Attached below is the profile I "migrated" while developing the events feature. I converted it from an existing profile containing control curves, and honed it for couple of months to work well with both the first batch where the roaster is a bit cooler, and subsequent back-to-back batches where its fully heated.
For auto-trigger alerts, and event can be set to either before, during or after the roast. In my profile, I have an event "Roaster Charged", set to alert before the roast, to let me know when my charge temp has been reached. The rest are set to fire during the roast.
As you work with events, you'll notice in a event details screen, an event can be one of three things:
- Marker: this is the "general" type - a simple text string that can be anything you want
- Turnaround: when set to auto-trigger, will fire as soon as the temp starts to rise, after 15 seconds of roasting (giving probes time to equalize)
- Drying End: Signifies the end of the drying phase - can be set to auto trigger at a specific temp
The reason for the significance is that the latter two (turnaround and drying) are integrated into the reporting metrics. (Ramp and development are inferred from crack times). So, with events, it will be possible to run reports and compare turnaround time, vs duration, or maybe drying percentage vs. development percentage. This is the means by which Roastmaster knows which is which.
I encourage you to experiment with reporting, if you haven't yet. The enhanced reporting metrics are really quite an eye-opener for finding patterns in roasts. Plus, I gave all the reports the ability to find relevant cupping scores in addition to the two metrics you choose. So, in the line chart graph, tap the bottom left button, and you can see cupping scores overlaid on the two metrics you chose.
Let me know if you have any questions - I think the first help file I do for the site will deal with events.
PS: My go-to roaster is an electric 1kg Dahlian. Great roaster, but, being electric, not as responsive as a gas roaster. So, I run heat at 100%, and just jockey the damper. At my "Open Damper" alert, I open the damper to full, and leave for roughly 15 seconds, letting smoke and chaff clear. Then I close to anywhere between .5 and 1 (barely open). This lets me coast into first crack gently, and extend development time. Then, another event reminds me to close it at the time that will let the heat build back up for my target drop time.
This profile is very heavy on dev time. The coffee drinkers in my family are split between drip and espresso, so I love getting ahold of some heartier centrals, or other beans normally too bright for SO espresso, and muting them down for some really lively, but not over-the-top espresso.
