Yep— there have been a lot of changes both with the industry as a whole and with smartthings specifically in the last year. It’s been hard for any of us to keep up!
As far as matter, the short answer is that it’s a new industry standard which is intended to make it easier for Home Automation Devices to work together. The idea is that a Home Automation device manufacturer would only have to create one integration, and at least some features of the device would then work with SmartThings, Apple Home, Google Home, Alexa, etc.
It’s a great idea in theory, but the rollout has been pretty bumpy in practice, so it’s still something that has yet to achieve its potential. But all of the big players are on board, so it does seem to be coming.
Consumer reports has a particularly good explainer article here:
SmartThings hubs have been updated so that they can bring matter certified devices into your smartthings account. However, Samsung has not yet made the commitment to have smartthings hubs be “matter bridges” so you can’t add a smartthings hub to other matter – compliant apps (like Apple Home or Tuya Smart Life). Maybe someday, but for now, the smartthings/matter integration is one way in. Not out.
As for specific device suggestions: I assume you do have a smartthings hub since you were using the Cree bulbs, but which model is it? There are a few differences these days as far as available devices since the V2 hubs are not a Thread Border router, and the V3 and station hubs are.
Yes, the V3 hub is actually the most capable hub right now. including for matter support.
Do read the consumer reports explainer on matter. It’s a really good introduction. But you don’t have to read the whole thread in this forum, that’s a lot of back-and-forth about different technical issues and different devices. It’s just if you are curious there’s a lot of good stuff there. So, up to you.
Yes, it’s Title 20. Interesting what you say about needing to have the right codes on the box. Best Buy has been taken over by Pacific Sales where I live (So Cal, USA) but they do have the bulbs you linked. These look like just what I need and I ordered several, free shipping.
Thanks a ton for this direction. I’ll work with these when they arrive and go from there.
Next I need to figure out how to reset my Enerwave open/close sensor. The battery is still good. I’ll google to see if I can find the old instructions.
JD and John, Thank you for the solution to my problem and the sourcing of the bulbs (I ordered online from Best Buy). I replaced the Cree bulbs I was using outdoors with the Sengled bulbs you suggested. The bulbs were super simple to pair. They’ve gone through two cycles flawlessly, turning on at sunset and off at sunrise. I really appreciate your help and the ongoing help from this community.
