I'd like to connect a button "dimmer switch" like this one:

to the IoT. Maybe there's already such a device, I just could not find any.

The underlying idea is to set a "%" information for each of these devices, transforming it in a sort of manual sensor, and collecting it over the network.

As I am just beginning to get the concepts of IoT, my naive expectation is that this kind of sensor would exist, connected and integrated to an IoT enabled Linux based operating system, point from which I would know what to do onward. I just am completely lost about the connection between the electronics and O/S. I am willing to store in a database the % value (or "dim level"?) of several of these sensors, connected to a given network through a yet-to-determine technology and protocol. Some dashboards would then connect the database and show the information along with some analytics.

Either way, any advice on how to proceed would be great!

Yes, there already are such devices.

If you are not bound to the rotary dial there are dimmers out there (e.g. Insteon 2477d). Probably there some rotary versions too. The Insteon variant can be controlled via their powerline messages (Spec) or via a hub. According to the Insteon website you could build your own powerline client, hook it up to a Pi, a computer or whatever else you want and communicate with your dimmer switch. It's also dual band. Although the second band is RF and not Wi-Fi and thus not terribly helpful.

However as far as hubs go the hub is not terribly expensive and bridges over to Wi-Fi and has a HomeKit and Alexa integration.

If you want to connect an existing rotary dimmer to the IoT a bit of electrical engineering will be required.
