Nuki Smart Lock and Homey presence
Homey presence helps Nuki devices to become even smarter.
For example: a standalone Smart Lock can be scheduled to lock the door every evening at 22.00. A Smart Lock driven by Homey can also lock the door every evening at 22.00 but only if all family members are at home.
Another example: A Smart Lock driven by Homey can automatically lock the door when the last family member left home.
But, can Nuki devices also help Homey presence perform better? Yes, if presence in Homey adopts the proximity approach. Proximity is when a personal device (which can be associated with a specific person) is detected in the neighborhood of Homey.
- Homey can detect a beacon. A beacon is a small wearable device that repeatedly transmits the same Bluetooth Low Energy (BLE) signal at regular intervals.
- Homey can detect a smartphone connected to home Wi-Fi through network pings or TCP connections.
The proximity must be verified 24x7 and every now and then it can happen that Homey skips a beat (i.e. Homey marks a person as away because it missed a BLE advertisement or a network ping).
Here come the Nuki door sensor. Homey may assume that a proximity device is no longer nearby but this must be confirmed by the Nuki Smart Lock door sensor: if the door hasn’t been opened or closed in the last few minutes, no one could have left home!
Take a look at this flow:
In this flow there is a new condition card that allows checking if the contact alarm (the Smart Lock door sensor) changed its state in the last n
seconds. If this condition is met, we can safely assume that someone has really left home.
This flow card is available in the new version of Nuki Direct that will be deployed next week.
