I'd completely forgotten about my post here and only just read your reply! Only eighteen months or so later I've hardly roasted the past year but I have 9kg of greens to roast and I think I'll certainly have some questions along the way. Thanks.

Thanks Danny, that's very helpful. I created a test profile I could run quickly to test for the alarm and setting it to a control curve gave me the alarm sound. During the last big update of Roastmaster has something changed to the curve behaviour as I know when I've used Roastmaster in the past with the same curve I had the alert sounds? Anyway, my alerts are back.

One other thing. Changing the volume on the iPad doesn't seem to increase the sound of the alert. I find the alarm a little quiet. The alert volume seems to be set at a default level. Do you know if that can be changed?

Thanks.

Setpoint alerts are designed to tell you when control curve values change, they do not function with temperature reading curves.

Is your curve defined as a reading curve? If so, just change its type to control and you’ll get the alerts.

If you haven’t seen it, check out 18:15 on the screencast here: http://rainfroginc.com/documentation/roasting-profiles-a-comprehensive-tutorial/

This shows a pretend control curve for a Gene Cafe profile, representing the values of the roaster “heat” control. That would provide alerts in either the roast console, or the analyzer screens.

If all you want is a map of the roaster settings throughout the roast, then 1 curve is all you need, and this type of profile will suffice.

If you want to provide more detail, you can add a reading curve to that profile, that will show the approximate temperature values you observe when using that control curve on the roaster. (Shown in "Gene 1" attachment, with a preheat temp of 200)

During a roast, this would be a good way to see if the current temps displayed on the roaster are staying in line with the profile temps you have predefined, and allow you to adjust the machine based on the current temperature ramp, vs the intended temperature ramp. (Note the more detail you provide in the target reading curve, the more accurate it will be)

Going further, you could record current temps to a second reading curve (in the roast itself) to get an idea of how the current roast is behaving over time compared to your target curve in the profile. See "Gene 2" attachment. In this screenshot, the “Control Curve Plot Height” preference is set to 20% to allow screen room to easily compare the target profile temperature curve with the current actual temperature curve. The analyzer targeting mode in this screenshot is set to “Profile/Program” to  give show which curve is current and which curves are target.

In any of these examples, you’d receive alerts for the control curve values as they changes

Hope this helps
Danny

Can't wait for the videos. I've just spent the best part of a day trying to understand how to use this great looking app but I have to admit I find it quite confusing! I use a Gene Cafe. I'm sure it'll be fine once I understand all the terms; curves, profiles, programmes. Arrghh
