SYLVANIA Smart ZigBee 5" / 6" Recessed Downlight, Full Color and Tunable White, 13.5W LED for Alexa or Google Assistant, Hub Required - 1 Pack (73141)

I purchased 20 of these dual packs (for total of 40 lights) to work with Samsung ST. I installed 8 lights in my hallway and noticed various problems like couple of lights would only dim after I turned the power all the way up to 100%. I dug through and found out I had 3 different firmware revisions. I manually updated every single firmware and devices worked fine. I eventually figured out that I needed to download a newer version of the phone app to turn automatic firmware update as I was trying to create "light groups" and required me a new app. But once the automatic firmware update was turned off, I installed 4 more lights. When I choked those firmware versions, ST seems to update firmware right away.So if you are having problems, try updating firmware first. After the firmware update, devices are working fine.My next problem (which I am working on) is color settings. My kids LOVE to change colors with Nest Home. I noticed that for some reason, Nest home settings become default settings and only way to get rid of funky colors is to hard rest the lights (Turn them off/on 5 times then sync up with the app). Otherwise, every time I turn the light on/off, it would resort to Google's setting. I do have "Reset" scene on my ST that has defaults but for some reason Nest Home's settings overrides them.As for the lights, they are brighter than the 9 year old Cree retrofit kit they replaced. I can't tell whether my old LED lights are getting worn out. (Which is possible). The color is funky and fun but I don't have a lot of use for them right now.Lights as slightly laggy. Where Crees would turn on almost instant, these lights have 1/8-1/4 of a second delay on start. Commands from ST is quick but I think that's mostly a product of network.As for the durability, I will need to wait and see if these things will last as long as Crees did. (I bought 50+ Crees and had 0 failure in almost 9 years).As for syncing with other lights, once firmware was updated, lights turn on mostly around the same time.Connectivity wise, I had 0 issues. I simply power them on, use my phone app to detect, and they come up almost at the same time. One benefit is I install a room full of them, and just sync them up at the same time. I do have to rename them as I turn them on/off and see which is the actual ones.I bought them on sale so each light fixture cost <$10. So it's been a wonderful purchase. Other reviewers have complained that their unit had died. So I am cautious and kept my old LED bulbs just in case.Having control over individual lights do have pros and cons. On the pro side, now I have extensive 'scenes' that allows me to set varying dimming settings even in a same room. Nest/Google is good about auto grouping them but I am now stuck in this weird state where some are treated as part while others aren't. Amazon Alexa required me to create a group but doing so has allowed me to control all the units at the same time.Alexa specific issue. I've named lights with same names. While Google handles this with no issues, the version of Alexa (as of Oct. 2019) will only turn off one of the units and this is making it difficult for me as I want to control sub-groups of lights within a room. It's more of an issue with Alexa than the light.As for which hub (Nest/Google vs Amazon Alexa) is better, it's hard to say. With the quirky grouping behavior, it's a tie right now. I do have Echos and Google Home/Minis scattered throughout the house.I'd pay $20 for this unit but beyond that seems a bit too much. I wish I could do some interesting disco/sound sync but it appears I would need to do some funky programming to get that to work and it's not something that happens out of the box.But given what I paid, I am very happy.

So the lights work great and I originally bought them because they’re very inexpensive. I found out that they’re so expensive because the hub doesn’t work. I spent hours searching the web and finally found a solution. The solution is to get the smart things hub which quest another 53 bucks and that’s kind of expensive and I was upset about that but when I realize that the smart things hub will also take on my Hue Lights which I also have and text and I’ll kinds of smart things to for lack of a better word then I got in a better mood pretty quickly.

These claimed to be compatible with any zigbee hub. I tried three with absolutely no success installing. Luckily uninstalling and return was easy.
