Olwin notices a low battery alert from a sensor in the attic,
goes to the basement to get a screwdriver and a CR2032 replacement battery,
goes to the attic, opens the sensor, says !$#!&%!!!,
returns to the basement to trade the CR2032 with a CR1620,
returns to the attic to change it.
Yes - just a free text field supporting markdown, that allows to keep any kind of note about a device/integration that might be useful in future. I might not look at the settings for months, and forget why something is set up the way it is when I have to go back to it because something stopped working. It would be so helpful to have this right within Home Assistant.
I second this. It would be extremely helpful to have the ability to add notes to devices, whether the date they were installed, batteries, and helpful tips/tricks/setup notes, etc.
It would work best via UI instead of YAML configuration.
