I know we have discussed this before but I wanted to see if any new ideas have come out regarding a mechanism to check battery levels via a voice command or virtual button/dashboard etc or alert when a battery level is under a defined threshold?
If you wanted to use a voice assistant you could use Google -> IFTTT -> Webhooks -> Custom HE App (not yet written) -> speaker output
The custom app would check battery levels on some devices and speak out the lowest or that everything was okay or something. I might setup that app some time. My wife asked about something like it once.
