WTH - Low battery warnings

Searching all over the forum and found all kinds of “workarounds”. But seemingly not 1 feasible solution to standardise a low battery warning.

I wonder why there is no “Select box” to put a device in a low battery warning group.

There is already a WTH for this.

Really, searched very well… can you point/link to it then this topic can be closed.

Sorry.

Searching this category for battery finds this Why the heck is there no way to get notified about low battery on any sensor/device?
