The lacracrosseview integration sees the Lacrosse C82929 as a temperature and humidity sensor, which is great, and it works right out of the box.
The La Crosse View phone app can also control the clock, and uses the same cloud hosted service and protocol as what we’re already using for the sensor logic.
I’ve done some work reverse engineering the ability to set the alarm, arm/disarm the alarm, and to send “text streams” to be displayed on the clock. With this work already completed, seems like a breeze to add more functionality to the lacrosseview integration.
Potential uses: Change alarm time based on traffic or weather! Display a message on the bedside clock based on any HA data…
