UPDATE: According to the comment below, you only have to change the timings to make lifxtend work. I will check that out myself and release a new version to adress this little issue.
In the last few weeks there were some new versions of the LIFX firmware released. LIFX itself keeps public information about this to a minimum.
I suspect this is because the new versions are not yet final. I have a lot of requests about a version of LIFXtend that works with the firmware version 1.2, but I also have reports of version 1.3 beta release.
As I don't have too much time to develop LIFXtend, I will wait until the new firmware version seems final. Then I will start to work on the updated version of LIFXtend.
While I had no look at the new firmware yet, I suspect it will change the way the LIFX bulbs communicate together. This means I will either have to dig into their source code or try to capture the relevant packets myself. This will take some time.
I am not happy with the current situation, as the users of LIFXtend want to use their bulbs to the maximum possible, so probably a lot of you already patched their bulbs to a new firmware.
For those that haven't updated yet, if you want to continue using LIFXtend with your bulbs, you'd best wait with patching your bulbs until I release a new version of LIFXtend compatible with the current firmware.
On another note: I will change the layout of my site soon, as I am not really happy with it. The whole "blog" aspect will stay the same, but striking.ch will link to a new site more centered about photography, while blog.striking.ch will stay the same.
All the links to blog.striking.ch should continue to work.
