-
-This integration is deprecated and will be removed in Home Assistant Core 2022.4.
-
-For more information see: [Architectural Decision Record 0019](https://github.com/home-assistant/architecture/blob/master/adr/0019-GPIO.md).
-
-</div>
-
-There is currently support for the following device types within Home Assistant:
-
-- [Light](#light)
-- [Sensor](#sensor)
-
-## Light
-
-The `sensehat` light platform lets you control the [Sense HAT](https://www.raspberrypi.org/products/sense-hat/) board's 8x8 RGB LED matrix on your Raspberry Pi from within Home Assistant.
-
-To add `sensehat` light to your installation, add the following to your `configuration.yaml` file:
-
-```yaml
-# Example configuration.yaml entry
-light:
-  - platform: sensehat
-```
-
-## Sensor
-
-The `sensehat` sensor platform allows you to display information collected by a [Sense HAT](https://www.raspberrypi.org/products/sense-hat/) add-on board for Raspberry Pi.
-
-To add this platform to your installation, add the following to your `configuration.yaml` file:
-
-```yaml
-# Example configuration.yaml entry
-sensor:
-  - platform: sensehat
-    display_options:
-      - temperature
-      - humidity
-      - pressure
-```
-
-{% configuration %}
-display_options:
-  description: List of details to monitor.
-  required: true
-  default: "`memory_free`"
-  type: list
-  keys:
-    temperature:
-      description: Temperature
-    humidity:
-      description: Humidity
-    pressure:
-      description: Pressure
-name:
-  description: Change the name of the sensor, for in the frontend.
-  required: false
-  type: string
-is_hat_attached:
-  description: Declaring that the SenseHAT _is_ physically on the Raspberry Pi.
-  required: false
-  default: true
-  type: boolean
-{% endconfiguration %}
-
-### Customizing the Sense HAT data
-
-#### Format the sensor values
-
-Add the following to your `sensor`:
-
-{% raw %}
-
-```yaml
-# Example configuration.yaml entry
-sensor:
-  - platform: sensehat
-    display_options:
-        - temperature
-        - humidity
-        - pressure
-
-  - platform: template
-    sensors:
-      sensehat_temperature:
-        value_template: "{{ states('sensor.temperature') | round(1) }}"
-        unit_of_measurement: "°C"
-      sensehat_pressure:
-        value_template: "{{ states('sensor.pressure') | round(1) }}"
-        unit_of_measurement: "mb"
-      sensehat_humidity:
-        value_template: "{{ states('sensor.humidity') | round(1) }}"
-        unit_of_measurement: "%"
-```
-
-{% endraw %}
-
-#### Give the values friendly names & icons
-
-Add the following to your `customize`:
-
-```yaml
-# Example configuration.yaml entry
-customize:
-  sensor.sensehat_temperature:
-    icon: mdi:thermometer
-    friendly_name: "Temperature"
-  sensor.sensehat_humidity:
-    icon: mdi:weather-rainy
-    friendly_name: "Humidity"
-  sensor.sensehat_pressure:
-    icon: mdi:gauge
-    friendly_name: "Pressure"
-```
-
-#### Create a group
-
-Add the following to your `groups`:
-
-```yaml
-# Example configuration.yaml entry
-group:
-  sense_hat:
-    name: Sense HAT
-    entities:
-      - sensor.sensehat_temperature
-      - sensor.sensehat_humidity
-      - sensor.sensehat_pressure
-```
-
-Add the sense_hat group (_Kitchen for example_)
-
-```yaml
-# Example configuration.yaml entry
-group:
-  kitchen:
-    - group.sense_hat
-```
-
-### Directions for installing on Raspberry Pi Raspbian Based installation:
-
-Here are the steps to make the _SenseHAT_ sensor work _successfully_ with the virtual environment versions.
-
-#### Install SenseHAT package to _homeassistant_venv_
-
-```bash
-# switch to the homeassistant_venv environment
-sudo -u homeassistant -H -s
-source /srv/homeassistant/homeassistant_venv/bin/activate
-
-# install the sense-hat lib
-pip3 install sense-hat
-# be patient, this will take a long while
-```
-
-#### Return to `pi`
-
-Type `exit` to quit out of the _homeassistant_venv_ back to your `pi` environment.
-
-As all of the following steps should be under the `pi` user environment.
-
-#### Install _RTIMU_
-
-```bash
-# pi user environment: Install RTIMU
-pip3 install rtimulib
-
-# pi user environment: Add _homeassistant_ user to the _input_, _video_ and the _i2c_ groups
-sudo addgroup homeassistant input
-sudo addgroup homeassistant i2c
-sudo addgroup homeassistant video
-
-# HA environment: Add symlink to RTIMU
-ln -s /usr/lib/python3/dist-packages/RTIMU.cpython-35m-arm-linux-gnueabihf.so /srv/homeassistant/lib/python3.5/site-packages/
-
-# pi user environment: Reboot Raspberry Pi to apply changes
-sudo reboot
-```
-
-Unfortunately enabling the SenseHAT Sensor integration for a Virtual Environment install of Home Assistant fails with errors.
-_(The Raspberry Pi All-In-One installer run Home Assistant in a virtual environment)._
-These issues have been discussed in the repository issue [#5093](https://github.com/home-assistant/home-assistant/issues/5093)
-
-This fix has been tested with a clean install of:
-
-* [Raspbian Jessie - version January 2017](https://downloads.raspberrypi.org/raspbian/images/raspbian-2017-01-10/)
-
-and
-
-* Home Assistant 0.37.1
-
-For setting up the Sense HAT's RGB LED matrix as lights within Home Assistant, please see the [Sense HAT light component](#light).
