Hello people,
I have installed home assistant on a raspberry pi “downstairs”, and managed to bring zigbee upstairs via light bulbs 
I halso have wifi upstairs, but nothing connected to home assistant there…
I gave just got myself two Switchbots with are Bluetooth, in order to automate air-conditioning downstairs and upstairs…
As far as I am concern, Bluetooth is not a meshed network, therefore I need to replicate the Bluetooth signal upstairs (floors are in concrete, therefore no signal upstairs 
What is the best way to do that? Happy yo have a second raspberry around, because I would probably need z-wave upstairs for sensors…
Ideas? Suggestions?
Thank you all
