The Freetronics dot matrix displays are very versatile. Toby Robb has put together a great video showing how he has set up the display to read messages from MQTT. If your home automation system incorporates MQTT this could be a great way to display information about your home.
If you are looking for an LED dot matrix display why not check out the Freetronics range of displays. They are simple to use, yet very bright for indoor and outdoor situations. Available in various colours, the 32 x 16 LED matrix can display text and graphics easily, and can be daisy-chained together for extended displays.
