Party Squasher continuously detects Wi-Fi signals from phones around the sensor and in real-time. But when a new person enters the room with their phone, their phone may not immediately emit a signal for us to detect. Don't worry! Give it 10 minutes and your device count will adjust to new people entering or exiting your space.
So long as it's plugged in with internet access, the Party Squasher sensor is continually scanning the detection range that you've configured in Location Settings. That way, we can immediately alert you if we detect a big wave of devices entering your home.
