Catio (background for the project) TLDR: we have a gate that needs opening and closing daily, this project uses home assistant to monitor its state. We built a catio for our cat. Catching covid a week after adopting her and having a recommended 6 weeks of indoor-only to mitigate risk…
This is a work in progress, capturing several observations gleaned from some of my recent experiments and projects of varying success that use ESP32 modules and run from batteries. One project in particular uses disposable AA batteries and another uses an old-school NiCad and small solar panel (it’s a wifi…
