I received a grill gift / project for my Green Mountain Grill from one of my buddies for Christmas. I did not opt to purchase the WiFi model of my smoker back when I purchased but it seems that all of the controller boards are the same. The non WiFi model I have just lacks the antenna and connecting cable to the board which he purchased somewhere. So, with weather permitting, I'll be trying to hack my smoker this weekend. The WiFi works in three different modes. You can connect it directly to your phone via Wifi. You can connect it to your local network. And if connected to your local network from anywhere you can access Green Mountain's server to access the smoker. I'm not anxious to smoke meats from across town but to monitor my cook from afar has it's perks.
Things that can be done remotely include turning on, turning off, grill temp, one probe temp, low pellet alarm, raise and lower grill temps, timed cooks, meat target temp alarm, and profile cooks. (so many hours at this temp, raise to that temp for so long, lower temp or shut off etc) I can't imagine using most of the remote features but to monitor my temp from afar could prove to be a tool. I often will start a cook and then go mow a few residences, and then swing by to check my cook. Then go mow some more etc. Knowing how my cook is going could come into play. However, I opted not to purchase the WiFi model to begin with for most cooks need additional attention beyond temps as they go along.
As a Christmas gift I'll go the distance to put my smoker online. Why not play with the technology?
