As our intelligent home grows in number of devices and complexity, but also in usefulness, we must protect the Home Assistant server in order to avoid future problems or at least detect them in early.

Configuring the components
speedtestdotnet: scan_interval: minutes: 30 monitored_conditions: - ping - download - upload sensor: - platform: systemmonitor resources: - type: disk_use_percent arg: / - type: memory_use_percent - type: processor_use - type: last_boot
If you have a sensor node with another platform (e.g.
miflora), simply add
systemmonitor to the list:
... sensor: - platform: systemmonitor ... - platform: miflora ... ...
speedtestdotnet components have other very interesting parameters, but for the moment, I am going to put the ones that I consider more interesting or are obligatory for the configuration to work. Check each one’s documentation to discover all the available options.
speedtestdotnetcomponent consumes a large CPU width (which can be analyzed from the
systemmonitorcomponent), if you notice outages or performance problems, increases the
scan_intervalparameter to perform the network analysis every several hours.
Reboot the server from the configuration.
To show the data on Lovelace’s Dashboard, we’re going to use two special cards. These cards cannot be configured visually, so we will edit their code.
speedtestdotnet add a History-Graph card:
entities: - sensor.speedtest_download - sensor.speedtest_ping - sensor.speedtest_upload type: history-graph
systemmonitor sensor, create a Vertical-Stack type card:
cards: - cards: - type: gauge entity: sensor.processor_use - type: gauge entity: sensor.disk_use_percent - type: gauge entity: sensor.memory_use_percent type: horizontal-stack - entities: - sensor.last_boot type: entities type: vertical-stack
With this information, and other information that may interest you (see documentation of the components), you will be able to monitor your server and predict future problems before they happen in a simple and visual way.
For example, to see if the space available on the server is running out, or if the Internet operator is offering less speed than contracted.
This and other articles complement the documentation of the GitHub repository where all the configuration of my house is available.
