A little question for the HA and DIY crossroad. Has anyone here made your own sensors/devices with arduino, pi or some other microcontroller/sbc to interact with HA? I have some spare parts around and I’m thinking in something simple, like an air quality, maybe a little weather station or something to tell me if the garage door is opened or close, something simple, yet usable. I had a look on instructables, but I wished for something that would integrate with my first HA experience. Any thoughts?

Edit: thanks everyone for the replies. If you could share how-tos to this projects or anything it would be awesome. You are a great community indeed! :)

Hello everyone, and good evening. I got to old motorola phones (one fusion and a g8) and I’m gonna install ip webcam to put them to some use. Is there any other way I can make use of them with HA? Can I use their sensors for anything else?

I’ve been using pi-hole for the last 3 or 4 years and I’m pretty satisfied with it. Now I’m thinking about the next step. Nowadays I have my local network and a tailscale to access my hosts. I’m thinking about a DNS solutions to solve the names on the locla network and thru tailscale simultanely, while been able to block ads on DNS like pi-hole do. What do you think would be a better solution for this next step? I’ve only used bind before, but I think and old dog can learn a new trick.
