Well, TP Link have never been trustworthy. Cheap and trustworthy rarely exist together.
I have the best smart plugs I could acquire - Kasa brand. They're great adapters, but the moment their API call doesn't get a response from their servers, they restart themselves every ten minutes. We all have to make some sacrifices in the journey to net security and independence, and keeping their API unblocked is one of mine.
If anyone wants smart plugs for monitoring purposes the Kasa brand is operable without the TP-Link app. Tapo is far worse. Never go full Tapo.
