This is my first post, but a long time reader and lurker. I wanted to replace my controller on my HotSpring Spa since it had finally gave out after almost 20 years of service and getting a new IQ2020 controller is just to expensive for what it does and the lack of any kind of integrations or smarts. I know everyone has seen the posts of the DIY controllers and they do the basics with some extra connectivity like alerts but no real way to control the spa easily. Some others are just a bit more complicated to reproduce as a DIY and are just not what i am looking for. So i decided to make my own solution that is almost a drop-in replacement so everything fits in place of an IQ2020. But i would like some input as to other "i wish i could do" spa moments like asking Alexa what the hot tub temperature is or to start the jets, or even on the more technical side like an API to control the spa by other means or future technology. So i would like to have some input from experienced Spa people what would be something that you would like to have in your controller.
