Let me start by stating that I have the ET-732 and I have looked at the Digi-Q, BBQ Guru, Tappecue among others out on the market but none of them have what I am looking for. Having a pellet grill, I have created a basic sonar system (in another thread) to alert me when I need to add pellets, but even this one is with flaws. I am building a new system that can alert (via text or email) me on the following: low pellets in the hopper if pit temp goes out of whack when food reaches temp graphs the progress of temp over time I have the circuit design and programming figured out for the most part. But I am stumbling on one part and would like everyone's thoughts. I will be using type K thermocouplers for the probes and the system can logically handle up to 96 probes. I was thinking of building with 16 connections in place, but only 4 probes to start. Some of those that I have spoke too think that this system is way too much and I will never need 16 probes. My question is, for 1 pit how many probes is too many? Am I going overboard building something can handle 16 probes?
