to find out which probe to 'trust', you can test which one gives the correct temperature with a water boil temperature test. Water will boil around 211f.... but depends on your elevation (see chart)

The idea of the 'external board box' would have some issues. The TC +/- cables can only be extended with the same TC cable-type material. So you'd have to run data lines and a thermo couple cable to the box that has the mux/demux. IMO the best is to use SPI to a MAX TC/mux external board...

looking at that octo TC board is kinda 'neat'.... if it actually works (I found other shields/schematics online that have a TC multiplexed as well).... that would be super simple/cheap to support 4-8 TCs... Seems that it needs 125ms between switch/read but that's not too bad. You could read...

wonder if it had another probe 'tube-holder' on the opposite corner if it could hold two probes on one piece.... also, does the jack end 'snap' anywhere, or does it move freely?....

Hi FredB, For the latest install instructions and files, download this file. the zip has the esp8266 flasher for windows, that will help you flash the bin and I believe will also tell you the size of the flash.... if you have any questions after reading the pdf within that zip, you can email...

WBegg is correct... it already support 4 TCs, just have to add the extra TC units. I just chose two for now to keep the size down and I've never needed/used more than 1 food probe for my cooks.....

great! all code is here: https://github.com/nailbuster you can email me directly : david at nailbuster.com I can give you more info and answer any questions...

list looks good.... I would add a small item (if you don't already have it).... a usb power connector board, something like this: let me know when it all arrives....like that you're going to go with 4 thermocouples!!

No need for the RPi...the wemos will handle what you need....it (the esp8266) is a great little chip! I'm finalizing v2 of my espress project. It has full local web pages for graphing/local interface with no need for an internet connection if you don't want to use a cloud service.

you could try a simple 'yet - super geeky' mini build like mine:

12" probe seems long for a pit probe.....if you had one of those small ones that have an alligator clip on the end, maybe you could 'clip' it onto the top of a meat probe? That would be a cool idea....a meat probe/pit probe combo probe.... the handle of the meat probe would have a TC(or...

It worked for me....I just 'joined beta' on bottom of app page and in a few minutes was able to 'update'....

With Jason's code changes last week and a little bit of 'salt' added from me, the Espress Module is emulating the JSON so that it works with PitDroid. I just tried it out and it works. No Graphs though, I don't know the json/url format that it/HM does....

you can email me directly david at nailbuster.com and we can troubleshoot quicker/better......

if you're on 1.2, make sure you copy over the new html files as they have the feature of off-line and direct access to HM...good idea, I'll add a version to somewhere via html... BIN files are for esp8266 firmwares(those are made by the IDE compile)....AVR files are for the atmega...
