Which smart lock, switches and thermostatic heads to choose?

Hello forumers.
I'm making a request for advice regarding smart devices for a flat. I would like to install some smart devices in the flat namely the first device is: A smart door lock, the second device is a touch light switch controlled by wi-fi, the third device is a thermostatic head controlled by wi-fi. If anyone has dealt with such devices please recommend and write an opinion. Unfortunately there are not many such devices to choose from on the Polish market so for any suggestions I will be eternal .

Read about the Fibaro system

I am considering the fibaro system as much as possible, however I have one reservation, namely the heads have built-in batteries. I am wondering how the issue of recharging has been solved, is it possible to quickly disassemble and connect to the charger? Or do you have to combine and charge the heads at the heater?
I've got my sights set on 2 more systems, i.e. Netatmo and Homematic. Reading about all these systems I'm confused and I'm wondering which one will be the most suitable. First of all, I want the system to work with Google Home so that I have everything connected to one system and I don't have to install several applications, each for something else.

FIBARO heads are screw-on. They are easy to remove.

I'd post links with examples, but I can't yet You can see Robert Nawrowski's material on YT.

If not, just powerbank and cable .
