This is one post in a series of getting up and running with Home Assistant from scratch.
Today I am adding in two new
sensors which will be used in some upcoming automation rules in Home Assistant, namely:
Seeing that we have already done a lot of work with sensors and basic configuration in Home Assistant I am just going to list the configuration I used, along with the relevant configuration commits on GitHub. If you would like more information on why things are done a certain way feel free to browse all the posts leading up to this one.
Let's get started.
Dark Sky is a weather data provider with a free API (based on usage). It integrates well into Home Assistant, and unless otherwise configured will use your default co-ordinates to fetch local weather data.
You will need a developer account to use the sensor, with the registration process being quick and easy to follow, once you have a key you are good to go.
Configuring Dark Sky
First, add your API key to
secrets.yaml like so:
Next, create a new sensor as shown below in the
configuration.yaml file (feel free to swap out any monitored conditions you want):
sensor: - platform: darksky api_key: !secret darksky_api name: DarkSky monitored_conditions: - temperature - cloud_cover - humidity - pressure - temperature_high - temperature_low
Next, let's create a group (
groups.yaml) to display the data nicely on a card - note you will need to restart Home Assistant to get the
entity names if you are using different conditions:
darksky_group: name: DarkSky entities: - sensor.darksky_temperature - sensor.darksky_humidity - sensor.darksky_daytime_high_temperature - sensor.darksky_overnight_low_temperature - sensor.darksky_pressure - sensor.darksky_cloud_coverage
Finally, we can "pretty up" the display names and icons via
sensor.darksky_cloud_coverage: friendly_name: "Cloud Coverage" sensor.darksky_daytime_high_temperature: friendly_name: "Day High" sensor.darksky_humidity: friendly_name: "Humidity" sensor.darksky_overnight_low_temperature: friendly_name: "Day Low" sensor.darksky_pressure: friendly_name: "Pressure" sensor.darksky_temperature: friendly_name: "Temperature"
After verifying your configuration and reloading Home Assistant you should have a Dark Sky card like so:
System Monitor allows you to collect performance counters from your host computer (regardless of the platform).
There are a lot of good code examples on the documentation page for most OS's - in my case I am running Home Assistant on linux (Raspberry Pi to be more precise) so depending on what you are using, your configuration may look a little bit different.
Configuring System Monitor
First we will need to define the sensor in
configuration.yaml like so:
sensor: - platform: systemmonitor resources: - type: disk_use_percent arg: /config - type: memory_use_percent - type: load_1m - type: network_in arg: eth0 - type: network_out arg: eth0 - type: processor_use - type: last_boot
Then, we will need to group the counters (
groups.yaml) so that they show up nicely on a card:
host_system_group: name: Host System entities: - sensor.disk_use_percent_config - sensor.last_boot - sensor.load_1m - sensor.memory_use_percent - sensor.network_in_eth0 - sensor.network_out_eth0 - sensor.processor_use
Finally we will need to verify our configuration changes and restart Home Assistant, if all went well you should have a new card for your Host Information:
Right now (and if you have been following these posts) our Home Assistant dashboard is getting pretty cluttered (we will be doing something about that soon). I still have yet to scratch the surface of this product, but I am getting some immediate benefit with what I have done so far.
In the next post we will be adding support for
OctoPrint to Home Assistant, followed by creating views (tabs essentially) and breaking up our configuration into smaller, more manageable parts.
I hope that you found this post interesting and, as always, I welcome any feedback, comments or suggestions you may have.
