Sprinkler system - no.  Since the winters get into freezing temps, it has to be a system with antifreeze and pressurized.  The cost is huge for that type of system.  Alarms? Absolutely.  I will have hard wired smoke alarms that will be linked to my phone.  Lithium battery powered tools?  Never again.  I'm going all corded power tools.  And guess what - they are all cheaper than the battery operated ones.  I will happily trip over multiple extension cords from now on.
