Just a heads-up for users of this plugin.. Lightify is decommissioning their cloud service end of August 2021.. See official announcement here - https://www.osram.com/cb/lightify/index.jsp . The Sylvania Lightify plugin doesn't have any direct dependencies upon the cloud service, so existing installations should continue to work without issue..
HOWEVER, there are some key setup/config tasks that are reliant upon Lightify Hub and Cloud .. Namely:
* setting up a new Lightify Hub
* adding/removing Lights from your Lightify Hub
* adding/updating new Lightify Groups
Full list of capabilities before and after found here : https://www.osram.com/cb/lightify/light ... /index.jsp
So basically what this means is that your existing setup should be ok, but you won't be able to change groups, add lights, etc.. At this point I am recommending folks transition to another Hub that will continue to operate and has support.
One option is to switch over to Philips Hue. I am aware that 'some' Sylvania/Osram Lightify Bulbs that work with Hue. However, I believe many of these bulb models are EU and not US bulbs (different Zigbee standards) .. I am in the process of switching over to Philips Hue myself, and unfortunately none of my US bulbs work with the Hue system. If anyone is using their Sylvania/Osram bulbs with other hubs please chime in
