Annotations
This chart displays all temperatures and state information logged by BrewPi. Not all temperatures are shown by default, but you can toggle them with the colored dots.
Click and drag left or right to zoom horizontally, click and drag up or down to zoom vertically. Double click to zoom out. When zoomed in, you can hold shift to pan around. On your phone or tablet you can just pinch to zoom.
The state information is shown as colored bars at the bottom of the graph, explanation below.
Idle
No actuator is active.
Cooling
The fridge is cooling!
Heating
The heater is heating!
Waiting to cool
The fridge is waiting to start cooling. It has to wait because BrewPi has just cooled or heated. There is a a minimum time for between cool cycles and a minimum time for switching from heating to cooling.
Waiting to heat
Idem for heating. There is a a minimum time for between heat cycles and a minimum time for switching from cooling to heating.
Cooling minimum time
There is a minimum on time for each cool cycle. When the fridge hits target but has not cooled the minimum time, it will continue cooling until the minimum time has passed.
Heating minimum time
There is a minimum on time for each heat cycle too. When the fridge hits target but has not heated the minimum time, it will continue heating until the minimum time has passed.
Waiting for peak detect
BrewPi estimates fridge temperature overshoot to be able to turn off the actuators early. To adjust the estimators, it has to detect the peaks in fridge temperature.
When BrewPi would be allowed to heat/cool by the time limits but no peak has been detected yet for previous cycle, it waits in this state for a peak.
