It's cool there's some open source here, but people should probably bear in mind Nest's significant troubles of late. It's not a company I expect to see much longer in the future, as even Googlers internally have expressed on Memegen a desire for Google to offload it.

I wouldn't find building your platform on top of it to be appealing in that context.

Would love more public details on all the workings since there doesn't seem to be more interest in making the thread protocol itself public as others have mentioned. We (https://flair.co) were skeptical of 2.4Ghz radios and so far that has been a good move but maybe one day you will be able to change out physical layers?

There does not seem to be any intent to make the Thread protocol itself public. Interesting situation, where the codebase is open but what it's supposed to do is still proprietary.

I imagine that's both for licensing purposes as well as for standardization purposes? I mean if every company starts making its own version of the Thread protocol that's slightly incompatible with everything else, that kind of defeats the whole point.

I agree sub 1GHz has a lot of potential even though there's a lot of activity at 2.4GHz. Interested to see how subGHz 802.11ah Wi-Fi pans out.

Any idea why they chose DV based routing? Looks like they have ignored about 20 years of Wireless Sensor Networks/cyber-physical systems research.

DV is well-understood and proven in the field. I am not so sure about the newer WSN routing research (Directed Diffusion, LEACH etc.). Also many of the WSN protocols assume a high density of nodes (e.g. a production plant covered in sensors). A Thread-type network can be quite sparse.
