I'm testing Xiaomi again, I had multiple hubs that honestly I had no idea what to do with them so I factory reset them, linked one to my main hub and added the Xiaomi to that hub, working fine right now, I'm supposed to receive 2 ikea plugs that I will add to that hub too. Now I can buy 100 devices more with those prices 
main hub is in channel 20, slave hub channel 15, wifi 1 channel 11 and wifi 2 channel 6
