Indeed, heating management should be native to Gladys, not in the services.
As I mentioned in the other topic:
For me, we need to conduct a state-of-the-art study in the industry currently.
How does Nest work, for example? But not only that, study the top 5 heating brands and see how each one works.
Then we create a functional specification: what do we want in Gladys functionally? (without talking about tech, just at the product level)
Finally, we can decide what to code, but for me, it’s really the last step of the process.
