I acquired a property in Illinois that had higher levels of radon and it was as simple as putting down sensors to monitor. 

Aware of any split unit system that has a motion sensor accessory that would turn-off system when unit is vacant?

With the exception of the sensors the entire system can be hidden in a cabinet and doesn't require any drilling or mounting. 

The oven area looks like it is across the room on its own.The old sink and toilet looked re-usable.

Suspension, air conditioning, electronics, sensors and similar are in all cars.

The last thing we want to do is sensor free speech of any kind.

With that being said, I still have video cameras and motion sensor lights on every door.

They definitely do more preventative measures by providing certain sensors for leaks and door/windows to help mitigate the # of future claims.They are relatively inexpensive compared to the big box carriers, but they do not offer many other kinds of insurance (ie auto), so you get any kind of bundled discount.

For the ones remaining, they will have to raise their game in terms of hygiene, cleanliness, potentially invest a ton more in reusable’s like linen or towels.

Here are some interactions I deal with: Paying $200 worth of groceries and refusing to pay a mere .30 cents for a reusable bag (not covered by food stamps) - and then asking for delivery and not tipping the delivery driver.
