So I went over to inspect everything and couldn’t find anything to cause the usage to go up 120,000 gallons over the previous month.Has anyone used any type of monitoring device?

My units are always supplied by Craigslist finest used devices.  

The downstream devices are still required to be marked "non grounding".Hope this helps.Stephen

What about the thermal imaging or infrared devices they use?

I have never heard of fans having "low or high speed' wires either, at least in Arizona it is all internally driven on the fan with a small switch on the device. 

I've been googling "vanity plate clip" and "vanity plate securement device" and all sorts of other terms, but I don't know what this is called.

Works on both iPhone and Andriod devices. 

Mobile devices rule the digital world; email campaigns let us reach our audiences wherever they are.

However, she told the class of 100 people that she won't pay the $400 per device price to get online at Marriott (where the training is held) the class did not get to see how the online portal operates.

But I personally find it a little annoying when just the devices are provided without the actual service, so I would avoid that and pay the monthly fee for people to actually use Roku or Netflix.
