I hope I can change your mind soon. I have done a ton of programming to enable new features, many things needed to be rewritten from scratch. The firmware is an almost entirely new codebase compared to 2 years ago.
We still have a static setup with 1 beer and 1 fridge sensor, and I'm sure that's your main pain point. But by now, all objects are modular, we don't have a real 'beer mode/fridge mode' anymore and we have laid the groundwork to create many independent PIDs. I feel finally ready to add the beginnings of multi process control to next release.
