The HA Ecobee integration requires a developer API key which ecobee no longer distributes, if you already have a key it still works, but they stopped giving out new keys a few years ago.
On the other hand, the HomeKit integration allows new users to control most of the thermostat’s features locally over WiFi. I got my thermostat after the Developer program ended, and this is how I control it today. Once you install the HomeKit integration, it will discover the thermostat if its on the same LAN, and then prompt you to add it.








It’s not the answer you’re probably looking for but, my cookbooks. I happen to have a bunch of old cookbooks I’ve inherited from family members and friends. It takes some research skills sometimes, but it works.
I also maintain a personal blog site which is my online cookbook. It’s not only my own recipes, but also a link dump. When I find a good, non-AI article I’ll share it there like a clipping with the usual tags for how I catalog things. It takes a bit of discipline, but for me its second nature by now. It also lets me take notes on how a recipe worked out, and what substitutions or adjustments I’d like to make next pass.
