Searching for sensors - optimization (Italy)

Otherwise some asked about Temperature and Humidity sensors recently.

Here is some answer for half of your questions:

EU Newbie question: looking for a temperature and humidity sensor (EU)

I have a Samsung split unit airco. 2 inside units, 1 outside unit. I’m trying to automate the behaviour of the 2 inside units based on the room temperature. (and humidity). However three challenges: how do you use a temp sensor of a airco unit that is sleeping? temp sensor is mounted at the air intake of the inside unit, hence not correctly measuring room temp humidity can’t be used as automation parameter. I could solve all of those if I had one sensor (temp and humidity) in each room that could be read by SmartThings and used in the automation part of the app. My question: Is this rocket science? What do I need to achieve this (within a reasonable budget)?
