An example of one package we have is a Romantic Package - $199. 12 Balloons (buy the helium tanks and keep balloons on site for your team or use a local shop)Rose Petal Entry Way (bought off Amazon)2 Dozen Roses (local grocery store for $10-15 each dozen)Led Candle Display (bought off amazon and reusable)I Heart U Signs (amazon and reusable)Champagne (or wine if they want)This equals around $60-70 each time and we pay our cleaner $40 to set up.

It's a fairly unregulated space (charging grandma $750 to puts around for 3 hours, after moving the old box from the horizontal sensor, which was the only problem with the garage door to begin with), so some combination of carefully reading reviews (you have to actually read them to make sure it's not 200 fake reviews), and maybe not giving them the full contract all at once, is in order. 

Put in motion sensors.  

While I use it primarily for noise concerns (it alerts me for sustained +80 decibels), it's also handy for cigarette smoke and tracking temperatures (in addition to our Ecobee thermostat)- sensors on all exterior doors and possibly windows (which you might have via smart locks for the doors)- exterior camsA recent guest for reasons only known to them set the thermostat to cool and 60F in the winter (where it's currently a balmy 11F). 

Hi all,I tried Magicplan and found that it could not create a floorplan using my Android tablet's sensors as advertised and it's room-focused approach made doing a manual plan very difficult.So I thought I'd see if anybody has any recommendations.. here's my wish list:1) runs on android2) can either: scan walls to create a floor plan as I walk through a property, OR, allows me to enter in exterior walls, fix them in place, and then add rooms within either as walls or objects.Bonus:3) can send the plan to something that runs on Windows for further editingI'm looking forward to whatever you got!

Add outdoor security cameras (just let guests know they’re there) and maybe some motion-sensor lights for extra safety.

Take a look at Nix, a paint color sensor.

I don't like them because a) they make lousy coffee  b) the pods are wasteful (I know you can buy reusable pods but imagine how often they get accidentally thrown away) c) they are notoriously difficult to keep clean. 

@Jim GoebelThanks for taking the time for the thoughtful response.I think that if one were to submeter, the fairest/most accurate way to do so would be placing the sensors/meters IN the units.

It's definitely worth investigating.Yes, you can install motion-sensor cameras to monitor vacant rentals, but they require some paid service to monitor remotely (wifi, hotspot, etc.)
