I have all of the parts I need and am finally starting my PID temp controller build. My birthday is next month and I want to do a brisket, but don't want to be up all night again. I'll post pics tomorrow, but for now it should work as follows:

Temp control via a Thermaltake smartfan, high/low temp alarm (indoor and outdoor), A/C power fail alarm, meat temp reached alarm (if I can get the voltage divider circuit and OP amp working), lid open fan disconnect, PID shutdown when meat temp is reached.

I should have the whole thing running except for the indoor alarm and possibly the meat temp reached alarm and shutdown. I built an OP amp circuit today to boost the beeper voltage on my thermometer to a high enough voltage to trigger a delay timer relay that will power the alarm, but didn't get to test it yet. It should work, in theory. I also wanted to power the meat thermometer from the 12vdc power supply and avoid the batteries, but haven't got the voltage divider quite right. I need to drop the 12vdc to 3vdc for the thermometer.

If all goes well tomorrow, I should be good to go. If all goes poorly, I will get electrocuted or burn the house down in really spectacular fashion.
