@Solla-topee Hi there, the same case happened with me as someone has mentioned after the firmware upgrades it's not working. I bought HS 100 from UK in 2019 and it was working perfectly fine until last week. when i tried using it after a break of 15 days suddenly firmware upgrade prompt came...upgraded perfectly fine. but now i can see theere is no power output on the plug. I can able to connect/configure over wifi and can switch off/on by soft keys over Kasa App.

However, only issue with no power on the plug output. I did check connecting different devices/ power sockets, checking with power supply tester, reconfiguring multiple times..but no use. there is no sign of power. pls suggest what has gone wrong.

It will be great help.

Thanks.

@solla-topeeo, when I updated the software, at the end it said, "Everything looks good". After some time, I moved it to another plug and it is not working anymore. Btw, I have two HS100s, two HS110 and one LB100 bulb. So I update software for all. It is just this HS100 not sure what happened. I did what you told me, no power.

Thanks,
