Getting Started With Data Logging

968x601 Getting Started With Data Logging

Getting Started With Data Logging

What will I need to get started?

First, you’ll need to verify that your roaster has a thermocouple that can safely be used for external data logging. Factory installed thermocouples are usually integrated into the function or safety features of the machine itself. Since thermocouple leads cannot be safely split or spliced without affecting the voltage, and consequently altering the probe reading, it is often necessary to add a separate thermocouple for data logging, or replace the factory probe with a dual-tip thermocouple of the same type.

Second, you’ll need to purchase the Data Logging option in Roastmaster. Navigate to the Probes list of the Utilities screen to launch the Probe Store.

Finally, you’ll need to purchase the appropriate hardware.

    Danny, will the newer Phidgets SBC3 also work? Any compatibility issues you’re aware of?

    Thanks!

      Hi Ben

      Yes – it will work. The only caveat is that the v3 is shipping with a newer build of their software than the SBC2 was. Phidgets require that the version of software running on the client (Roastmaster) exactly match the webservice software running on the host (SBC). Upgrading the SBC is very easy, but downgrading is a bit more of a pain. I am uploading the next update to Apple this week, unless something pops up in testing, which will have the newest Phidget software and will link right up with little or no fuss. Hopefully the update won’t be more than 10 or so days away. If, in the meantime, you get the SBC3, just let me know and I can easily put you on the current beta build, so you can get up and running right away.

      Cheers

        Fantastic, thanks for the quick response! I’ll order the SBC3 then. Since it’s coming from Canada it’s arrival may coincide nicely with your update. I can’t thank you enough for all the work you’re putting into the app. It’s just about the best learning tool I have and it’s given me a solid workflow to anchor in as I learn how to roast. Thanks for everything you’re doing!

          Hi Ben

          Sorry, I was out of town – just got back into the office a few hours ago. Apple has approved the new update – I’m going through a little extra last minute testing. If everything checks out I’ll release it live in a few hours and you can download directly from the app store.

    Would other SBCs work with Roastmaster?

    The Phidgets combo seems rather pricey. I was thinking it should be possible with a Raspberry Pi. The Raspbian ‘Wheezy’ OS is a flavor of Debian Linux, which is what the Phidget SBC2 uses, so it ought to be compatible. Combine that with a OWFS thermocouple like this one (http://www.parallaxdirect.com/cart/catalog/Parallax-28022-DS2760-Thermocouple-Kit-253.html) and you could do the whole thing for maybe $90, instead of the $260 or more for the Phidget setup.

      Hi Glenn

      I haven’t tested it myself, but another user runs the Phidget Temperature sensors from a Raspberry Pi. He said it works fine. Managing the software will not be an automatic process like the SBC – you’ll need to install the Phidgets Web Service and set it to run on boot, but according to him everything else was straightforward. Also, you’ll need a wireless adapter if you want the combo to be portable.

      At the moment, I’m adding support for the iCelsius BBQ and the Bluetherm Duo. I’ve encountered a couple of bugs with the Bluetherm’s SDK, and am waiting on resolution from the manufacturer. If that is resolved, I plan to support both of those in the next release if that influences your decision.

      Otherwise, if you go the Raspberry route, and have questions just let me know. Like I said, I haven’t done it myself, but may be able to offer some help.

    Hi

    Apologies in advance if this has already been covered. Can you please supply a list of components I would need for using the Phidgets connection. Sorry I’m not the tech minded but would like to connect 2/3 probes to a small commercial roaster. Warm regards gianni

      Danny HallFeb 09, 2014

      Hi Gianni

      There are diagrams and parts on Setting Up Phidgets.

      I assume you’d want the entire setup (so you don’t need a laptop as a host). In that case, and for your setup, you’d need the 4-port Temperature Sensor, an SBC, the WiFi adapter and, of course, thermocouples. I’d also recommend getting the two acrylic enclosures to protect and mount the boards – 1 for the Temperature Sensor and the other for the SBC.

      The WiFi adapter on that page links to the one that works the best for the SBC2. There’s no need to get the more expensive SBC3. I’d stick with the SBC 2.

      Any more questions, just let me know.

        Hi Danny

        Thank you for your message. I now have all the equipment. I actually ended up finding and buying it before getting your msg and unfortunately I got the SBC 3 . Hope that still works. I’ve pieced everything together. Quite neat actually. Feel like I’m back working on a school project. I purchased two K type thermometers and will look at the best place to put them on the roaster. Ive got a new giesen roaster w15. Really keen to start using the program.

        I have one question. I recently put in a thermometre for the afterburner…can you join into that rather than install new ones? or is it best to install a new one?

        • Danny Hall
          Danny HallFeb 21, 2014

          Hi Gianni

          The SBC3 will be fine. It works the same way. The Phidgets site notes that one WiFi adapter is best suited for the SBC2, and the other for the SBC3. Probably mainly due to the supported network protocols – my guess is that they are completely interchangeable. But, if you notice any connection issues, it would be due to that. I haven’t tested them apart from the recommended pairing, but it’s easily fixed if there’s any issue.

          Unfortunately, no – you can’t physically split thermocouple outputs. The voltage they send out is too sensitive. The best bet would be to install a second probe, or look into a dual-probe to replace the existing probe. I’ve never used one myself, but the roaster manufacturers I’ve talked to install them in roasters they custom build for Roastmaster and other situations like this. Something like this probe. Omega is a good source for probes.

          Let me know if you have questions along the way. I felt the same way putting my Phidgets together – I really enjoyed it!!

    Hi,
    Is it working with Phidgets connected with Pt100 RTD?

    • Danny Hall
      Danny HallApr 28, 2014

      Sorry – no. The Phidget Temperature Sensors themselves do not support RTD probes. It can be done with their Bridge board and Wheatstone/RTD probes, but it’s a little more complex than standard thermocouples, and I haven’t considered it for Roastmaster yet.

    Hi Danny

    I got my icelsius BBQ probe, replacement of broken probe( of 452degree celsius) couple of days ago

    It works well now with data logging
    You made wonderful APP

    I found minimal frequency time is 10 second and it’s hard to record accurate TP

    Is there any better way to record accurate TP?

    I think 10 second as frequency time is OK but TP should be recorded precisely

    Please consider making better way to record accurate TP

    thank you

    • Danny Hall
      Danny HallJun 03, 2014

      Hi Jessie

      Glad to head you finally received the probe!

      I will likely reduce the minimum frequency when the next batch of iOS devices are out, but I have no plans to go to the sub-second level of a standalone data logger.

      Roastmaster’s scope is much broader than simple data logging software that deals with only limited data at any given time. Roastmaster makes it possible to load hundreds of roasts or more, and browse through them quickly. Since iOS devices have limited memory and processing poser, I need to impose some restraints to keep things flowing smoothly, in addition to keeping database sizes manageable.

      If you haven’t discovered it yet, probe crosshair positions, temp readouts, differential temperature projections and probe deltas all update in real-time (every half second), so this information is extremely precise.

      Again, though, I do plan to lower this threshold for persistent curve logging as device power and memory increase.

      Thanks for the feedback.

    Hi, I just set up my new Huky 500 with Roastmaster and bluetherm duo. Once I remember to do everything I should I think I’m going to like this a lot. I have 2 questions. 1. With automatic Data input from the Duo, is it necessary to choose a node time and value? What should the value be? 2. How do I delete the roasts that I’ve screwed up?
    Thanks for this great piece of work.

    • Danny Hall
      Danny HallAug 04, 2014

      Hi

      No, if a curve is bound to a probe during a roast it will automatically record node data at the specified interval (You specify that along with the C or F scale in the curve itself). Temperatures, deltas and temp projections are all live (before, during and after the roast), but the node capturing occurs in intervals when the roast is in progress. It will create one node when the roast is started, and one when it ends, and at the specified interval while in progress.

      If you haven’t seen them yet, there’s a couple of videos (Roasting Profiles and Creating a Profile from a Roast) that cover curve templates in profiles here http://rainfroginc.com/roastmaster-documentation/videos/. They talk about how to pre-configure curve bindings for data logging so you don’t have to set up curves each time you roast.

      To delete a roaster, just swipe from right to left on a roaster in the roaster list. You’ll get the “delete” button.

      Any more questions, just let me know.

      I have. Unfortunately, they aren’t going to make the software API public. I wish they would, because the mini looks very promising for a lot of home roasting applications.

    Can you record two themlerature channels? (BT and ET)

    Can this app use other Bluetooth thermocouple readers (if the iPad can see the Bluetooth recorder, the app can record the data), or am I limited to these specific thermocouples only?

    • Danny Hall
      Danny HallApr 10, 2017

      You can record as many thermocouples as your hardware will allow in each roast. Only the models listed here are supported, with the caveat that Thermoworks is only a few weeks away from releasing a BluethermDuo replacement. I plan on supporting that as quickly as I can issue an update once it hits the market.

    Hey Danny,

    Everything is solid by data logging with a wireless phidgets set up except one thing. I’ve noticed this happening mainly on the very first first of the day for some reason and it’s happened a couple times since moving to wireless.

    Partway through the roast, both temp probes will disconnect for a second, and then jump 100 or 200 degrees, and continue along those trajectories. After finishing the roast and having unusable data for the last half or part, I have to re open the app to reset them.

    Is there a way to avoid this? Or a way to correct them while roasting ?

    • Danny Hall
      Danny HallAug 14, 2017

      Hi Sharif

      Once the Phidget WebService goes “wonky” like that, there’s no way that I know of to get it functional again without restarting the app.

      But, you can restart the app in the middle of a roast – just double tap the home button and swipe upward on the screen, then restart Roastmaster. It will pick up right where it left of, and you’ll only have 10 seconds or so of weird data.

      I, myself, have never seen this behavior in my roasts, but others have reported it, so you’re not alone. In my own roasts, the Phidgets WebService will typically fail on the average of once every 5 roasts or so. It usually comes back on its own, but sometimes a quick restart is needed as described above.

      The folks at Phidgets are aware of the WebService problems, and have actually just rewritten all of their software from the ground up. They just released it 2 or 3 weeks ago I think. I’m working hard now trying to port Roastmaster’s code over to the new software.

      So, hopefully better days are coming for Phidgets. If development goes well, and testing does not show any bugs I plan to have that in the next release of Roastmaster.

      I’ll be testing for at least 2 weeks once I’m done coding. If you want to beta test during that time, just let me know – support@rainfroginc.com

        Ah ok got it. I was thinking if I closed the app mid roast I’d just lose out on the whole thing. That’s good to know though.

        I used to have it all hard wired, and it never had any hiccups, so I can only guess the hiccups happen when the wifi signal goes weak.

        Will keep an eye on any updates, thanks Danny.
