Getting alerts when home devices join the network
A small server running Docker is being used to detect devices connected to a home LAN. already finds devices on the network, but it does not easily send an alert every time a chosen device connects or disconnects. The goal is to identify a known device by its and receive a notification when that device appears or leaves.
ntfy has already been set up and tested by hand, so the missing part is the automatic trigger from the network to the notification service. A better trigger setup or a different tool may be needed for this use case.
Key points
- can detect devices on the LAN, but alert triggers are the hard part.
- The desired rule is based on a known device’s .
- ntfy work manually, but need automatic triggering.
- The setup is meant for a Docker-based environment.
- owners can use the same idea for home presence and network .
