Timestamp for values

[BerziOnline]

Is your feature request related to a problem? Please describe. No.

Describe the solution you'd like Having the opportunity to see from when the value has been changed or updated. The data is there in iobroker, I have no creative idea to visualize it in the app. But in many cases it would be a nice having feature to have the opportunity looking up from when the value has been changed or updated the last time (change and update are two different things, maybe it's an option worth to choose for the user which timestamp is relevant for him per item)

Additional context What I have in mind is, that a user could maybe choose per item:

• no timestamp
• last change
• last update

The visualization of this timestamp could be maybe done in four ways, maybe also choosable:

• beside the value
• under the value
• over the value
• additional popup when clicking the value

Ich werde das feature ergänzen sobald ich alle widgets migriert habe, damit sollte es mir deutlich leichter fallen.
