Same here, bought my PB1150PS2 two weeks before thanksgiving at lowes in northern cali.. "S" will stick at 180, but if you setup 225 or 250, it wont get above 208-215... its been a nice 65-70f and no wind.. but it'll keep 300+ totally rock solid. I called and the rep sounded confident that a new PID would fix it.. now its on backorder 4-8 weeks. Also the SmokeIT app is total garbage, don't even waste your time.
