TP-Link Kasa Matter Smart Plug KP125M

The plug for a setup that has to survive a change of phone, partner or flatmate as well as a change of address. Matter certification means one plug works with Apple Home, Alexa, Google Home and SmartThings, and it keeps responding over your home network when the internet drops. It is rated for 15 A, so it copes with more than a bedside lamp. Energy readings stay in TP-Link's Kasa app rather than appearing in Apple Home, and it only joins 2.4 GHz Wi-Fi. Engadget's tester also found the Apple Home connection unreliable until a HomePod mini was added as a hub.
