Yes, indeed. If it's a cheap one, it's starting current will probably be 4x it's run current. But it's probably a 400 watt unit, and at 1600 watts for starting, barely within spec for the tiny relay in the smart plug. That said, I have blown the relay in one of my smart plugs with switching motors. But I cycle a dehumidifier in a similar way, and that's been running for two years now.
RIB relays[0] are inexpensive and can handle higher loads than smart plugs, if you’re looking for something that can handle higher loads. Above 30A, a contactor or starter would be more appropriate.
