SimpliSafeEntry Sensor - Window and Door Protection - Compatible with Gen 3 Home Security System

I love Simpli Safe. Their alarm system is great. Easy to install, use, and expand as needed. It has been 100 percent reliable for several years now. Highly recommend this system and the company.

Good product and price was right.

The price was right!! But it’s difficult to open the sensor to changed the battery

Added to my system..

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 doesn’t work with Apple.Back to installation, don’t 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 hasn’t 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 Pro’s, and Apple Watch 4. The phone app is just OK, but slow compared to other apps. There is no iPad app. You’re 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 doesn’t 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 don’t 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.
