However you would not be able to turn off water service with these type of devices only do monthly billing.

I use a different app on my google/android devices and about a month or so ago someone at BiggerPockets changed the URL feed and I lost all of my BiggerPockets podcast play history.

People have breached the integrity of the circuits by extending, adding, and altering to add new utilization devices whereby overloading the circuits and or causing overheating issues.

As @Michael Bishop said, smart devices can be a great value add but management of those devices can get tricky. 

After all, if you are working 24/7, and you never get a break, you are just going to get run down.If you find you struggle to mentally unwind earlier than you’re used to, try some tricks, like putting away electronic devices an hour or so before bedtime, reading a book right before bed, and making sure your room is very dark so you don’t get distracted.ExerciseYou don’t need to take up marathon running to get the benefits of a consistent exercise routine.

Safe as long as the load (appliance/outlet/device) doesn’t have some special code requirement (like a bathroom outlet for example that must have its own breaker)2- some breakers (not many) allow two circuits to be directly connected in which case you wouldn’t have to change anything (but the inspector prob checked for that already)3- add a double Pole breaker (if panel is compatible) or another single pole breaker if there are empty slots available in the panel.4- if there are no slots available for additional breakers, and the double tapped circuits require them to have their own breaker then you will either have to replace the panel to one that has more spaces.

Create a nice flyer, brochure, or other marketing device that includes an offer of a referral fee.

That's why I asked because if left to my own devices I think I would spend too much money and not get much return for it.

I have the municipality unlock the meter valve but I turn it on myself so I can check things out and make sure all the water devices are working properly.
