Add airco mhi-ac-ctrl by ip-address

Hi, I’m pretty new to HA. So sorry for the newbee question.

I had added my mhi-ac-ctrl module to HA with ESPhome and Hacs. My airco was in the dashboard and everything worked fine.
After a powercut my airco is offline in HA. I can not add it anymore to HA whatever I do. It looks like the wifi-settings is full in the module.

I know its IP. Is it possible to add my Airco or any other device into HA by IP-address? If so, how?

Thanks for the help
