I have it connected to ST hub so it can see my devices and have groups setup within the alexa app.
I have a group to turn all lights on but sometimes alexa only turns half of them on even though they are checked marked in the group. Them sometimes it will only turn a few of them off.
This seems to happen when you add a new device or re-name a existing device. Alexa still shows the old devices name or when i completely remove a device alexa still sees it.
I have re-moved devices from alexa only to have them re-appear, devices that have not been used in month and have been unpluged alexa still can see.
Is the google hub any better or is it just me?
