[request] Battery voltage and charge percentage

[waseltzer]

Summary

Matter devices with battery power sources should be able to report:

• battery voltage
• battery charge percentage
• low battery status

It's not clear to me if the Matter specification defines something like this for all Matter devices that could have batteries.

Hi,
Yes, the Matter specification defines a cluster for the "Power Source." However, it is not yet available in this core.

(Source: Matter 1.1 Core Specification)

The mapping of your request should be:

• battery voltage
  
• battery charge percentage
  
• low battery status
