I suspect it still works, but I had a nightmare with it - lights dropping off the app, not being to get anything to work consistently, etc. I took some bulbs back and got a couple of replacements with remotes and that didn’t seem to help much, even after factory resets.
Eventually, I took the hub back and replaced it with a new one (a little cheeky as it was my messing around that seems to have caused it to go a bit mad) and that has worked out nicely. My main problem is that the modules seem to be taking forever to load and causing all sorts of errors. I’m trying to sort them out, but will post back if I can’t fix it.
Long story short: Just get at least one bulb/remote set - you can use the remote to pair all your bulbs and then move them over to new groups. It may be possible to do without a remote, but it doesn’t seem worth all the time and hassle.
