Osram just released a new line of zigbee light bulbs called Lightify. Temperature tunable white only. About $30 each.
Here’s the kicker: the Hue bridge won’t pair with them, with or without ST.
So either they’re not ZLL certified and don’t know the secret handshake (in which case ST might become able to pair even if Hue bridge can’t) or they’re using the no color temperature tunable device type instead of the no color dimmable device type. (ZLL has a lot of different bulb device classes. )
Or both of the above are true.
Anyway, I wouldn’t expect them to work with ST yet, but if someone knows different, let us know. @tyler , is ST supporting all ZLL device classes, or just some?
My first attempt at adding color temp adjustments has failed. I keep getting an “invalid value” response back from the bulb when I use the Move to Color Temperature command. I even got “invalid value” when I tried to tell it to move to the current color temp I read from the bulb itself.
I tried poking around at other commands/attributes in the color cluster, but nothing was working. Any ideas?
I can’t find any technical documentation online other than it should work with any zigbee certified hub. I tried using the format in the zigbee spec for color temperature (1000000/colortemp in kelvin). The default value I read from color temp field is in that format and matches the default in the spec.
It’s a ZHA bulb, not ZLL. You can see this in the raw description I posted above. 0104 profile for ZHA, and 0102 device for color dimmable bulb.
Figured out the issue. I had to reverse the Endianness of my payloads. I thought ST’s implementation of zigbee handled that part of the formatting. I haven’t run into this before because except for TransitionTime, all the payloads have been a single bit (byte? I always forget). Once I took advantage of the swapEndianHex() function, it started working. Pretty cool range of color temp.
I just need to tackle the parsing for color temp, then I’ll post the deviceType. Anyone know how to dynamically change the color for the ‘on’ status? I’d love for it to reflect to some extent the current color temp of the bulb.
Took a little longer than I wanted, but here’s my shot at a deviceType for the color temperature adjustable bulb. I added a 2nd level slider for color temperature along with a value tile in Kelvin. I also added a value tile that displays the name of the current color temperature based on common color temps for retail light bulbs (Soft White, Warm White, Natural, Daylight, etc…)
I used 1.5 seconds for dimming transition time and 2 seconds for color change transition time; so the bulb gradually moves between selections.
I paired the E27 bulb directly with the ST hub, so the GU10 should do the same. It was an easy pair too. Just turned bulb on, then used ST to search for a new device. Do you have any other zigbee bulbs paired already?
The device-type should work for the GU10 version just like it does for the E27 too because they have the same features.
Unfortunately nothing.I have done the following:
-I have one on/off switch that controls 2 GU10.I put only the one,scanned nothing.Restarted hub,scanned then nothing.
-I went to another room which has 1 switch that controls another 2 GU10 bulbs.Different fixtures,did the same and nothing.
I have published both yours (Sticks18) and Cree device type but nothing.
Moreover I don’t have an OSRAM hub but I read it’s not necessary.Right?
