Hi Tim

I was certain I had tried to contact them in the past, but can't find any record of it.

Now that Roastmaster has its own internal Bluetooth protocol and engine, adding support for data logging should be a trivial matter if it supports Bluetooth LE, and the manufacturer is willing to allow it.

You don't by chance have an email contact for them do you. If not, I'll find one and reach out to them.

I will be evaluating this soon for possible inclusion in a future release of Roastmaster based on the manufacturer spec's. They appear to be better than standard thermistor probes, at first glance, but I'm getting more information from the manufacturer.

Yep. Delta curves are always graphed in the same color as the main part of the curve. Whether or not the Delta representation is shown is controlled in Preferences, as I outline earlier. Yours is set to on...you can see the delta curve on the screenshot you posted. I've annotated it with labels (attached).

Just to make the distinction...the blue curve in your screenshot is a control curve. These graph as stair-steps in their own section of the Analyzer, and are meant to correspond to machine control settings, e.g. gas flow, electric current, damper and fan settings, etc. The green curve is a reading curve - these represent (at the moment) just temperature readings. Reading curves can show a Delta (Rate of Rise) curve, while Control curves cannot.

In the Roasting with Roastmaster screencast 5, I've got two Reading curves bound to probes. The green Bean Temp curve, of course, is self-explanatory. The blue curve, though, is a probe in the exhaust vent. That serves as an indicator in my profiles of how I usually work the damper at certain points of a roast. The same things could be achieved with a Control curve, similar to the blue curve in your screenshot - wherein I'd input nodes whenever I change the damper setting. Kind of two different ways in this particular example to accomplish the same thing. I like hands-off roasting, so I don't work with control curves myself.

But, to illustrate how the main curve and its corresponding Delta (Rate of Rise) curve work together, the top green curve in the video is the actual Reading curve consisting of temps - a series of nodes that are read by the probe. The very bottom green curve that's more squiggly is its corresponding Delta (Rate of Rise) curve. It simply shows a graphical and relative value of how quickly the main Reading curve is rising at each point in the roast.

The more data points the curve has, the smoother they both will be. Programatically, I cannot accurately employ any type of graphical curve-smoothing for Reading curves in cases of manual data entry, because that would be guesswork on my part as to how faithful the user is in entering nodes. So, they remain linear from node to node (notice how your green curve looks more like a dot-to-dot drawing). When you get your probes set up, you'll see them smooth out. I'd personally advise shielded (ungrounded) probes - they provide the smoothest transitions in curves. But, either style would word.

In the current version of Roastmaster, you cannot bind a probe to a control curve. That will change soon - lots of expansions are coming in the arena of profiling and data logging. Until then, though, Control curves (the stair-stepped curves) are limited to manual data entry.

Hi

Very glad to hear you're enjoying Roastmaster!!

Sure - this is easy to do and is accomplished via "Profiles". Profiles can contain Reference Curves consisting of curves with past data that you want to match in a future roast, alongside Curve Templates, which are templates Roastmaster will use to create new data curves that can log data in future roasts.

It sounds like all you want at the moment is a set of Curve Templates, but you can also incorporate one or more Reference Curves as a visual guide in your profiles.

Once a profile is configured, all you have to do is choose it when starting a roast, and the roast will be automatically configured, both with the Reference curves for targeting, and new Data Curves for data collection.

I walk through the process in the Roasting with Roastmaster Part 2 screencast. Essentially, you just choose "Create Profile from this Roast" to handle the creation automatically. You could optionally create a profile manually and copy and paste specific reference curves from any prior roast if you want to as well.

Let me know if you any other questions.

You can manage profile lists by navigating to the roaster in question, then tapping "Profiles" in that details screen. Tap the edit button at the top to put the table into edit mode, and select the profile(s) you want to delete. Then tap the red X at the bottom.

Let me know if you have any issues.

Hi Larry.

Roastmaster is compatible with any iOS device running iOS 9.3.5 to 11.

For automated data logging, you'd need the ThermaQ Blue, or another supported hardware device.

The ThermaQ Blue is by far the easiest to use and configure. Any other questions let me know.
