Use User’s Geo Location for Smart Control
There are some products on the market of smart thermostats/controllers that rely on knowing the user Geo Location to act “smart” – is this really smart?
When user is at given location there are several methods to figure it out:
Active:
- Pinging an IP address presence
- Checking current WiFi network name
- Using arping to check mac address presence
Passive:
- Listening for specific packets
All above are good if you do not need an extra time to react and that’s the problem. You can shutdown all the lights when no one is present.
