This feature has been requested a lot and I've always thought it was a great idea. The concept is that as your meat approaches doneness, the pit temperature will ramp down slowly so that when the meat is done, the pit is at the same temperature as the meat and therefore can "hold" indefinitely without overcooking. We'll have to see in practice how that works which is where you HeateMeterers come in.
New on the Alarms page is a section called Ramp Mode where you enter which probe to track, when to start ramp mode, and where to end it.
In practice it looks like this. When the "watched" probe temperature passes the "trigger temperature", the setpoint is proportionally lowered from the original setpoint down toward the "target temperature". Here, the trigger temperature is 180 and the target is 200. There's also an indicator on the home page that shows that ramp mode is active, with the start setpoint and the target temperature. The color can be changed by overriding the CSS class "ramp".
Ramp mode does persist across reboots! So if your ramp ins't complete and you pull the plug, it will still be in ramp mode when you plug it back in next week. The easy way to disable ramp mode is to set a setpoint so I don't think this will be a problem and guarantees that the ramp mode isn't reset by a momentary power glitch. Ramp mode automatically ends when the watch temperature is within 1 degree of the target. Also, the ramp setpoint is only updated once per minute, because writing a new setpoint every second just wastes EEPROM writes.
A big question on my mind is if this will actually work. If you ramp down the temperature, there's a chance that the food will never reach the target temperature, or that it will reach the target temperature somewhere in 2018. When I tried to test it yesterday ramping 180->200 = 225->200, I got about to 190 food / 212 setpoint before I had to pull it and stick it in the oven because I was running out of time. I'm interested to see what works for everyone else. Maybe 190 ramp trigger would be a better start?
Finally, "Ramp Mode" is pretty boring sounding so I might jazz it up with a trademarkable name.

The feature is available in the snapshot firmware but only the linkmeter package should be needed if you're already on a snapshot.
