked. So it appears that this door sensor only works with dimmer switches and dimmer plug in modules. Now I have 3 non dimming switches that are of no use to me. Reached out to Insteon via email 3 days ago and have yet to hear back from them. If this is truly the case, it should be noted that the door sensor will not work with (X) devices, If I'm doing something wrong on my end I would like to know what it is. Good Products, will continue to purchase, just didn't see this coming.

    Hello Robert. This works with all dual band Insteon devices.

    Works as advertised

    I found this was easy to install and add to my insteon system. Now I get an alert when my front door is opened. When received, the battery contact was bent, but easy to bend back to make contact.

    Discreet and works flawlessly. Put in 3 doors, and they all work perfect. Opening the door even slightly, triggers the sensor every time. Excellent product.

    4 year review - not perfect Review by Rob
    4 year review - not perfect

    I have about 10 of these on our doors and have used them for about 4 years.

    PRO: like stated, they're small, easy to install, and hidden. this also means that signal strength is lower and they have smaller batteries.

    CONS: I'm going nuts replacing batteries for these and my window sensors. With ~40 of them installed in our home, I'm replacing batteries every 3-6 months for frequently used items. I can't use rechargeables or they only last half as long. Buying new batteries is a pain, but even more is writing monitoring reports to check status and the easy but frequent labor of changing them all the time.

    Also: after my ISY system reboots, the status for all my doors is blank. I have to operate the door to get a status. If I try to refresh the status, it turns blank again. So if a sensor is somewhat unreliable, I can't query it again to make sure.

    Some newer zWave devices are advertising 3 year or 10 year batteries, others are combining with additional sensors. If I had to chose between replacing 400-600 batteries for my 40 devices over a 10 year period vs. just once, I would have chosen differently.

    Seems that Insteon has had a lot of devices and modules out for some time with no refreshes. They're getting competition - good! But they need to keep up.

    Repurposed Review by Robert

    I have two, one is on my backyard gate and turns on yard lights when entering. The second is an interface to my DSC alarm panel. I used a relay, voltage regulator, resistors to convert it to a DSC to Insteon interface. It now turns on a set of insteon lights if the panel goes into alarm. All the parts fit in place of the battery and it is wired into my alarm panel. These have worked well.

    Works well, but a few gotcha's Review by Paul
    Works well, but a few gotcha's

    Expecting to put in several of these, I first started with the door I cared about the least in case I destroyed the drilling. It went fairly well, but here are the initial issues.

    First, The It should really be in frame on the door hinge side. This will keep the stress on the push button to a minimum as the hinge side basically presses in and out from the top not pushing the button in from the side..

    Second, It should be high up so if the door is opened in the rain, it is out of the way.

    Now on to the issues...
    When installing in the frame, I was forced to drill into cement as my basement door is mounted into the 8' cement pour. Try drilling 2" into the cement and have a load of fun!

    When reaching my first 'House' door , I drilled into the side with the hinges and up high to avoid the rain. I started by centering the drill and as soon as I got past the frame the drill forced itself into the plasterboard wall. This is because past the frame on an outside wall, the 2x3 support may not be in align with the door frame at the drill point. So you can imagine it you start drilling and now somehow you have to cut a 1/2 of a hole D like an upside down D as the balance was behind the plaster board. So I had to drill many small holes and increase until I could clean out the necessary 3/4 diameter hold needed at the proper depth.

    Next I tackled the front door and this was not and is still not a good solution. Since my front door has see through glass designs on both sides of a 36" door, I could not dill into the frame on either side. This left only the top. So I tried to get the hole as close to the hinge side as possible, but not to close where a person could get in without triggering the switch.

    This worked, but no matter how I adjust the height - with their spacer or my washers, the switch has this 'bang' or 'bump' when the door closes. The push movement is not good when pushing from the side as would happen with a "top" or "not hinged side" mount.

    So the slant on the button that closes will eventually get an indent and the door will close poorly over time. You can try as I di to grease just the plunger a bit. But this is not a good solution.

    Also I could not use the switch that is not hidden as this is a very visible front entrance and anything around the door molding would take away from the glass designs.

    Over all this device works very well but it is too long and requires too deep a hold to set.

    I currently have 3 of these internal hidden units and 1 external open close on the sliding door. That is hidden by the curtains - so that works well and the size is good.

    Stopped Working Correctly After 3 months Review by Cameron
    Stopped Working Correctly After 3 months

    I have owned this sensor for a about 4 months and it is completely inaccurate now. Half the time it says the door is open now when it hasn't opened. The status used to be right when I first installed it, but it seems to just change randomly now. Can't really rely on it anymore.
