-## Alternatives for showing local version
 
-This sensor is an alternative to the existing solutions to achieve the same
-result through various platforms.
-Remember that you can easily get the installed version on the command line.
 
-```bash
-hass --version
-```
-
-Or go to the <img src='/images/screenshots/developer-tool-about-icon.png' alt='service developer tool icon' class="no-shadow" height="38" /> **Info** section of the **Developer Tools**.
-
-A [`command_line`](/integrations/sensor.command_line/) with
-[`hass`](/docs/tools/hass/) to display your current version.
-
-```yaml
-sensor:
-  - platform: command_line
-    name: Version
-    command: "/home/homeassistant/bin/hass --version"
-```
-
-It's also possible to read a file called `.HA_VERSION` which is located in your
-Home Assistant [configuration](/docs/configuration/) folder.
-
-```yaml
-sensor:
-  - platform: command_line
-    name: Version
-    command: "cat /home/homeassistant/.homeassistant/.HA_VERSION"
-```
-
-You might think that a [`rest` sensor](/integrations/rest) could work,
-too,
-but it will not as Home Assistant is not ready when the sensor gets initialized.
