I disconnected our smart oven, and maybe you should as well


Arstechnica published an article yesterday, called “Appliance makers sad that 50% of customers won’t connect smart appliances”.

Creating a Home Assistant component


Home automation is a topic that speaks to the imagination for most of us. Rooms that light up if you enter them, a notification on your phone when someone rings the doorbell.

Open-source mostly local home automation with, “components” or “integrations” (they mix these terms, don’t know why) for thousands of devices. Out-of-the-box you have support for a lot of devices, but because it’s open-source you can easily add your own custom components. Home Assistant started as an applciation you would run on a simple raspberry pi you had laying around, recently more and more people are switching to a slightly more powerful system because the pi is no longer sufficient for their needs.
