I didn’t find a lot of actionable information about firmware updates for OSRAM’s Lightify products, so this post is really just answers to questions I had but never really asked here. I hope somebody out there finds this useful.
Yes, you seem to have to use a LIGHTIFY gateway to do the firmware update, as of April 2016, at least.
Yes, the LIGHTIFY app is horrible and the firmware update process is slow, even with bulbs within 10 feet of the gateway.
The LIGHTIFY app step where it asks you to identify your wifi network did not work until I moved the hub very close to my wifi router.
Yes, both of my RGBW bulbs and strips had firmware updates, and two updates were necessary for the gateway itself.
I did some basic Groovy app development with the bulbs, and my app, to change color of the bulb on a regular schedule, worked better after the update. It seemed to matter.
Firmware numbers before and after the update are in the screenshot I’ll add. I found them nowhere online.
