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 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.
```bash
$ sudo su -s /bin/bash homeassistant
$ source /srv/homeassistant/homeassistant_venv/bin/activate
```
Install the `sense-hat` module.
```bash
$ 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](https://github.com/RPi-Distro/RTIMULib) Python module:
```bash
$ pip3 install rtimulib
```
Add symlink to RTIMU in `homeassistant_venv` directory. Create a symlink using the following command:
```bash
$ 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.
```bash
$ sudo addgroup homeassistant input
$ sudo addgroup homeassistant i2c
```
Reboot Raspberry Pi to apply changes.
```bash
$ 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.
```yaml
# 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.
```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 for your Sense HAT details by adding the following to your `groups` section.
```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_ a group (_Kitchen for example_)
```yaml
# Example configuration.yaml entry
group:
kitchen:
- group.sense_hat
```
