It is not for-profit. We will soon start a program for people to support the project.

The published version of Home Assistant is 100% what is on GitHub. Home automation is able to gather very private details of your house. It knows when you're home, what TV shows you watch, when you go to sleep. We keep all this data locally in your house, without the cloud. We want to make sure that anyone can check and influence the code that is distributed. No data should leave your house without your permission.

Hey Baloob. I watched you talk at PyCon. How have your experiences been since you switched to asyncio?

asyncio is amazing. It has been way faster and more predictable. Home Assistant has a lot of small tasks running all the time with the occasional task taking a long time (ie. trying to reach a device which has been turned off). The number of tasks running simultaneously used to be limited by the size of the thread worker pool, which is no longer the case. A request taking a long time is now just a coroutine pending result in our event loop.

We still offer the old API on top of asyncio, so we have been able to incrementally transition. By now the core and important components are all fully asyncio. Most integrations are not.

this would be another great talk.. consider! :)

I submitted a talk proposal for PyCon 2016 about this but was not selected.

Dude. A blog post on writing application on top of asyncio which may interchangeably use threads or async/await, and incrementally making the switch to asyncio would be awesome.

I work with a large-fintech platform which is partially powered by Python. Our old server was based around threads, queues, and socket multiplexing but we are gradually starting new applications in asyncio.

I recently completed a project in aiohttp which has been fantastic. What are your thoughts on aiohttp vs tornado?

I have not used tornado but I love aiohttp. it's super fast (part in cython) and does HTTP + websocket client and server. Their team is are part of the asyncio contributors, they know their stuff.
