    HeatSnob Temperature Data Logger Thermocouple and Roast Monitor USB software

    HeatSnob - Accurate Temperature Monitoring

    The CoffeeSnobs USB Temperature Data Logger has now been replaced by a smaller, neater device called HeatSnob.



    HeatSnob works with CoffeeSnobs Roast Monitor software and Roast Monitor will work with a mixture of HeatSnob units and the previous meters. You can run up to 9 temperature monitors although 2 or 3 is enough for most people. Bean temperature, air temperature and exhaust temperature are the 3 most common areas to monitor but you could also add cooling tray or ambient temperature if you can use that data too.


    This meter and software has been installed on 1000s of different PCs all over the planet and everyone I know that run it are getting much more consistent results using this logging and replicating.


    Tested as working well on:
    • Win98SE
    • Windows XP Pro
    • Windows XP Home
    • Vista Business
    • Windows 7 (32bit)
    • Windows 7 (64 bit)
    • Windows 8
    • Windows 10


    Mac? I have been told that it works fine using Parallels for Mac.
    (We still suggest you are far better off getting a low-end PC which will run this fine)

    Not working well on:
    • VMware (suffers from disconnections during the roast)
    • Linux. Sorry, but I doubt it will run on Linux until Sun Java gets a working USB library for Linux, Mac and Windows.


    You can scrounge an old PC for next to nothing these days. *The hardware requirements of the software is very low and it will run on just about any Windows PC with a USB port. *Finding an old notebook (with 1024px resolution) is often a great way to use this roasting tool.

    This is a true plug and play hardware device, Windows automagically loads its own driver for it and it appears in Device Manager as a HID without mucking about with serial device driver files and having to know baud rates and com ports.


    Where to buy?

    The USB Temperature Datalogger is available in BeanBay "Other Stuff" now.
    CoffeeSnobs - BeanBay - Other Stuff - HeatSnob Temperature Data Logger

    Software Download

    You can get the Roast Monitor software V2.62 (MAY 2018)
    (RoastMonitor.exe - 2666KB) for this meter from:
    http://coffeesnobs.com.au/RoastMonitor/Roastmonitor.exe
    or if you need a ZIP file then use:
    http://coffeesnobs.com.au/RoastMonitor/Roastmonitor.zip

    After downloading, run the installer and follow the simple prompts.

    The installer will:
    * Place a Roast Monitor icon on your desktop
    * Install into Program Files (x86)
    * Saved profiles, logs and preferences will be under Documents/CoffeeSnobs

    This will make future updates cleaner and easier, leaving the previous profiles and settings and only updating the program.

    Roast Monitor uses Java for the display, if you don't have Java then you need to download it from Oracle (free download): Download Free Java Software


    Roast Monitor User Guide

    This excellent user guide was put together by CSr GrahamK for the older meter version but should help new users and existing ones get up to speed with the features pretty quickly.
    450Kb Word Doc.
    http://coffeesnobs.com.au/RoastMonit...User-Guide.zip
    Thanks Graham* 8-)

    Revision Notes:
    Detailed revision notes are included in the download.

    Troubleshooting
    • Nearly every problem reported in the last eight years was fixed by downloading and installing current versions of Java


    This would be a great time to remind people that this software is written for me to use with the commercial roaster at the Snobbery and it has been working perfectly for up to 50 roasts per week, every week of the year for years.

    While I'm happy to share it with CSrs for free and welcome new ideas please understand that if I cannot see a benefit in a requested feature or think it would hinder my usage then I won't want it in the software.


    A template for mounting the stainless thermocouple in the Behmor1600 is below.

    Outside of Australia?
    HeatSnob is available to other countries via HeatSnob.com

    Please Note: we will clean this thread from time to time and update any new information in this first post to avoid confusion when a new version is released.

    Troubleshooting.

    When you install the Heatsnob the first time Windows will try and find a "plug 'n pray" driver for it.

    You should see the installation icon the bottom right of the task bar, opening it will show the following.


    1: It will try and get an updated driver for "HID Thermocouple" from Windows Update, you can wait for the time-out or better still, click on "skip obtaining driver software from Windows Update"






    Because Windows never trusts you, it will also ask you to confirm the click. Answer Yes.




    It will then go ahead and install the driver you already had on your machine.
    You can click Close when it's done.

    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'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.

    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.

    20171114-FIXED.jpg

    ...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)

    Those with a keen eye might have noticed in my above picture that I was running version 2.61
    I've been running that live on my roaster for more than a month and can't find any problems so it's now gone live and the download links in the first post will be for version 2.61 now.

    Version 2.61 is our first multi lingual version.

    We have lots of people running this all over the world and while they have learnt our english roasting words, they shouldn't really have to. Now they can set their own words in a simple text file called Translations.txt



    Extract from ReleaseNotes:
    Revision 2.61

    1. User-customisable text

    All text in the main window can now be customised by the user.
    On the first run of RoastMonitor, the file "Translations.txt" is created in Documents\CoffeeSnobs. This file contains a line of the form "English text = English text" for each text element in the main window. The text to the left of the equals sign should not be altered, but text to the right can be modified as required. If modifying this file, you should be aware that this file is Unicode-encoded.
    Text on buttons can include some HTML tags. A text character surrounded by <u> and </u> will be set as a keyboard shortcut for that button; <br> will force following text to a new line.
    For consistency, the previous customisation of some buttons via Preferences.txt is no longer supported.

    ---------------------------------------------------------------------------------
    If you want to see translation in action, replace Documents/CoffeeSnobs/Translations.txt with the below spanish content. When you've finished playing you can delete Translations.txt and a pristine version will get created next time you run.
    ---------------------------------------------------------------------------------

    <u>U</u>nload<br>(Cool) = Descargar<br>(<u>F</u>rio)
    I'm happy to keep a library of translation files either here on CoffeeSnobs, on HeatSnob.com or in the software package so if you make one you like, let me know.

    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.

    V2.62

    When we moved the forum from HTTP to HTTPS we "broke" the Roast Monitor version check.
    All fixed in this version.

    Download version 2.62 from the links in the first post.

    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.

    Again, please read post 16 above.

    Shorted to power error message really means that the HeatSnob could see a problem, not it had a "poor connection somewhere".

    Clothes dryer, air-con, compressor, pop-up toaster... something on the same circuit is "leaking" power sometimes. Don't be surprised if the problem comes back and it's not the HeatSnob causing it.
    You can easily identify what else is on the same power circuit by turning off that specific power circuit at the electrical meter and then seeing what doesn't work in your house.

    HeatSnob Temperature Data Logger Thermocouple and Roast Monitor USB software

    Hi Andy, thanks I understand however I don’t have the computer plugged into the mains when I roast so don’t believe this could have been the issue?

    The roaster is plugged in of course, could another appliance be causing an issue through the roaster power? In any case I’ll keep in mind to turn of any other appliances in future if it happens again

    Yep, it was my wife's vibrating exercise platform, she turned it on mid way through a roast last night and the readings went haywire. Thanks for the assistance.

    Nice to know I know what I'm talking about (sometimes at least). Those symptoms are always a different appliance on the same electrical circuit as the HeatSnob computer.
    I do appreciate you letting us all know.

    You might want to get the "vibrating exercise platform" looked at by a sparky. It might be a suss plug-pack or similar that's leaking voltage that the Heatsnobs sees. Better to be safe than sorry.

    Thanks I’ll look into it. For the record, the computer is not plugged in to mains while i roast, only the roaster is plugged in.

    Maybe!?!?
    Not enough information to give a better answer. Most "normal" multimenters don't do temperature, if your multimeter does temperature then its likely but not guaranteed the probe will work.

    Yeah, think I'll just get the heat snob. I've got an old PC kicking around too.

    I'm using a correto setup. Is there a 'best position' in the bread maker?

    Probably stick with any of the well known brands such as Breville, Sunbeam, etc...
    Lots of CSers use these so can be helpful if you need to seek advice about setting up, problems, etc...

    I have a feeling crazyhakins meant what position is best for the temp probe hehe

    I tried installing the heat snob thermocouple into a Behmor 1600 plus , with Andy's original instructions (drill 3mm hole all way through, drill 4mm outer case only), I couldn't fit the probe in. The probe itself is 4mm diameter.. but that means it won't fit though the 3mm hole inside the chamber... am I missing something here? and how is the probe fixed onto the outside case with the m6 thread? I currently have the long probe 100mm, should I order the short 25mm probe?

    justacuppa, I have three probes here (2 x 100mm and 1 x 25mm) and upon measuring all seem 4mm. Maybe the probe size has changed since the instructions were written? Would just drilling the 3mm hole out to 4mm be the way to solve the problem? Maybe a 5 or 5.5mm in the outercase and either tap or use the probe to tap an m6 thread?

    Bang on. I was wondering if Andy or anyone else had installed one on a coretto and where they placed it to get a good reading?

    I still have a corretto but not in use. It has a modified Breville single loaf bread maker and I drilled a hole through the side and into the corner of the square based pan where it is least likely to be hit by the agitator. I had to use a 100ml thermocouple (TC) and the probe projected about 15ml into the bean mass and about 5 ml from the bottom. You can see the hole in this pic



    Others have used a bead type TC fed down the side of the pan and through a hole int the side..

    The "best" location actually depends on the batch size you decide to settle on and the volume/shape of the bread-pan.

    To work this out, load up your bread-pan with beans until you notice that agitation starts to become sluggish. Reduce the batch size until vigorous agitation is restored then weigh the beans. Adjust the batch up or down until you reach a simple weight - 500g, 600g, etc. With the weight decided, put the beans back into the bread-pan, level off and mark the height of the beans on the inside of the bread-pan. Identify a location that will clear the kneading paddle plus be as far from the heatgun air blast, and then drill a hole ~30mm below the batch height level you marked earlier.

    This will give you a reliable position from which to measure the bean-mass temperature and be comparable to the majority of recordings made in drum roasters. Have determined this via a lot of experimentation and cross referencing. You can of course, adjust the vertical position of the drilled hole(s) to suit different batch sizes.

    Hope this helps...
