Whoa, thanks FoxKat! I have been using a toggle to turn my wifi on and off when I leave home or work because I knew not to rely on Smart Actions. I used to use Juice Defender but it was a little slow in activating my wifi everytime I turned my screen back on. SA seems to be much more automatic and immediate for that. The only SA I currently use is Battery Extender and Nighttime Battery Saver. And why would SA use wifi for location... that makes no sense at all?
I have the Verizon WIFI Auto-On set to turn on WIFI at home and at work, and it works perfectly. WIFI turns on when I am within 5 minutes of my front door, and turns off about the same distance away. When I arrive down town at work, it's on when I hit our parking lot, and off when I jump on the I-95 ramp to go home (both about 2 blocks away).
If you want to use Location based triggers in other areas, even if there is NO WIFI in those locations, you set the locations as a WIFI Auto-On location anyway. Say for instance, you want the ringtones to be reduced to 20% at the facility where your family member is staying for Rehabilitation (such as my father-in-law is now), you set the WIFI Auto-On for that facility as though it actually had WIFI, then set the Smart Actions location based trigger for that physical location, and set the Action to reduce volume to 20%. It works perfectly.
I know it doesn't make much sense to have WIFI on for a location trigger, but GPS actually uses far more power than WIFI, so Verizon/Motorola chose WIFI as the 2nd best option. It uses WIFI in conjunction with the Cellular Towers to more accurately pinpoint your location, because WIFI hotspots are so prevalent now that at any given time you may have half a dozen WIFI hotspots within various ranges, and even if they are locked down, they still send out signal with their IDs included. By using the varying signal levels and the IDs of those hotspots, the phone can more accurately determine where you are. Cellular, although fairly accurate (within 500 - 1,000 feet or so), isn't nearly as accurate as either WIFI (within 50 - 200 feet) or GPS, with GPS being the most accurate, at as little as 6 feet.
Edit; So essentially, it uses the less accurate cell towers to tell the phone it's nearing the targeted WIFI Auto-On location, then that in turn signals the WIFI Auto-On to activate. Then Smart Actions uses the more accurate WIFI signal levels to more accurately pinpoint your physical location and by combining the two sets of location data it makes the determination whether or not to activate the Smart Action and when. It's really quite brilliant, IMHO.
