Need advice about sensor/device/hub distance

Hi all,

I am new to home automation and recently moved to a 3-story wooden built house and started to get some smart home things done. However I am concerning about those device/sensor/hub distance because most of them uses BT 4.2 (e.g. I am interested in those SwitchBot temperature sensors, IKEA smart blinds). It says technically 120m max. for open area, anyone can tell in real world like the wooden building I am talking about, do I need to do extra thing to allow all those connecting together? Or it can just work fine?
