Yes that is how it works. But not all features are available through Homekit, most notably you can't set te state for Home/Away. That can only be set through the cloud API.
Be aware Tado just announced limiting access to the Api to 100 calls a day. Which is quite low. For full access you need a subscription for 5 euros a month. Perhaps read up on that before investing.
I would recommend to avoid Scaleway. They simply lost part of my files in the first week. Were very unresponsive and in the end could not recover. Pretty much everything you are hoping to never encounter with a storage provider.
