Haha, YouTube tutorials always skip the part where you're cursing under your breath and hunting for dropped screws... I once spent hours installing a "simple" smart thermostat, only to realize I'd forgotten to turn the power back on. Happens to the best of us.

Yeah, I feel this one. Those tutorials always seem suspiciously smooth—makes you wonder how many takes they actually do before uploading?
Anyway, about the thermostat issue—what exactly do you mean by "acting weird"? Is it randomly changing temperatures or just not responding at all? Did you double-check the wiring connections? Sometimes a loose wire can cause intermittent issues. Also, have you tried resetting it to factory settings? Most smart thermostats have a reset option buried somewhere in their menus, usually under settings or troubleshooting.
Another thing to consider—did you update the firmware? I know it sounds trivial, but outdated software can cause some pretty strange behavior. Had a similar issue with mine last year; it kept randomly shutting off until I finally realized there was a firmware update I'd missed. Took five minutes to fix after hours of frustration.
If none of that works, are you comfortable opening it back up and checking the wiring again? And importantly, do you have a multimeter handy? Checking voltage at the thermostat wires can tell you quickly if it's a power supply issue or something more complicated.
Honestly though, if you've already spent hours on it and it's still giving you trouble, sometimes biting the bullet and calling a pro saves you more headaches (and maybe even money) in the long run. DIY is great, but there are limits...
Yeah, checking voltage is solid advice, but honestly, thermostats can be finicky even when wiring checks out. Had one that randomly jumped temps—turned out to be a faulty sensor. Ever thought about swapping out the thermostat altogether? Sometimes it's just easier...
"Had one that randomly jumped temps—turned out to be a faulty sensor."
That's a great point. Thermostats can indeed behave unpredictably even when wiring seems fine. I've encountered similar issues myself; spent hours troubleshooting wiring and voltage only to realize the thermostat itself was faulty. Swapping it out can save a lot of headaches in the long run, especially if you've already checked the basics. Good call on considering replacement—it might just simplify things considerably.
I've run into thermostat issues like this before, and honestly, sensors can be sneaky little things. Before you jump straight to replacement though, have you tried giving the sensor a quick clean? Sometimes dust or grime buildup can cause weird readings. Just gently wiping it down with a soft cloth can do wonders.
If that doesn't help, you might want to test the sensor itself. Grab a multimeter if you've got one handy, and check the resistance readings at different temperatures (you can find charts online for your specific thermostat model). If the readings are way off, then yeah, swapping it out is probably your best bet.
But hey, don't beat yourself up if you end up replacing it anyway. Thermostats aren't always as straightforward as they look, and troubleshooting can be a bit of trial and error. Sounds like you're already on the right track though—good luck!
