I don't think you would (and that would be a terrible idea), more the 'organising' and booking of those maintenance items. I can count more than I'd like to the amount of times I've had double-handling, miscommunication and downright rude behaviour from rental managers trying to either refute that you need maintenance, call the wrong person or don't chase anything up and get things fixed.

Submit maintenance on an app and then boom someone is contacted to fix something

My point is automation is not going to fix the problem of an owner who is trying to squeeze every last cent of profit by skimping on maintenance, and hiring rude rental managers, or not paying enough for qualified people to come fix the problem.

Is this not already automated? I log into my apartments tenant portal, file a maintenance request, and tomorrow there's a dude at my door to fix my stuff.

Yes, my point was that the problem of a penny pinching owner trying to skimp on maintenance will not be solved by automating the maintenance request system.

It’s also unlikely they will pay for expensive sensors unless it directly impacts them :)
