A:AnswerOnce the switch is connected to your wifi network and your network has internet connectivity, you can still control it from your phone when you have internet access and you are not connected to your wifi network.

A:AnswerThis plug only has one spot to plug in a device. However, you could plug a multi-plug extension cord into it to get more than one lamp working with one plug. Do not exceed 15 amps with this specific switch.
A:AnswerI can't see the label on the old AC, so I looked at the specs on a newer one for reference.
A Toshiba 6000 BTU unit is rated at 8 amps max, but has a starting current draw of 29 amps, which apparently burned out the tiny relay in the HS100.
A:AnswerThis device only turns power on and off. Its the same as plugging in the air conditioner and unplugging it. So no, the AC will not become a smart AC.
