Well I am working on the raspberry pi... as a mechanical engineer programming isnt coming natural to me. C++ is ok, python is harder... Troubleshooting now.... thermocouple readings are off....think the ADS8495 is bad)

BUT for about $10 I already have a decent readout.

If you want a readout in C vice F you can do it for a little cheaper.(but i dont think in C)

and this is the probe:

Some scrap wood and here is the result, very temporary for now. Room in the box for the pi whenever i get that running...

That's awesome and looks great for an insert. If it had a settable alarm function it would be perfect.
 
I think thats commercially available for cheap. something like this. $15.

That has a PID controller in it, no idea how that would actually be implemented on a stove... but I guess you could just ignore it and have it monitor the thermocouple and act as an alarm.

I am still looking for remote monitoring, so thats not for me. Even my current setup is only a quick setup until i get around to getting remote monitoring.... 2 little kids and a job sure slows that down.
 
Just joined the forum and this is my first post. I just built a damper control with the Raspberry Pi and have it ported to my computer and cell phone. Still building the blog for the how-to guide, but here's a teaser video with link to my blog...

This is for a small fireplace insert that I burn nearly continuous during the winter. Interested in any comments that the forum might have. Link to blog: https://smartstove.blogspot.com/

Thanks,

Welcome. Thanks for sharing. This is great stuff.
 
Thats great, first project with a linear actuator i have seen so far, i like that. I have managed to get my raspberry pi to output air temperature to a web server. I havent been able to get it to read a thermocouple... Even usint the sample sketches for the chips dont work. Literally been wasting months on this. As best as I can figure out, I have managed to buy 3 MAX31855 which are faulty.... if they are wired right and cant work the sample sketches..... its got to be right...

I havent rules out the common denominator (me) yet....
 
Hahaha, Maverick that's the same thing I told my son - it would have taken me weeks. He looked at my code for a few minutes and figured it out. If you could post your code somewhere, he or I will take a look. Or you could use the MAX6675 like I did (for $7). Either way, the serial input on the Pi or any other device is not all that straightforward.
