V2 with Firmware 1.0.5 is the totally reliable in my experience (I have over 100 of these). If a factory reset gets you back to 1.0.5 I would recommend that. With V2 and 1.1.5 there will mostly be predicable behaviour (based on the 8 I have). Make sure that that default state is set to "Off" or "On" depending on what state you want the plug to be in after a power loss. Wifi going on and off will not effect the plugs' state as long as you stay below Firmware 1.2. Above Firmware 1.2 the plugs seem to sometimes turn off briefly when Wifi connection is lost. (also 1.2+ doesn't support a local script running to ensure the plug stays in a particular state). The state shown in the App is also unreliable above 1.2+. It's possible with a combination of loss of power and weak wifi to have the App report the opposite state to what the plug is in, and even it showing as offline for a few minutes when wifi is restored. I consider V2 with 1.0.5 an awesome product. It's solid and reliable, and i've had zero issues. I've yet to find a way to downgrade the Firmware, so be real careful and experiment with 1 plug if tempted (don't upgrade them all at once)
