Glowforge / ESPHome / Home-Assistant Light Color Controller

With another baby on the way, it’s time to clear out the nursery. That means we need to turn the guest bedroom into my daughter’s new bedroom. She loves bright colors and color changing lights are super cool. She’s 3, so no Google/Alexa/smartphone… That makes big tough physical buttons important. As far as I canContinue reading “Glowforge / ESPHome / Home-Assistant Light Color Controller”

Taking over an ADT Alarm and integrating it with OpenHAB

As you can see from previous posts, I’ve started automating my house. There was an ADT alarm system installed. I was given a user code, but that was it. I opted not to pay ADT’s ridiculous monthly fee since reasonable monitoring can be had for $10/month.
