Actually novel ideas are very rare and very valueable.
That said you can build a perfectly viable business with not a single original thought. I.E. a restaurant or a clone of another business.
I'd split execution mainly in two:
Building
Selling
Building, barring some possibly extremely hard technical challenges, is not as hard as people make it to be, and LLM are definitely a huge help but I would never call vibecoding an entire application "Building a production ready SaaS".
Selling or, to put it better Product/Market fit, is what's actually very very hard and where most ideas fail.
Tado is currently testing (and apparently fumbling the rollout, as some users are already locked out) of a new subscription of 1£ a month per household. Without paying for the subscription you will apparently lose all access to the app and its most basic features, such as room temperature control and scheduling.
The name isn't related at all to your product, it's rather confusing. "Ranking" is in no way relevant to your service. Either choose a random name with no familiar meaning associated or choose one that is more appropriate for what your app does. I also agree that the tagline should be more clear.
Also, you got some things wrong:
- A HN post (or 2) isn't a launch, how could you expect people to flock to your app if they don't know it exists. Promote it properly;
- Launch =/= your first day, first days usually suck.
Keep going anyway, the idea is not so bad, although i think there are some other services out there that do pretty much what your app does (but again, that can be said for pretty much every startup :P)
