Does anyone make a good one of these yet? I'd like to find something with a good app that uses WiFi and bluetooth. This would be a christmas gift for my dad so it would need to be relatively simple to use and reliable. If it's not both of those he won't use it. The idea is he could rest in his chair inside and maybe catch a nap while the remote thermometer is tracking the pit temp. Instead of getting up, he could just glance at the phone app to check the pit or it would alarm and wake him up if the pit temp was too low. I think it would need to be WiFi to get the distance needed but bluetooth would also be handy when we're cooking in places without wifi. I'm hesitant to trust Amazon reviews on this so I came here. Any suggestions?
