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

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 variables:

• display_options (Requires) array: List of details to monitor. Defaults is memory_free.
  • 'temperature'
  • 'humidity'
  • 'pressure'

{% linkable_title Installation instruction for the All-In-One installer and HASSbian %}

Here are the steps to make the Sense HAT sensor work with a virtual environment.

Install SenseHAT package. Switch to the homeassistant_venv directory and activate the virtual environment.

$ sudo su -s /bin/bash homeassistant
$ source /srv/homeassistant/homeassistant_venv/bin/activate

Install the sense-hat module.

$ pip3 install sense-hat

Please be patient, this will take a long while...

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 the RTIMU Python module:

$ pip3 install rtimulib

Add symlink to RTIMU in homeassistant_venv directory. Create a symlink using the following command:

$ ln -s /usr/lib/python3/dist-packages/RTIMU.cpython-34m-arm-linux-gnueabihf.so /srv/homeassistant/homeassistant_venv/lib/python3.4/

Add homeassistant user to the input and the i2c groups.

$ sudo addgroup homeassistant input
$ sudo addgroup homeassistant i2c

Reboot Raspberry Pi to apply changes.

$ sudo reboot

{% linkable_title Customizing the Sense HAT data %}

To format the sensor values, add the following to your sensor entry in your configuration.yaml file.

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

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

Add the following to your customize section to set friendly names & icons for the values.

# 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 for your Sense HAT details by adding the following to your groups section.

# 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 a group (Kitchen for example)

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