Darren, When you POST to the login page, you will also get a path cookie back that has the stok=x value. Might be easier to pull that value out of the cookie instead of screen scraping. Also, if you issue a GET request to /luci/lm/hmstatus you will get pretty much what you are looking for...

I haven't gotten lazy yet (only a few weeks of use).. But: My wife and family have been making fun of me for my test cooks with no meat They are getting tired of me showing how I can control my cooks via the web / iPhone. I'm borderline obsessive compulsive watching temps and the PID...

My goal in the next few weeks is to put together a front facing www site to point everyone. That www site will also poll the heatermeter for updates as well as keep all the historical updates and settings. I started a test cook a few hours ago and the results have far exceeded my expectations...

Success! I'm up and running!! Feel like a kid in a candy shop with $500 in my pocket! I'm online and working: http://fivewilliams.net:8000 Just need to build a fan assembly/case now. Thanks *so much* for all the hard work and effort put into this project. Hopefully I'll be able to...

I did test and the fan works fine. Taking a closer look, I'm almost positive that I put the MOSFET in backwards. Looking at the assembly pictures, the flat metal part (heat sink?) lays flat on the PCB? If I did put it in backwards is it now toast?

I'm now running power to the blower via J4 and when I measure the voltage I'm getting around 8.4-8.5 volts. When I connect the blower, it doesn't work. After I remove the blower, and check with my multimeter, I don't see any voltage. MOSFET power supply bad? I'm using a 12v 1.5amp wall wart...

Sorry for being cryptic! In more generic terms, how can I troubleshoot why I'm not getting power to the blower when I'm supposed to. I thought that measuring say the inside of the barrel against the outside of the barrel would give me 12v. Is that correct and if so, what can I measure to...

Thanks Bryan! One other question; before I blew up my rPi, I was not getting any voltage to the blower via the RCA jack. I did measure 12v on J4 when going to the ground of Q1/MOSFET. However, I wasn't reading 12v on any of the other RCA connectors. Am I missing something? Also -- I see...

All, Not sure what I did, but in the process of troubleshooting why my blower wasn't working I shorted out my rPi :( Fortunately, I have another rPi but before I go plugging this one in, I want to make sure I haven't messed anything else up. I've checked the voltages from the gpio connector...

Quick update -- looks like I had multiple problems which ended up being a good thing. I did yank out the GPIO header, flipped it to the other side and voila! Everything powered on, the Pi recognized the board, everything flashed and looks good. The other problem is that I wasn't paying...

Hi Bryan, thanks for the response. Unfortunately, I'm not talking about the LCD; I am talking about the GPIO connector between the heatermeter and the Raspberry Pi

First, thanks everyone for this awesome project! I've been looking forward to building the heatermeter/raspberry pi for a long time now. So I followed the build instructions with some small changes as I have a case in mind to house everything. My plan was to use an old floppy drive cable I...
