I just bought the arrival sensor because my iPhone 7 plus only works from time to time. I used to use iphone to automatically execute [I’m Back] and [Goodbye]. Now I have both iPhone and arrival sensor connected with SmartThings. This happened last night I woke up at 1:48 am, all my lights are open, garage door and locks. I got panic for a second, and then I checked the smartthings log, it turns out [I’m Back] was triggered at 1:38 am. Here is a bit of background info, I usually leave the arrival sensor in my car and leave my car in my garage. As you can see on the screenshot, the arrival sensor got disconnected (offline) at 1:10 am, and re-connected at 1:38 am [online] which triggered [I’m Back]. I urge smartthing staff to take look at this straight behavior, it puts my family under a huge risk of personal safety. Right now I have remove the Arrival Sensor from any routines for safety concerns, but I still keep it in smartthing in case someone wants to see any logs. ![ArrivalSensorGoneWrong](https://global.discourse-cdn.com/smartthings/original/3X/b/d/bd1683b7e044e297435ffcfd5ee0c9ad8daa7461.PNG) ![Log](https://global.discourse-cdn.com/smartthings/original/3X/8/b/8b1c862379ee175c51c4c47719f0382b6aa46529.jpg) ---

My greatest suggestion is to use Life360. Its simple and works across all device platforms. I haven’t had it fail yet. ---

This can happen with any single presence method that you use with SmartThings. The Usual solution is to require that two things show that you are away before you are actually marked as away. See the following discussion thread > [@Extremely Scary Bug! (Lost internet causes away/arrival sequence to fire)](https://community.smartthings.com/t/extremely-scary-bug-lost-internet-causes-away-arrival-sequence-to-fire/92488/): > > Hi all, I woke up today to a notification saying SmartThings had unlocked my connected door lock at ~3:55am. After momentarily panicking and checking the house, I came to realize what had happened. Somehow, either the internet had gone offline, my router had restarted, or the SmartThings hub itself had. Whenever it came back online, it ‘detected’ the presence of my SmartThings [arrival sensor](https://shop.smartthings.com/products/samsung-smartthings-arrival-sensor) and unlocked the door per my automation rule. I’m still investigating, but if it was the internet, this means that all somebody has to do is unplug your uplink to the internet and plug it back in (often the ISP cables are just sitting outside your house), and if you have an arrival sensor, the door would unlock. Similarly, if it was the router/hub, if an attacker can temporarily cut your power, they … ---

Thank you for fast reply, I will definitely give it a good try. ---

You need to set the routines with locks to not run in Night mode as an extra level of safety. ---

I suggest disabling automated arrival sensor unlocking when in “Night” or “Home” - only allow unlocking when a sensor appears while the mode is “Away.” If you come home while some one else is home/asleep, it’s simple enough to run “I’m Back!” From your phone or your iWatch… ---

I will give a try for the dual devices approch. I have a skybell HD in place which covers my driveway. However, I haven’t had much luck using the SmartApp to control anything by motion or button press. Right now, I link Skybell with IFTTT to turn on front porch light. ---

I still can’t believe people automate unlocking or opening doors. I am not planning to get any smart locks or door openers. There are other posts here about people coming home to wide open doors. Pushing garage door opener button is not that difficult that I would ever need to automate it. Want to turn on some lights when you get home, fine. ---

There are other posts here about people coming home to wide open doors. Pushing garage door opener button is not that difficult that I would ever need to automate it. Want to turn on some lights when you get home, fine. I understand the concern, and it’s definitely something you need to think through. But as long as you have a couple of conditions on it, you should greatly reduce any possible problems. In my case, I am quadriparetic and I cannot physically unlock the door, so I need an automation for that. As mentioned in the thread I linked to above, I eventually went to having a two device solution and that has worked very well for me. 🕶 Other people do other combinations of conditions. It’s not a matter of choosing one particular device, though. For some people, phone presence works great and the zigbee presence sensor doesn’t work, often because there’s a neighbor with boosted Wi-Fi which isn’t something you can do anything about. For other people, phone presence is unreliable, but the zigbee sensor works well. > [@FAQ: The Many Ways of Detecting Presence (2020)](https://community.smartthings.com/t/faq-the-many-ways-of-detecting-presence/51563): > > Presence, regardless of the device you use, is one of those features that works great for some people, not at all for other people, and is randomly flaky for still others. It’s very much affected by local conditions. So some people will find that phone presence works much better than the SmartThings-branded presence sensor. Other people will find the reverse. Still other people, myself included, find that they have to use a combination of two devices in order to get reliable presence indication. So if this feature tends to work differently for different people, where do you start? 1. Using a Smart Phone as a Presence Indicator Well, since most people who have SmartThings have a smart phone, it’s worth starting there. This method has changed significantly in the change fro… But when it comes to unlocking your doors, personally, I would not rely on any single condition. I always combine a couple. But of course if it worries you, there’s no problem with not automating it at all. Different things work for different people. 🕶 ---

For myself, I use two form of presence to trigger locks. I use Life360 app on my phone and a SmartThings presence sensor arriving as a dual device trigger.
