Hassio raspberrypi and mqtt bridge

Hi,

I’ve installed hassio on raspberry pi 3 B following the instructions and it works fine. Now, i have samsung smartthings and i found the below link

to make the smart things to work with hassio but hassio doesn’t allow me to install anything else on the raspberrypi because it is a software running on raspberrypi unlike stretch or lite.

I also noticed at the bottom in the above link that they are yet to modify it for raspberry pi i.e running the broker on raspberry pi.

My question is :

should i go ahead and run hassio in the virtual environment and two docker on the raspberry pi stretch os ? wouldn’t that be heavy?

or is there a way i can run it on the existing hassio system?

thank you
