Entry Sensors are a reliable choice
**SimpliSafe Entry Sensor - Window and Door Protection** As someone who takes home security seriously, I decided to expand my SimpliSafe security system with additional Entry Sensors for my doors and windows. I was looking for reliable and easy-to-install sensors that would integrate seamlessly with my existing SimpliSafe setup. **What I Like:** - **Easy Installation**: The installation process for these sensors is incredibly straightforward. They come with adhesive strips that make it easy to attach the sensor to any door or window frame without needing any tools. The entire setup takes just a few minutes, which is perfect if youโre not particularly handy. - **Seamless Integration**: These sensors integrate perfectly with the SimpliSafe system. Once installed, they immediately sync with the base station, and you can manage them through the SimpliSafe app. The integration is smooth and hassle-free, and the sensors work reliably with the system. - **Compact Design**: The sensors are small and discreet, so they donโt stand out or detract from the appearance of your doors or windows. The low-profile design is a big plus for maintaining the aesthetic of your home while still enhancing security. - **Reliable Performance**: The sensors have proven to be very reliable. They trigger alerts immediately when a door or window is opened, providing peace of mind that your home is being monitored effectively. Thereโs no noticeable delay, and the connection with the base station remains strong. **What I Donโt Like:** - **Adhesive Issues**: While the adhesive is convenient for installation, it might not hold up as well over time, especially in areas with high humidity or temperature fluctuations. In some cases, you might need to reinforce the sensors with additional adhesive or screws to ensure they stay in place. - **Price**: The sensors are a bit on the expensive side, especially if you need multiple units to cover all your entry points. While the quality and reliability justify the cost, it can add up quickly if youโre securing a larger home. - **Limited Customization**: The sensors donโt offer much in terms of customization. They work as intended, but it would be nice to have more options for sensitivity settings or other adjustments to better suit different environments. **Bottom Line:** The SimpliSafe Entry Sensor is a must-have addition for anyone looking to enhance their home security system. Itโs easy to install, integrates seamlessly with the SimpliSafe ecosystem, and offers reliable performance. While the adhesive might not hold up under all conditions and the cost can add up, the peace of mind provided by these sensors makes them a worthwhile investment. If youโre expanding your SimpliSafe system or setting it up for the first time, these Entry Sensors are a reliable choice for protecting your homeโs doors and windows.

Great system and customer service, installation is so easy.
So far so good. I use these on all doors and windows so if someone breaks into the house, either these will sound off or the motion sensors will (also by SimpliSafe). Good customer service when I've needed to call. We've been using SimpliSafe for a few years, and even have their subscription plan. Husband set the alarm off this morning, forgot to turn it off, and it was one of these new sensors that is on the front door. Installation was easy, don't have to have them touching, just within a 2" area. Most of ours are about 1" and work perfectly. I was able to disarm the system once hubs set it off by using the remote. Good system and we're happy to have it.

Not as simple as it would seem and no Apple HomeKit support
Not as simple as it claims AND NO APPLE HOMEKIT SUPPORT. After a lot of research, we made the wrong decision and went with SimpliSafe. The videos and online manuals made setup appear simple. We purchased one keypad , 8 entry sensors, motion sensor, doorbell, door lock, and camera. Much of it was very simple to set up and some of it even very impressive. However, it is not even close to being as easy as they make it look. If your able to use a phone app, it is much simpler to setup than naming your devices with the archaic input on the keypad. Before I continue, let me reiterate that SimpliSafe does not work with HomeKit (Siri) although when we ordered our system this was supposed to be coming. Now everything I read says that basically Apple and SimpliSafe were not able to come to an agreement and there is no integration planned in the future (confirmed by tech support). This would have been a deal breaker as I would have never went with a system that doesnโt work with Apple. Back to installation, donโt expect a couple of hours to install it. Plan on a full day. The lock is not nearly as intuitive as it seems to install and none of the adapters were exactly what the instructions said we needed for our brand new construction townhouse. We picked the one that looked most like the suggested one and luckily it worked. You are actually replacing a physical deadbolt and this can take some time. The doorbell was very problematic. It repeatedly failed to connect to WiFi even though it is less than 8 feet from a repeater. The trouble shooter only offered the option of adding a repeater which we already had and was well within range. After less than two weeks the doorbell lost connectivity for no apparent reason. SimpliSafe support was very helpful even though they talk to you like you have no technology smarts at all, which is not my case. After walking me through a reset (tiny pin hole inside doorbell) that is not mentioned in any documentation I could find, we were able to get the doorbell back online and it has functioned correctly now for several weeks. Latest is that the camera has now lost WiFi connection even though the camera hasnโt moved and nothing has changed with our WiFi. After three tries to add the camera, it refuses to join the network. Again it has a very strong WiFi signal. Another call to customer support is going to be required to get the camera back online. Finally, the apps. We have the apps installed on an iPhone X, two iPad Proโs, and Apple Watch 4. The phone app is just OK, but slow compared to other apps. There is no iPad app. Youโre stuck with downloading the iPhone app meaning no horizontal use. Very disappointing. When the doorbell rings, I would expect the camera to automatically pop up on my phone. Nope. You get a notification and by the time the app opens and you can look at the camera, they are already gone. The Apple Watch app is totally worthless. It simply doesnโt work. Most of the time when you tap it is starts refreshing indefinitely. The couple of times that it did finish refreshing, the status of the alarm was totally wrong even though the phone had the accurate state of the alarm. Do your research and donโt believe all the recommendations that SimpliSafe supposedly has. There are several other security systems that I have send discovered, or are newer, that promise a better experience and Apple HomeKit integration. We use a different system in our vacation home that is far superior to SimpliSafe.

Good Product
I recently added the SimpliSafe Entry Sensor - Window and Door Protection to my home security system, and I have to say, it has done a great job. The sensor is easy to install and works seamlessly with my SimpliSafe system. The sensor is a perfect solution for window and door protection, and I appreciate the added security it provides. It is a small and discreet sensor that blends well with my home's decor, so it doesn't look out of place. I also appreciate that the sensor comes with a set of adhesive strips and screws, making it easy to install wherever I need it. The SimpliSafe Entry Sensor is incredibly responsive and detects any movement or opening of the door or window it is attached to. I receive notifications on my phone immediately when the sensor is triggered, which gives me peace of mind knowing that my home is secure.

Easy Add to a Simply Safe System
Very easy to add this sensor to a Simply Safe home alarm system. This uses a common 2032 coin battery that is cheap and available everywhere. The magnet does not need to be as close to the base as shown in the product photo. While not quite as sensitive as a professional-grade double balanced sensor, the extra range provides great installation flexibility. The sensor will work on most doors and double-hung windows. It should work on most in-swing casement windows. The base has an indicator LED that flashes once for OPEN and twice for CLOSED. This makes the sensor super easy to verify the installation before sticking the sensor to your door or window. Recommended.
