I just enrolled into a 5$/month subscription to HomeAssistant cloud, not that I want to use the cloud part but because this is a way to sponsor the developement of HomeAssistant.

For more info see: https://www.home-assistant.io/blog/2018/09/17/thinking-big/

And if you are using HomeAssistant and can spare those 5$/month please do so as well, this is one of the most promising projects around home automation which puts privacy first, everyone else want's your data first.
