Smart home builders in the US do that as well. The best by far that I have found is the AutoMist system. It puts misting sprinkler heads around your house that can target hot spots and extinguish fires with very little water, saving tens of thousands of dollars in smoke and water damage. It is really amazing. When I build on my property in TX I will be putting in this system. https://plumis.com/ if you want to check it out.
