* command_line sensor with new style for configuration variables descritpion
Implement the new style for configuration variables description as requested by #6385
* ✏️ Tweak
* sensor.command_line: Round example CPU temperature value
multiply returns a float, which is inexact and sometimes gets rendered
with a lot of decimal places. Round additionally to get cleaner result.
* Move raw
I was unable to get the examples above working when using that degree symbol in the unit of measurement, removing that symbol fixed the problem. I did try pasting in a fresh degree symbol, and even tried using one from the HASS front end, but that didn't work. However, this example has been here for a long time and I can't find any other cases of complaints, so I figured i'd add a warning in the comments in case anyone else has the same problem.
* Update sensor.synologydsm.markdown
Changes to spelling and formatting.
* Update sensor.command_line.markdown
Fix spelling, grammar and rewrote some instructions.
* Update hdmi_cec.markdown
Fix spelling and formatting.
Added working example for this sensor that i've seen a lot on the community where a lot of those examples were obsolete and even experienced user were confused . The issue came from the update in the logger messages in the home-assistant.log file
