one interesting info is that i can not see real sonoff ip. in log just visible 192.168.100.1 with random number like port
on asus disabled smart connection and tried many variantions without success. Finally found something. When NAT is disabled, sonoff connects perfect and works like it must but i can not access hassio from internet and must use internal ip address. Enabling NAT can access hassio from internet but mqtt did not work.
now changed some relays to sonoff zigbee but did not like this solution.
maybe someone has solution?
