First Use

When you plug-in the Heatsnob the first time (or into a different USB port) 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.

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.

FAQ
Some previous questions and answers in the order they were asked:

How do I change to Fahrenheit?

Edit the settings file:
Documents/CoffeeSnobs/Preferences.txt

Code:

# Temperature scale - either Celsius or Fahrenheit.
temperatureScale=Celsius

--------------

Is there a way to manually capture other values

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.

--------------

Is there a way of loading the csv file with the colours active?

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

------------------

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

-------------------

Error message:
Thermocouple shorted to power or Thermocouple shorted to ground

Every single instance of this error in the last 4 years has been a problem with the devices connected to the HeatSnob, not the HeatSnob itself.

1: Dodgy laptop power supplies - try running on battery and see if the problem goes away.
2: Dodgy roaster wiring - fix it!
3: Something dodgy on the same electrical circuit as the roaster or the laptop - any device misbehaving and leaking voltage to ground.

Clothes dryer, air-con, compressor, pop-up toaster, mobile phone, fluro-lights and even a vibrating exercise platform have been found to give off voltage on the same circuit. If you can't find the suss device in your building, then try insulating the probe from the roaster and see if it improves.

-------------------

The software adds the temp figure on the line every now and then, is there a way to turn this function off?

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

--------------------

Can you change the graph scale?

Yes, edit in notepad:
\Documents\CoffeeSnobs\preferences.txt
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

------------------

What size probe suits the Behmor Roaster?

The 25mm will work fine and will just protrude into the chamber but most people use the 100mm one to get it further into the roast chamber.

The Behmor template in the first post here shows a 3mm hole through and a 4mm hole in the cover, this was true for the older 3mm probes. If you have a more recent probe it's likely to be a 4mm wide probe and will require a 4mm hole through and 5mm hole in the cover.

-------------------

Where to install the probe in a Corretto?

See: HeatSnob Chat for a great picture and discussion.

-------------------

Where to install on my xxxx roaster?

Bean Mass:
On my commercial roaster that's near the sight glass where the beans are moving slowest and have better contact with the tip of the thermocouple.

Air Temperature:
On my commercial roaster under the drum shaft is a good place to measure heat without bean contact.

Exhaust:
Anywhere, the temperature measured here will be specific to your setup but will still show you if you are running hotter/cooler than your target.

------------------

Where to install the probe on a Hottop?

The 100mm probe has been installed in the back end of the Hottop drum before.

------------------

How many HeatSnobs can I run?

The software has a limitation of 9 HeatSnobs which should be plenty and I look forward to knowing what setup needs more than that!
Each HeatSnob needs its own USB port on the computer and they will run fine on a USB hub if needed.

------------------

Can I run the Roast Monitor software without a HeatSnob attached?

No, the software needs to see a HeatSnob plugged in before it opens.

------------------

When I double click the RoastMonitor icon nothing happens

1: Make sure you have installed Java (see post #1 above) and restarted your machine.

2: Your windows file association for .JAR might be wrong. WinRar can take ownership of .JAR files and cause this,
Manually fix the association in windows or download and run the excellent little file JARFIX.EXE to fix it.

------------------

Java - EXCEPTION_ACCESS_VIOLATION (0xc0000005)

Only ever seen twice and was fixed with a simple uninstall and reinstall of Java.
The best Java version to use is called "Windows Offline" from https://java.com/en/download/manual.jsp

------------------

If you have another problem post details here and we'll troubleshoot it ASAP.
We have never had a Windows machine this doesn't work on.

**Andy** · 26 August 2020, 06:25 PM

(Thread clean-up, previous troubleshooting has been removed and the FAQ in post #4 above has been updated to keep this thread readable.)

Version 2.64 available now.

**crazyhakins** · 21 December 2020, 11:47 AM

Is there a way to change the range of the RoR curve? So, instead of showing a 1:1 ratio it had a 1:3 or 1:4 ratio so that it’s easier to see changes on the RoR curve? I don’t mind if it overlaps with the bean temperature curve, just would like to be able to see RoR changes a bit easier.
I’m using Roast Monitor on parallels.

**crazyhakins** · 27 December 2020, 01:53 PM

I use the plot heavily during roasts to help me anticipate what’s about to happen in a roast, it’s also great for identifying patterns and adjusting roast parameters etc. it would be a really cool feature to be able to edit the graphing ratio. I’d love to see it in a future iteration one day!!

**Buzztruck** · 20 March 2021, 11:12 AM

Hi can someone please give me a link to software so I can plug my multi meter in and start using on my new roaster ? I'm new to this 5kg roaster and was told there is a free download on here ? Thanks

**allinone** · 22 March 2021, 12:50 PM

This datalogger looks interesting and the documentation is terrific GrahamK . But a simple question about the "HeatSnob Temperature Data Logger and the various thermocouples.

Can the data logger be powered by a battery pack USB and will it record temperatures and store the data internally for later download?
Thanks

**Buzztruck** · 22 March 2021, 06:16 PM

I down loaded the profile thing tried both but I only get some script not the program ?

**Buzztruck** · 29 March 2021, 06:34 PM

I still can't get this to work with my multimeter even my computer bloke has no idea or do I have to buy the $80 monitor ? Thanks dale

The program notes and manual are terrific but some minor details are missing. PM me or contact me for specific installation assistance, as mine installed with some easy scripting changes. But I use a Windows laptop and not a multimeter as my multi meter is not a USB type.

**Buzztruck** · 22 April 2021, 09:31 AM

How can I buy 1 of these monitors ???
