Don't buy internet connected appliances.
No, I'll just use the remote.
An acquaintance was telling me about the new RV she and her husband bought. It has a brake controller for trailer brakes. Not unusual, I have them on two of my vehicles; there's a big lever to manually apply the brakes and a "gain" control to adjust how rapidly they apply. But her RV's brake controller is only controllable through a smartphone, apparently.
A few years ago I went to the store to buy a new alarm clock. All the clocks they had for sale were just Bluetooth accessories for a smartphone. Not particularly useful when there's no smartphone to link to it, and ignoring the question of why you wouldn't just use the phone's alarm instead.
Or that a potential fault won't be identified and the owner won't be alerted.
There are risks on both sides. But, in the UK at least, there are several inverters which don't require an IP address.
