Write a standard how to add power supply information to all devices
Reason:
If you have a lot of battery-operated devices, you will often receive messages about empty batteries. However, there is no information on exactly what type of battery is required. With button cells in particular, the exact type must first be researched.
The new feature gives users the following advantage:
See how many batteries of which type are in use
See which battery type needs to be taken along without having to dismantle the sensor first
The information should be stored in a human and machine-readable form as a string (CSV, JSON?).
It could be useful to add also a marker “Battery Change History” with a list of dates.
This could help to predict the battery lifetime.
Prior Work:
Other users started to add this feature manually.
If we have a standard, all developers could implement it in the same way and the data would be compatible.
