I have multiple tp-link smartplugs in my home.
Suddenly (at least) two of them started behaving strange in the last week(s). They randomly turned off and on again which lead to a power outage of the connected devices (e. g. PC turning off, TV restarting). I have not checked all plugs, since some are not easily accessible, so more could be affected as well, hopefully not.
Seems to be the same problem as described here: https://community.home-assistant.io/t/tp-link-kasa-hs110-switch-off-randomly/249906
I unplugged them and now I can't connect them (or factory reset them) anymore. I also hear some kind of electrical sound wgen plugging them in. I guess this is the same problem as described here: https://community.tp-link.com/en/home/forum/topic/191448
What can I do?
I use a Fritz Box as a router and had no problems so far.
I also use Home Assistant and, of course, this could be related to these firmware "updates". I did not do them actively, so this might not be related at all.
