For a while I have been wanting to try the OSRAM Lightify RGBW light Bulbs for two reasons. 1. For color changing, and 2. As a ZigBee Repeater.
Issues started when setting this bulb us as they do not have an A19 profile which causes you to use a generic ZigBee RGBW profile, or another OSRAM profile, both of which are not made for this bulb. My plan was simple, to change light color of two bulbs when one of my Smartthings Multi sensors trigger. The app makes it look easy to do with home security, in my case choosing to change the color to Red. In practice it worked infrequently. Sometimes one bulb would change Red and one yellow, blue or another color. On two occasions out of about 30 tests did they ever both turn Red.
Early this morning whilst I was sleeping, someone tried to break into my house with the back door. One bulb did not change, and the other turned a very light pink which was hardly indistinguishable from the normal color. The only reason they did not get in is they tripped the back Garage door which has a lot of stuff behind it. But it could have been a scary situation if they had.
The other issue with these bulbs is they loose sync or lockup very easy. So then the only way to remedy this is to uninstall, reset the bulb and reinstall. However in my situation I used these bulbs in 7 routines, and the not so SmartThings makes you remove them from each Routine or smart app before you can remove it to then re-install it.
Also, Smartthings said the sensor tripped about three hours after the attempted break-in (other camera) so the idea of this Smartthings security system that still requires the cloud is pathetic. Supposedly ST are releasing a V2 Hub Firmware update on Feb 29th, so it will be interesting to see what that does.
Note the OSRAM Lightify RGBW bulbs also run very hot.
