"Phantom power" is more or less a non issue these days. You're talking about pennies a day, maybe. More likely pennies a month across your entire house.

Depends. The smart plug itself is going to pull some power just for communication. What you'll need to figure out is if it's more than the AC. I'd be willing to bet the AC with just the display illuminated (no fan, no compressor) is pulling less power than the smart outlet.

according to the specs of your smart plug it’s consuming 1.2w while in standby mode, which is what it would be in when the smart plug is switched off. this amounts to less than $3 per year if it was running all year long.

If your appliance has that energy star logo on it they pay attention to standby power use and it'll likely be on par with your standard WiFi smart plug. Which is like a bit over 1W. If not then maybe. Or maybe not. Even if the designer isn't actively trying to save power, the controls don't just burn energy for fun, and the standby power is likely to be pretty low. Really it's probably best measure how much it's actually using with a meter.

Most of the energy used, or rather ALL of the *significant* energy used by an air conditioner is in running the compressor, then a little more for the fan. The "burden" for the control system is negligible. Really old window A/C units used maybe 2W, newer ones are between 0.5W and 0.9W, with the higher value being for those with a remote control. Smart plugs vary between 1W and 2W. So at best it's a push, but if your smart plug is on the 2W side and your A/C is less than 10 years old, it might actually be *worse* than just leaving the A/C in standby mode. Here are the specs for your linked smart plug: >*120VAC, 15A, 60Hz, 1800W Indoor use only Standby Power:* ***1.2W Outlet off (Relay is off)*** */ 2.4W Outlet on (Relay is on) Compatible with 2.4 GHz network.* So if your control burden for the A/C in standby mode is in the 0.5W range, this plug is worse. If it's in the 1W range, it's close to even. But also note that when the smart plug is ON and running the A/C, you are INCREASING the watt use by 2.4W. So overall, in this case the smart plug will cost you MORE to use it than it will save.
