Had a similar experience myself. Initially, I thought my thermostat was faulty because the temperature readings would randomly spike in the afternoon. After some head-scratching and a bit of detective work, I realized it was placed directly opposite a west-facing window. Every sunny afternoon, the sensor got blasted with sunlight, tricking it into thinking my living room was turning into a sauna.
Manufacturers do mention placement briefly in their manuals, but honestly, they undersell how critical it is. Even a slight shift in position can drastically change performance. I ended up relocating mine to an interior wall away from direct sunlight and drafts—made a huge difference. Now it's actually accurate and doesn't randomly crank up the AC when I'm already freezing.
Another thing I've noticed is that proximity to electronics or appliances can mess with readings too. My friend had his thermostat near his TV setup, and whenever he had a gaming marathon, the heat from his console and TV would skew the thermostat's perception of room temperature. Took him forever to figure out why his heating bills were suddenly skyrocketing.
It's funny how we invest in these high-tech gadgets expecting them to be foolproof, but sometimes it's just good old-fashioned physics causing the trouble...
Had a similar issue at my place—thermostat was near the kitchen, and every time I cooked dinner, it'd think the whole house was overheating. Took me ages to realize it wasn't faulty, just poorly placed. Moving it helped a ton. Curious if anyone's noticed humidity levels affecting their thermostat accuracy too... mine seems off on rainy days, but maybe that's just me?

Yeah, humidity can definitely mess with thermostat readings. Mine always seems a bit wonky during rainy spells or super humid summer days. Did some digging and found out that humidity affects how we perceive temperature—so even if the thermostat itself isn't technically wrong, it might feel off to us. Ended up grabbing a cheap hygrometer just to keep an eye on things... helps me adjust settings without overspending on fancy gear.
I've noticed something similar, but in my case, it wasn't exactly the thermostat itself getting thrown off by humidity. Instead, I realized that high humidity just made the room feel stuffier and warmer than the thermostat indicated. It drove me nuts for a while—I kept fiddling with settings thinking there was something wrong with the device itself.
"Ended up grabbing a cheap hygrometer just to keep an eye on things..."
That's actually a pretty smart move. After going in circles with my thermostat settings, I finally picked up one of those inexpensive humidity monitors online too. Turns out my thermostat was accurate all along; it was just my perception of the temperature that shifted on humid days. Now I just adjust my AC slightly lower on rainy or muggy days, and it's made a big difference without needing any fancy upgrades or new gadgets. Sometimes simpler solutions do the trick...

I went through something similar last summer. Kept thinking my thermostat was faulty because the house felt way hotter than it said. After days of frustration, I stumbled onto a forum post suggesting humidity might be the culprit. Picked up a cheap hygrometer, and sure enough, humidity was through the roof. Now I just tweak the AC a bit lower on muggy days and things feel way better. Funny how we always assume it's the tech that's off, not our own perception...
