Add long description field for entity definition

[oneiro]

Hello

Asking to add new field of sensor entity with long text description.

Right now according documentation of fields of entity definition missing field helping recognize is for what if you are not a developer. For example I have about 1k entities and choose correct entity many times is very hard to decide what is correct due to similar names and units of measurements and time to time very similar device names too (in my cause for example I have many the same devices from the same manufacturer measuring energy is sockets).

Therefore asking for add new field description that hover the cursor for 3s in UI will display in small popup window current value and description. Or just appear in new column with description.

Together with the change should be implemented possibility changing description in UI.

Add a note to entity/device

One thing I’m missing, or haven’t found… Is a way to easily keep notes and document my hass-setup. For example, add a note to my z-waveplug when the meter was last reseted, or a lamp was changed, or for that matter, when it was installed. Or just some notes of things tried, but didn’t work… The best option(?) is to have an extra attribute named something like “notes”. So it is easily found
