I updated firmware using the Konnected app so that I could invert the sense of the water sensors. After the update, I no longer can find the warning_beep entity (in Home Assistant), nor does it show up in the web page for the Alarm Panel Pro device in the ESPHome integration.
I also am no longer able to control ALRM1 or ALRM2.
Here is how I configured the Konnected app to generate the new firmware:
All of the sensors are working perfectly, but I cannot activate the siren (which is connected to ALRM1).
For the benefit of anyone who stumbles on this post: When you are configuring new firmware, do not assume as I did that you can ignore ALRM1, ALRM2, and OUT1 because you are not making any changes to those outputs. You need to open the expander and enable the outputs or they will be disabled in the new firmware.
