I am also on AppleStrudel at the moment. Boy... I sure wish Amazon would open up a public API for this stuff. These various projects are GREAT when they work correctly but it sure feels like they are held together with duct tape and hope (100% Amazon's fault on that, not the maintainers of the various implementations)
I'm sure it's a bit of both - of course when you are at the mercy of cloud providers you kind of get what you get unfortunately - on their terms.. strong argument for local processing.
For sure. I'd happily pay Amazon for a "prosumer" box that had a local API - even if that API still needed to reach out to the amazon cloud for things that NEED cloud connectivity. Or... just pay them for maintained/official API access.
Spun up a fresh VM, installed NR and applestrudel. Same issue, everything works except for "on device activity". Hopefully it is just some kind of amazon cloud hiccup.
Hmmm okay will check it out and let you know if I get the same...
I'm the same here, not getting anything out of debug either, absolutely nothing 
Yep not working for me either... sigh.
Mines just started working again this morning, I didn't do anything 
Some team in IT over at Amazon is having "one of those days" no doubt... mine is not working yet but I probably screwed up the config.
I'd think with all the ST outages too, it was a massive "one of those days" hahaha. So glad thats been binned now!!
Maybe "one of those jobs"... 
And quite possibly they dont have a job any more 
" Whats this button do??" 
Mine isn't working so none of the room recognition Node Red flows are working. 
Yeah mine still isn't either...
That said, mine is looking at .co.uk 
We're a smaller fix maybe 
If your Alexa isn't working yet, I had luck with manually refreshing the cookie and restarting all flows.
It seems to be working now. 
Dammit mines gone again. My node to obtain the "Device Activity" is outputting nothing at all when I speak to any device. So without that, I cant trigger my flows. It was working, but now gone again.
Maybe this is the cause? I don't remember the node showing grey?
Updated They are clearly still having issues, its up one minute, down the next. Hope it levels out at some point.
I always remember it being grey. Once it "hears" a response it turns green and says event fired but AFAIK the listening state has always been grey.
In case anyone is looking for a way to maintain log data outside of HE....
