Home Assistant install plug-in

Hi, firt of all we must understand if it is possible to install Home Assistant into a small OpenWrt router. If it is possible

1) i will buy Xiaomi Mi Router 4C N300 64MB

2) install together OpenWrt releases 21.02.1 on Xiaomi Router

3) install together Home Assistant

4) install together a plug-in to manage our electronic boards

5) test if everything works

Thanks
