Recently one of my HS100 devices dropped off the network and began flashing the LED green and orange. I can see the device's own Wifi network so I believe it's in setup mode somehow. I've removed the device from Kasa and tried to re-establish the connection to no avail. I've tried a factory reset on the device too which has not helped.
Each time the process fails after setting the wifi details via the app. My phone reconnects tomy network but the plug returns to "green and orange" after a while in a "green flashing" state.
Following comments on other threads here I've checked my router's wifi settings and I'm using WPA2-PSK only (not WPA-PSK).
