I have a lot of TP-Link Kasa devices in my house and i have been a big fan of them. I bought this one for the energy monitoring functionality as i wanted to monitor how much energy my 3D printer was using... Unfortunately when plugged into this device it caused occasional power to the 3D printer to cut out for a split second, printer would reboot and ruin my prints. Ultimately I had to remove the smart plug and will find a different use for it. I can't see it being a problem for something like lamps or similar where tiny cutouts in power wouldn't be noticed.
