+
+The **Bosch Alarm Panel** {% term integration %} allows you to connect your [Bosch Alarm Panel](https://www.boschsecurity.com) to Home Assistant in order to control and monitor your Bosch Alarm Panel.
+
+{% include integrations/config_flow.md %}
+
+Supported panels:
+
+- _Solution 2000/3000/4000_
+- B Series: _B3512/B4512/B5512/B6512_
+- G Series: _B8512G/B9512G_
+- _AMAX 2100/3000/4000_
+- _D7412GV4/D9412GV4_ [^1]
+
+[^1]: Firmware 2.0+
+
+## Provided entities
+
+The {% term entities %} are divided into four subdomains:
+
+- [AlarmControlPanel](#alarm-control-panel)
+- [BinarySensor](#binary-sensor)
+- [Sensor](#sensor)
+- [Switch](#switch)
+- [Lock](#lock)
+
+## Alarm Control Panel
+
+This integration adds an Alarm Control Panel device for each configured area, with the ability to issue arm/disarm commands.
+This entity reports state (_disarmed_, _armed_away_, etc), and contains custom attributes _ready_to_arm_ (_no_|_home_|_away_), and a _faulted_points_ counter.
+
+## Binary Sensor
+
+A binary sensor is added for each point configured on your alarm.
+
+## Sensor
+
+Two sensors are added, one containing the history events from your panel, and another containing the current faults from it.
+The history itself is stored on a `history` attribute, as there is a limit to how much text a sensor can store in its state.
+
+## Switch
+
+A switch is added for each output configured on the panel. Note that for some panels, only outputs with the type set to "remote output" can be controlled via _Mode 2_ API.
+
+## Lock
+
+A lock is added for each configured door on your panel  (_Solution 4000_, _B Series_ and _G Series_ panels only).
+
+## Actions
+
+The integration provides the following actions.
+
+### Action: Set Panel Date & Time
+
+| Data attribute         | Optional | Description                                                                     |
+|------------------------|----------|---------------------------------------------------------------------------------|
+| `datetime`             | Yes      | The Date & Time to set. Defaults to the current date and time if it is not set. |
+
+## Authentication
+
+The primary means of authentication for the _Mode 2_ API is the _Automation_ passcode. It needs to be at least 10 characters long, and it is different from the _User_ code -- a shorter numeric pin used to arm/disarm the panel.
+The integration will prompt for the required passcodes, which depend on the panel type.
+
+| Panel | Code |
+| --- | --- |
+| Solution | User [^2] |
+| B Series | Automation |
+| G Series | Automation |
+| AMAX | Both |
+
+[^2]: The user needs to have the "master code functions" authority if you wish to interact with history events.
+
+⚠️ Since the _Mode 2_ automation user has "superuser" privileges, it bypasses the regularly-configured alarm pin: you will _not_ be prompted for a _User_ code when arming/disaming through the integration.
+The integration also supports (optionally) setting a Home Assistant-local pin to protect these operations -- it does not need to match any of the codes configured on the panel.
+
+## Removing the integration
+
+This integration follows standard integration removal. No extra steps are required.
