Please check my RuuviTag listener - notifier at https://github.com/srados/blistener
I built this application to listen to RuuviTags and send notifications if a sensor temperatures enter/exit predefined Alert states (set in the app configuration file).
One of goals of this application is to keep things simple. It’s written in Go, so it compiles to a single binary which can be easily deployed on several architectures.
This initial version sends notifications to email addresses set in the configuration file.
I have a couple more features planned for the future like sending alerts/reports to Matrix chat server, so stay tuned for status updates.
