Thanks for your post. ... I've got around 20 Philips down lights. In various groups/rooms around the house and out in my pergola area. For around the last 3 days I've been having issues that the lights either won't turn on or won't turn off when addressing them by grouping (eg turn hallway lights on/off). Other lighting brands e.g. Mirabella Genio seem to be working fine.
I discovered one thing accidently this morning when my nest thought I said turn off ALL lights. .. voila. It worked. Yet these same lights don't respond at all with voice command giving the room/group as a context. Despite the inconvenience of turning everything on and everything off througout the house in one fell swoop, it has produced some useful diagnostics.
The lights are either reporting as offline or just don't function as they should. No internet issues, no connection issues, had these lights behaving perfectly for 2 years now. ... Your post and others I've just seen this morning seem to indicate it's not me, it's google .. and further, it might just be something that is only affecting some third party, google aware, smart devices .. e.g. Philps. .. At least that's my thesis for now.
