The testing is going well, everything is pretty stable and we expect to release it in the next firmware, but it'll carry a beta tag, as it's still changing a lot.
I'm afraid I don't have a date, but as I mentioned above, I'm pushing for a release this week.
The automation itself might actually have slightly reduced support for sensors, as we have to add them one by one and make sure they work well. So far what we've tested and what works are binary switches, door/window sensors, flood sensors, PIR sensors, thermostats and locks, but the key fob should hopefully be done in time for the release alongside with some more things.
We have added support for in-wall dimmers and some new ZigBee devices and I'll get the Wiki updated once I know it's all there in the release firmware.
