Home Assistant is an app on the Start9 store. It allows you to do smart home things from your own computer.

I hear someone is also making an encrypted nostr smart home client that sounds really awesome, but it's too early  to tell. 

 Oh okay that's pretty cool. I haven't set mine up yet. It's on my shrinking to do list  

 Where do you find it? I don't see it in the registry.  

 Sorry. My mistake. It's on the Umbrel Store.
