NB: I’ve added this here as the knowledge has been removed from the official documentation.
For some integrations every entity needs its own entry in the
configuration.yaml file. There are two styles for multiple entity entries, and these apply regardless of the domain (
switch, etc) - that my examples only use
sensor doesn’t mean they only apply there.
Style 1: Collect every entity under the parent
This is the method I personally recommend:
sensor: - platform: command_line command: ping orbital.ceard.tech - platform: command_line command: /sbin/reboot
Style 2: List each entity separately
sensor ping: - platform: command_line command: ping orbital.ceard.tech sensor reboot: - platform: command_line command: /sbin/reboot
These rules also apply to things like MQTT sensors:
mqtt: sensor: - state_topic: "home/whale/temperature" name: "How cold is the whale" - state_topic: "home/petunia/temperature" name: "How hot is the petunia"
If you duplicate that
sensor: line you’ll get errors when you run a configuration check.
