I'm finally taking the plunge on the heatermeter. I have good deal of experience with microcontrollers Arduinos, RPis, though I really spend more of my time now building guitar pedals, I really love the analog stuff, and I do play. So I bought the 4.2.4 board, and stuffed it will all the parts I have on hand. I've gotten pretty far. I also had a few RPis laying around unloved, so one is being used here. So thats me, and where I'm at. How about a few questions?
There are a lot of configurations available. I think want to go for 3 probes, and one thermocouple, but is there really any advantage over using 4 probes? Seems like the surface mount parts are going to be a pain, and I can use a probe for a grill temp sensor anyway right?
Ambient temp? Where do I put the thermistor? Also, does this mean I'm giving up a probe? If so I'll skip it, but if its free to add, I would like to add it.. I just don't see where.
ICSP and FTDI connections. Any reason to solder these up? I have an ICSP programmer, and an FTDI to USB adapter, but I don't think I'll need them, the software seems pretty mature.
Oh and lastly the 4 way "button" the part on the heater meter BOM is obsolete, anyone have a spare, or can recommend a replacement part #?
Anyway, just pulling parts from the bin... only spent a few bucks for the board I've made it this far.

Thanks in advance for the feedback. I'm pretty pumped about having a proper controller for my 22.5" WSM. I want to be sure what I need before I start ordering... $5 to ship a 3 cent part... you know how that goes.
