I recently installed ST Arrival Sensors in my home to keep track of when my kids arrive back from school. The idea is simple yet brilliant—placing a sensor in their backpacks allows me to monitor their arrival without needing to constantly check my phone. However, I’ve encountered an intriguing issue that I’m hoping the community can help me solve.
The problem arises when the sensors occasionally trigger a ‘departure’ followed by an ‘arrival’ event, even though the backpacks haven’t moved. This happens sporadically, but it’s enough to be quite annoying. What’s more concerning is that these false triggers can sometimes cause my Smart Home Monitor (SHM) to disarm when I’m away from home, which is a security risk I’d rather avoid.
I’ve done some troubleshooting and noticed a few things:
- The sensors are placed near the hub, so signal strength isn’t the issue.
- They work flawlessly when detecting real arrivals, with impressive range.
- The false triggers happen almost instantly, with no delay between departure and arrival events.
I’m at a loss as to what’s causing this behavior. The sensors are functioning perfectly in every other aspect, so it’s puzzling why they’d misfire like this. My initial thought is that there might be some environmental factor or interference I haven’t accounted for, but I’ve yet to identify what that could be.
To mitigate the issue, I’d love to find a way to set up rules that prevent the sensors from triggering unless they’ve been away for a certain period of time. For example, if an arrival can only be detected after the sensor has been gone for at least 10 minutes, it would solve the problem entirely. I’m not sure if this is possible with the current setup, but I’m hopeful the community might have some insights or workarounds.
If anyone has experienced similar issues or has suggestions on how to address this, I’d be incredibly grateful for your input. Let’s see if we can crack this mystery together!
