Dear Artisan user group;
I have received an error I have not seen before using a Mac with the latest solfware : Sierra with a 64 bit system.
We have installed the CP210 driver with our data logger using Omron controls.
Here is a screen shot:
Modbus Error: Read float() hex() argument can't be converted to hex@line 30521
Could it be we have the wrong driver installed?
We use to use the FT232 driver but data driver was upgraded to a new model that has worked with the CP210 driver on most models (this data logger is setup for future use with Bluetooth capabilities)
Thank You;
Randy Harper
I'm relatively new to artisan. Been using RoastLogger for years but now that
I have my phidget 1048 I don't need the camera/ocr feature anymore.
I haven't been able to locate the help file or information about the
settings under Config-Device - Phidgets tab. For instance, Async check
boxes, raw data, change etc. I've found everything on the github page, but
maybe I just haven't been successful in pinpointing the proper area to look.
Secondly- I'm roasting on a Diedrich IR-24, which has a thicker J
thermocouple than the one I've hooked up to artisan, which is a K type 1/8in
I purchased here:
https://www.automationdirect.com/adc/Shopping/Catalog/Sensors_-z-_Encoders/T
emperature_Sensors_-a-_Transmitters/Thermocouple_Sensors/Probes_(with_Lead_W
ire_Transition)/THMK-T06L06-01
The temperatures are around 30 degrees F higher on the thinner K
thermocouple than what the roaster is reporting, even though my
thermocouples in the roaster are mounted next to each other (didn't want to
piggyback on BT of the roaster to phidgets)
Does anyone have any experience in this area? Perhaps the simple fact that
the probe is thinner means the readings will be different, but I do not
know. It would appear that the readings on the roaster are accurate while
the other is much hotter.
Just getting started, and appreciate any guidance.
The info you provide is very terse.
“SF6” is probably http://www.sanfranroaster.com/sf-6lb <http://www.sanfranroaster.com/sf-6lb>
And “Watlow" I assume to mean http://www.watlow.com/products/controllers/temperature.cfm <http://www.watlow.com/products/controllers/temperature.cfm>
My hunch is you maybe just connected the cables without making sure that variables like baud speed, even/uneven, parity, stopbits are all set exactly the same on both ends.
SF should be providing that info / assistance in their manuals / service desk.

I've been using artisan to control my 2k+ since it was released. I just
can't seem to find smoothing parameters that get me a reasonable ROR curve
once beans are added and the ROR decreases. It looks like the top half of a
sin curve. Marko made a posting recently to Home-Barista that blames that
on the fact that resolution of the 2k+ temperature is integer only with no
fraction of a degree. So when the temperature increases by a degree that
translates into a sudden spike in the ROR which artisan smooths into the sin
curve I see. The lower the ROR gets the more pronounced the sin humps get.
So I'm wondering if it's possible to have artisan control the hottop
temperature and fan speed while at the same time using phidgets to report
the temperature? Or do I have to scrap the whole 2k+ stuff and go with
something like the HTC+TC4C?
In v1.3, I am trying to add a button to reduce the airflow value by 5%.
Button Type is “+/- Air Flow”
In “Value” it works if I put “5” (the airflow values goes up by 5 when I click on the button) but I can’t enter a negative value “-5”.
Has the way to make a button to reduce by 5 changed? (in v1.1 and 1.2 it was possible to have a negative value)
Regards
Nico
Thought it might be a registration issue, this one should make it to the list. Sorry for spam.

Thanks Sean! This answers my electrical engineering question and the isolator should be the solution to my issue. Most Appreciated!

When you use just your battery, you're no longer tied to the mains power ground, so that noise is eliminated. It's possible to design hardware that works accurately anyway, either by cleaning up the noise or electrically isolating the sensor from the computer. You would think people design every sensor that plugs into a USB port this way, but sadly this is not the case. RTD temperature probes, pH sensor boards, and certainly many other things have huge measurement errors off USB power when a power brick is plugged in.

If I had to, I would probably just plug in, in between roasts.

Would like to ask the community if anyone has ever experienced interference with Artisan temp readings and plotting spikes when connecting the power cable on an Apple MacBook Pro?
My set-up is a MacBook Pro (2015) using the latest macOS High Sierra 10.13.4, Artisan v1.2.0 (3). USB connection to a Phidget 1048 connected to J-Type Thermocouples on a USR 3K gas roaster.
Since I have always used battery power in the past to run my Mac when roasting I have never experienced an interference problem. However, yesterday due to the long period of roasting I plugged in my MacBook. Having connected the power cable proved to interfere with the Temp Readings and Plots in Artisan causing them to veer off by as much as 30 degrees and have severe spikes in the plots. After some T&E, I was able to determine the issue was connecting the power cable because when disconnected and running only on battery power, everything returned to normal.
Some of the things I attempted in trouble shooting the spikes and temp offsets to determine the power cable connection was the culprit of the interference.
1. Plugged in the power cable to the Mac - Interference in temps and plots
2. Plugged power cable into different 110V outlets in the room - interference remained
3. Tried multiple USB cables connecting the Phidget to the MacBook w/ power cable connected - interference remained (disconnected Power Cable - interference resolved)
4. Plugged USB into all USB ports on the MacBook while power cord connected - interference remained
5. Removed Power Cable from MacBook - Interference resolved
So I am curios if anyone else has experienced this issue with their computers (specifically MacBooks)? Hoping to determine if its internal to my MacBook and is a singular issue applicable only to me or possibly an Apple design issue with the internal MacBook power connection? Or is it simply the power cable (not being Shielded?) or bad USB Ports or unshielded USB cables, or something else?
Thanks in advance for any experiences, feedback or resolutions.
Cheers,
Mike

Thanks Stinsonddog for the feedback. Glad to know I am not alone and there is a solution to this interference issue.
