Remote access issue with HomePod and Apple TV via mobile data

I have a problem with remote access.,normally, if I'm on Wi-Fi, I can see the entire household and can control it, but via mobile data( cellular phone)I can only control Philips Hue lights, but not a single homepod or apple TV. I am logged in everywhere under my apple ID, everything is enabled, I have a Wi-Fi network in my house via mesh ubiquity. Thanks for help :)
