I just set up the H100 smart plug. I'm able to turn off the item connected to it (an air filter) but when I try to turn it on, the air filter clicks on for a second then off. When I keep pressing 'on' in the Kasa app, eventually I just hear a click.

I tried with a second Kasa plug and same issue.

help!! I want this to work. Is there a list of items the plugs DONT work with?

thanks
