android-mqtt-alarm-panel | Android Alarm Panel for Home Assistant

You can clone the repository and compile the APK using Android Studio, then side load the APK file onto your device. You can also side load the built APK from the release section or just install the application from the Google Play Store.
Alarm Panel should work with any MQTT broker and does not require Home Assistant. If you are using Home Assistant, then you will want to use the Manual MQTT component and the built in MQTT integration for your setup.
Setup Home Assistant
Configure the MQTT service, note the broker address and username/password if applicable.
Add the MQTT Manual Home Assistant component to your configuration with the default settings.
Add any sensors (like Zwave door sensors or sirens) and configure automations to trigger the alarm.
Under the settings (gear icon) enter the MQTT information, that you configured in your MQTT service. This might include a username and password. If you are not using SSL, just enter the IP address of your broker like 192.168.1.1. You enter the port and credentials in separate fields. The alarm will try to connect using TCP, unless you enter HTTP/HTTPS in front of the IP address like http://192.168.1.1. However, for most MQTT brokers, using TCP is fine. Depending on your MQTT broker, after you setup mqtt, you may not receive the "initial" state or message from the broker. This may mean that features, that depend on MQTT such as weather, sun and the alarm state, may initially be in their default or disabled states until data is received. Alarm panel subscribes to MQTT state changes published from the remote alarm system. The default state topic is home/alarm and can be changed in the settings. Here is a list of state values and their descriptions, that the application can handle. Alarm Panel can send to the server commands for different alarm states. The MQTT Broker listens to these commands to update the state of alarm. The default command topic is home/alarm/set, which can be changed in the settings. Here is a list of commands sent from the application to the MQTT broker. | Command | Description | | ------- | ----------- | | ARM_AWAY | Arm the alarm in mode armed_away. | | ARM_HOME | Arm the alarm in mode armed_home. | | ARM_NIGHT | Arm the alarm in mode armed_night. | | ARM_CUSTOM_BYPASS | Arm the alarm in mode armed_custom_bypass. | | DISARM | Disarm the alarm. | | PANIC | Alarm panic button pressed. |.
Note not all states are supported by the HA Manual MQTT component and would need to manually handled. Sending additional states is optional and the alarm panel will function without the additional states arm_away, arm_home, arm_night, arm_custom_bypass.
Note: not all commands are supported by the Home Asssistant Manual MQTT component. You will need to listen to the incoming command and handle the command manually, using an automation or blueprint to handle modes ARM_NIGHT, ARM_CUSTOM_BYPASS, PANIC. If you are using your own MQTT broker, you can optionally handle these commands.
Example payload on the state topic with a delay (Consider the scenario where the user sets the alarm to arm_away and the application displays a countdown of how much time before alarm is armed so the user can exit the home):
Optionally without the delay value:
