IMO, you should still use an ATMEGA mcu(like a pro mini) to handle the PID/probes with HM code....you can then tx/rx with your esp8266 for remote access. I've tried/changed the HM code to support two SPI connected MAX6675 with success..(could support up to 4 thermos).... ESP8266 is still...

if you already have the esp8266 connected to your HM, why not try the express module software I wrote out....wouldn't hurt to try it first....if you need help, feel free to ask......heres the github link (binaries are there as well)...

I think I may try it out as well with HM.....but I wouldn't trust myself with DIY 1500w/15A SSR wiring...I like my house warm, not burnt ;) I found this device which looks like it would work off the servo wiring in HM....does HM have servo full on/off only mode? Adafruit also has a huge...

hardware question....could I use pin 8 (IRQ pin 4 from atmega) from the ICSP header as the 'switch' input? would obviously still need to change the HM code to have IRQ as input and trigger the lid open event.....

neat idea....did you add/think about adding a pump to circulate? I know some have mentioned the hot spots without one. Are you using multiple probes or just one for the water temp?

I think I'm going to not emulate the left button press.....the tilt switch connected to probe 4 would be more accurate(and don't have to mess with the standard board)....I also wanted to stay away from the heat, so didn't want anything near the lid (hinge for my smoker is a few inches away) so a...

Don't know if it's been discussed before...but I was 'thinking' and thought it would be pretty easy to use a cheap tilt sensor on the hinge of my kamado to detect/trigger a "lid open" event. Here's a sample of simple device.... I guess we could even connect it to a probe input (2.5 mm male...

my plan was to smoke this weekend (a 12hour pulled pork).......NOT going to happen....in the oven in goes :( (CNN)An Arctic surge will bring bitter cold air to the Northeast this weekend, with record low temperatures expected. More than a dozen states are under wind chill advisories or...

FYI....full source for project is now on github: https://github.com/nailbuster/EspressModuleHM I've also updated EspressModule for HM to v1.1: It has latest HM Setup/config changes....Servo Ceiling, Max Startup, Fan Floor...

working on the dashboard a bit more. discovered that thingspeak stores historical data 'forever' for now it seems. So I've made a history charting page to browse your history cooks from the site. I also added an easy 'share link' or 'share image' button so that you can share a history cook...

oops....had a typo in the dashboard html that was treating 10 seconds as 100 seconds, so it was slow to update.....dashboard file is fixed, so you should see your updates...let me know.

Im using windows 10/chrome as well....are you using it via the web or are you using a local file? The config form on dashboard has the interval to refresh....should be 10 seconds.. also, works in IE for me....but I'm using the the url http://www.nailbuster.com/thingspeak I know that local...

looks good....although it doesn't make a difference....was there any reason why you 'turned' the nodemcu so that the logic pins are away from header? forgot to mention that the prototype boards I used was from this pack.... let me know how the testing goes.....

Espress v1.0 NOW RELEASED!!!! I'm happy to release a version for anyone to try out today... Download the Espress for HeaterMeter Software here. Read the include PDF on how to setup your Module to work with HeaterMeter. Features include: Super Easy to configure! You simply use your...

those are nice gauges as well....I prefer the 'simple' google ones, but those do look sexier! good thing is that it would be super easy to change the dashboard to use whatever theme/gauge/chart you want.... Also, forgot another important update. ALARMS are now implemented too....You can set...

Some Espress updates: Now supports flashing an AVR(optiboot) via wifi....allows to update AVR via webinterface. Now supports OTA(over the air) flashing of the esp12 module itself....you can now update the espflash(software) via webinterface upload (that way once it's inside the HM box you...

for hanging....magnets may not be the strongest. I'd think a plastic female/male part that uses "keyhole plates" idea would work stronger.

great work! thanks for sharing.. ...just a thought.....I'm thinking in another version could serve two purposes....a couple of 'hooks' on the back of the legs (or maybe even the bottom legs) can be used to 'wrap' up probes/wires when not in use....cord wrapping stand ;)

actually, I have a similar idea for an all-in-one....you can follow my 'mini-build' here : http://tvwbb.com/showthread.php?63384-my-all-Thermocouple-HM-min-build I use Arduino on the ESP with success....however, I'd stay away from getting a A2D chip to read probes and such. ESP is great for...

..how about instead of a smiley face, you use a 'smirky' face.....where the width of the opening is different along the arc to compensate for the errors.....you would lose total opening area but should not have any errors...... and of course this is all super-over-kill......that's what makes it...
