The sensehat sensor platform allows you to display information collected by a Sense HAT add-on board for Raspberry Pi.

{% linkable_title Configuration %}

To add this platform to your installation, add the following to your configuration.yaml file:

# 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 te 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 %}

{% linkable_title Customizing the Sense HAT data %}

Format the sensor values Add the following to your sensor:

{% raw %}

# Example configuration.yaml entry
sensor:
  - platform: sensehat
    display_options:
        - temperature
        - humidity
        - pressure

  - platform: template
    sensors:
      sensehat_temperature:
        value_template: '{{ states.sensor.temperature.state | round(1) }}'
        unit_of_measurement: '°C'
      sensehat_pressure:
        value_template: '{{ states.sensor.pressure.state | round(1) }}'
        unit_of_measurement: 'mb'
      sensehat_humidity:
        value_template: '{{ states.sensor.humidity.state | round(1) }}'
        unit_of_measurement: '%'

{% endraw %}

Give the values friendly names & icons Add the following to your customize:

# 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:

# 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)

# Example configuration.yaml entry
group:
  kitchen:
    - group.sense_hat

{% linkable_title Directions for installing on Raspberry Pi All-In-One installer and HASSbian: %}

Here are the steps to make the SenseHAT sensor work successfully with the virtual environment versions.

{% linkable_title Install SenseHAT package to homeassistant_venv %}

# 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

{% linkable_title 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.

{% linkable_title Install RTIMU %}

# 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 component for a Virtual Environment install of Home Assistant fails with errors. (The Raspberry Pi All-In-One installer and HASSbian both run Home Assistant in an virtual environment). These issues have been discussed in the repository issue #5093

This fix has been tested with a clean install of:

• Raspbian Jessie - version January 2017

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.
