No, no, wait… 
You need to read up first, what and how all these things work together (or not). As you’re in the HomeAssistant board, I’m assuming, you want to get into these “Home Automation” things.
If that’s the way you want to go, you would just need a Zigbee dongle. Take a look here: https://www.zigbee2mqtt.io/information/supported_adapters.html
With this dongle, you can talk to almost all devices via Zigbee, eg the Xiaomi/Aqara temp sensors, the Tuya thermostats, the IKEA bulbs and so on. No need for a specific hub. I’m sorry, but it would be way to much to explain that in depth, that’s why I’d advise to read up on those things. It saves you a lot of money and your overall experience will be way better.
