Hey all, I am starting to get the parts to build myself a wireless thermometer probe for my GMG. It is going to have somewhere between 4 and 12 probes available (depending on which circuit board I buy), wifi, SD card for data logging, web page for probe temp status, ability to calibrate probes and ability to send emails either at regular intervals or when specific temps are reached. I am also looking into near realtime graphing via a web browser. I have two questions. 1. Does this cover everything that is pellet smokers need? 2. One of the probes I am going to set up is a sonar to test emptiness of the hopper. On my GMG if I put the probe on the bottom of the lid, there is about a 1/2inch between sensor and a full hopper and abot 5 inches at the time I need to put more pellets in. Would these thresholds be the same for a Yoder, Traeger or RecTec? Sorry for the long windedness, I am thinking of making a few extras to sell if this comes out ok. Thanks all for your help.
