For me it is a good time to improve security at my household.

I am working now on moving all my devices at my household to wpa3. All devices which do not support wpa3 are on a way to the second hand market or garbage bin. 
I was positively surprised to see all my kasa devices which I purchased within last few years support wpa3. Good job Kasa.

My current garbage bin collection:
a few android devices prior 5.0 (anyway it is a time for that antique devices to go)
Amazon echo - all devices - such a shame for company as Amazon, and I just updated the line last Xmas
A few cheap Tuya devices from Aliexpress
4 years old smart plug from BestBuy
Honeywell newest and the best T series thermostat, but Honeywell support asked me to wait a month or soo and try a new software. I will give it another chance, maybe
