It shouldn’t be a tech purchase but our Bosch refrigerator. Our options were limited during the pandemic so we got the smart one and the setup process was so bad that it should’ve been a warning: they cheaped out and didn’t put Bluetooth on it so you have to let it be a hotspot, connect with their mobile app, give it the password for your device network, etc., all with lowest-bidder unreliable software at every stage.
After all that, it turns out that they didn’t do anything useful: no way to even see the current temperature and after a high temperature alert, there’s no way to see how high it got for how long. They advertise remote support but the one time it came up, it turned out that was completely fictitious and they insist on sending a technician.
I bought a Mi Smart Kettle Pro and the "smart" features are really pointless. You can change a couple of settings, which they could have just made button presses on the device. I thought you'd be able to schedule it to boil, but you can't do that or even turn it on from the app.
I don't care too much though, as it is stainless steel inside and was cheaper than the equivalent dumb Philips kettle.
