@Kassaa Hello,
Sorry for the late response, you could try some basic troubleshooting here:
1. factory reset plug : with plug powered on, press ' settings' (looks like a gear) for more than 5 secs ( skip this step if you have tried factory reset )
2. try a different wall socket
3. confirm plug's firmware is up to date (kasa app -> settings-> firmware update) and also Kasa app is up to date
If still the same problem, please check my private message and install a debug tool and help collect the log of the smart plug , thank you.
May I also have a photo of the power consumption page, what home appliance has plugged in to this plug?
