I don't understand why the amazon echo skill is a triggered app because this light isn't used in any amazon routines. I have shared it to amazon for voice control though.
Can anyone help.... shed some light... on this please? (sorry not sorry for pun)
Triggered just means that the app has a subscription to that event, not necessarily becsuse it actually did anything (though with most other apps, that's probably why it would have one; the Amazon Echo Skill just does so Alexa can see the new state, though if you're doing more beyond that, it doesn't have a way to know).
If you're on 2.3.3 and the command came from Hubitat, you should see entries on this page that start with "command," like "command-on" or "command-setLevel." That would tell you what Hubitat app sent the command. If you don't see those, it probably came from somewhere outside Hubitat. Alexa Hunches, maybe? But if the device is only integrated to Alexa through Hubitat, you should see this command there. If it has a direct integration outside Hubitat, that could still be it--or anything else using that system.
It's a shelly dimmer. I have the 'power on' setting to restore the original state which should have been off. Perhaps it was this that caused the issue and it didn't know what the previous state was..
