My 2019 smart thermostat did the same thing last winter, just decided the living room was 85 degrees and cranked the AC. @cameron318 is right, it feels like everything runs on beta software now. My car's infotainment system reboots at the same left turn every Tuesday. You buy a finished product but spend the next two years just hoping the next patch fixes the gremlins.

Okay, but if you're gonna correct someone's gas, maybe bring your own detector to the argument (just saying). That old mall air probably has a whole cocktail of "nope" brewing by the food court.

Ugh, that's so frustrating. I read an article last week about how screenless tablets have a real learning curve for technical drawing. The writer said it's like learning to draw all over again because your brain has to remap where your hand is. It makes total sense that HVAC schematics, with all those tiny details, would be the worst for that disconnect. Did you try any of those cursor placement exercises, or was it just hopeless from the start?
