    How do I change the Heatsnob to Farhenheit? Also how much of the probe should be in the bean mass? I did a roast today and I have the probe set really low in my breadmaker to ensure that it stays within the bean mass and I can only have about 4-5mm of the probe in the pan to keep it from getting hit by the mixing paddle, and I only hit 141 Celsius during the roast, despite hitting first crack at 6 minutes. . .

    Thanks!

    Edit the settings file:

    Documents/CoffeeSnobs/Preferences.txt

    Code:
    # Temperature scale - either Celsius or Fahrenheit.
    temperatureScale=Celsius
    You need to spell it right too!

    Probe? The tip reads the temperature but if the probe is a tight fit then it will act as a heat-sink and give you the temperature of the metal it's going through.

    You can also use the "multiplier" in the preferences file to calibrate your setup... or calibrate the probe to boiling water.

      Not user adjustable but they are 1-100 so you can plot percentages... which is also perfect for plotting manual Behmor buttons as P1=0% P2=25% P3=50% P4=75% P5=100%.

      The comments field allows you to type something in, it gets tagged on the primary plot line and also added to the CSV file so you can see/use it later.

      You can also change the value of the 5 buttons if its something that you find yourself typing a lot. In your example it might make sense to have a button called "P5 Manual" instead of "Rolling Second Crack" and that way you can plot on the line when you use it.

      Yep, that's covered in the Preferences.txt file ( My Documents/CoffeeSnobs/Prefferences.txt )

      Code:
      # Colour of template display (RGB 0,0,0 to 255,255,255).
      templateColours=0,128,0 0,100,0 0,128,0 0,128,0 0,128,0 0,128,0 0,128,0 0,128,0 0,128,0
      If you want it to be blue then change the first set of RGB number to 0,0,255 eg:

      Code:
      # Colour of template display (RGB 0,0,0 to 255,255,255).
      templateColours=0,0,255 0,100,0 0,128,0 0,128,0 0,128,0 0,128,0 0,128,0 0,128,0 0,128,0

        had a question via email...

        ...are the event buttons changeable
        Yes they certainly are.

        Edit this section in the preferences.txt file to have the 5 buttons become a shortcut for whatever you like.
        (my documents/coffeesnobs/preferences.txt)

        Code:
        # Text for tag buttons.
        tagButton1=First<br>Crack
        tagButton2=Rolling<br>First
        tagButton3=Open<br>Air
        tagButton4=Close<b>Air</b>
        tagButton5=Drop<br>Beans

          I'll keep an eye out in Beanbay for the probes to come back in.
          New Probes have landed and are in BeanBay now...

            I'm in Indonesia just bought 3kg roaster, classic drum. It seems having problem in temperature reading on CoffeeSnobs software (Roast Monitor).

            I noticed some alerts on Roast Monitor that thermocouple shorted to power and can't read the primary meter.



            Also there is huge disparity temperature reading between Autonics TCN4S and in the Roast Monitor. It shows right temperature while in Roast Monitor shows up in thousands degree Celcius.



            I've tried reinstall Roast Monitor but still occurred the same.
            Anyone can help?

            Thanks for the help.

              Remove the probe from the roaster and test it on your desk (insulated).
              Let me know if Roast Monitor works okay then.

              It sounds like a voltage leak on your roaster.

                the software adds the temp figure on the line every now and then

                If your temperature drops fast it will plot a blue temperature, if it rises fast it will plot a red one.


                Is there a way to turn this function off?

                Roast smoother!
                It's possible to roast with one temperature when you drop the beans in, one at the turn and one when you drop the beans out.


                I am guessing it does this to alert you if you are off your target too much

                The bottom left "Target field" will change colour to show too hot, too cold and goldilocks just right.


                I had not tried to edit/view/open the .csv files, i'd saved a roast in RM in .csv, and then tried to load it as a template.

                If you open in Excel and save it the columns can shuffle, blame Microsoft not us!
                Upload one of your saved templates (saved from Roast Monitor, never viewed in excel) to this thread so we can test it.


                Is there a video with the heatsnob and software doing a roast?
                Don't know. Is there? I think it would be a pretty boring 20 minute video though!


                Hi everyone.
                I'm reading this RML and its kinda a killer for me... I'm still learning the basics.
                2 questions. 1. Is there any way to increase the size of the ROR or rate of change axis so it looks bigger.
                2. with the smoothing - whilst 10 is the default... mine with a few roasts is showing a lot of "saw tooth". anyway/suggestion to make it smoother?
                Many thanks
                Raymond

                1: Don't really understand the question. If you are trying to change the graph scale you can in preferences.txt
                Which should be on your PC in: \Documents\CoffeeSnobs\preferences.txt
                Edit it in notepad, the temperature scale (vertical) and the time scale (horizontal) can both be changed easily.
                Code:
                # Temperatures (vertical scale) in degrees.
                minTemperature=0
                maxTemperature=300
                
                
                # Horizontal scale in minutes.
                duration=30

                2: Smoothing. Also set in the preferences.txt file. Post a saved JPG of one of your roasts so we can see what you mean.

                  I've attached a template that's not working RMTemplate.zip

                  Appreciate if anyone can help out! thanks folks.

                    Took half an hour of head scratching (and a little swearing) but I found the problem.

                    heat off, fan full

                    Has a comma in the note which then added another column to the CSV.

                    Removed the comma and it works fine.

                    ...will also talk to the developer to see if we can strip commas from the note field in a future version.
                    Till then, please don't use a comma in the note field (I think most everything else is fine though)

                        Heatsnob has gone a bit haywire, very rough line and bouncing around a lot.
                        Roasted 4 batches tonight, the first 3 it worked fine then the last it did this.
                        Have checked the leads, nothing seems to be out of place.
                        Occasionally i'll get some strange spikes that even out pretty quickly, however this time it was wonky the whole roast.

                        Any ideas?

                          I can see in your screen-shot it says what the problem is "Thermocouple shorted to power"

                          So something changed on your electrical circuit. Try running the notebook on battery should stop the message.
                          To troubleshoot, turn off the fan/heater/washing machine/aircon whatever it was on that power circuit that you turned on during the 4th roast.

                          The Heatsnob and thermocouples are good at "seeing" small voltage differences and will report leaks to earth or power. It's not a problem with the HeatSnob or probe, it's something else in your roasting setup or house. You can insulate the probe from the roaster and the problem will be hidden but finding the actual problem is a better solution.

                            Thanks Andy, i only run the laptop on battery when roasting, i'll have a closer look and make sure the wires are seated in the connectors properly.

                              Heatsnob working A.ok again, must have been a poor connection somewhere.
