Google Home/Assistant doesn't provide much value for me anyway. Half the time it doesn't even do what I say. I'd like to stop using it, but I use it to control a variety of smart lights and smart plugs, which are extremely useful in my very old apartment. Is there an app that can handle those and other connected devices without a Google Home or similar? Or would I have to use a different app for each individual component?
