Setting up my smart thermostat during a reno showed me why default passwords are dangerous

Last fall, I was updating my living room and added a smart thermostat for energy savings. Like a lot of folks, I rushed through setup and left the default admin password in place. A month later, my heat kept kicking on at weird times, and I found out my home network had been probed by some random IP address. In my experience, this happens more than people admit because we get focused on the physical project and ignore the digital locks. Take this with a grain of salt, but I now treat every new gadget like a potential backdoor into my whole system. I spent an afternoon resetting all my smart plugs and cameras with strong, unique passwords. Your mileage may vary, but skipping this step is just asking for trouble during any home upgrade.

My buddy's thermostat got hacked too?

Changed all my default passwords after my own smart bulbs got weird last year. The lights would flicker and the thermostat would crank up to 80 at 2 AM. Called the company and they said someone got in through the default code. It wasn't a bug, it was a list of common passwords being tried. Spent a weekend updating everything and put the smart stuff on its own guest wifi. Now I use a password manager and a VPN for the sketchier stuff.

Disagree with the whole scare story about default passwords. Take @the_parker's buddy, for example, how do we even know it was a hack and not just a software bug? I've set up tons of smart devices and never changed a default password, never had a problem. People get paranoid and assume every glitch is some cyber attack, but most hackers aim for bigger fish. Sure, updating passwords is fine if you have time, but calling it dangerous is just spreading fear. Enjoy your new thermostat and don't let what-ifs ruin your home projects.
