LANnouncer runs in the background, listening on LAN (local), SMS or GCM (Google Cloud Messaging) to announce events from your home automation system. LANnouncer supports TTS (text-to-speech), so that events can be fully spoken, plus a few basic alarms, strobes and text notifications. It can also take photos or prepare them from local IP cameras.

Alone, LANnouncer isn't very valuable. But with the help of a Home Automation System, IFTTT recipes or scripts, it can bring events to life.

Google has deprecated Google Cloud Messaging. This version moves to Firebase Messaging and fixes a few issues caused by other recent Google API changes.

Previous versions of LANNouncer will stop working soon, probably around end-of-May 2019, when Google shuts down GCM. Consequently, this is a mandatory update.

If you have Premium, ensure "Enable GCM" (still called that) is on, rather than "No IFTTT Support", or the additional slots will not display.
