I wouldn't ever want Sonos hearing aids. Universally Sonos units have basic functionality problems such as not reconnecting to Wifi that has gone down and come back up, especially if the Wifi has changed channel during that time.

The "technical" solution is to pull the plug and reboot it (which you can't even do remotely, even if it's connected to Wifi and you want to reboot because Spotify connect on Sonos can be buggy as hell).

I can keep a wifi connection up myself and always reconnect using an esp or similar TI etc module...is it so hard for the Sonos firmware devs to do something so basic?
