Fermentation Steps not start
Hello, I use the actual stable release 3.0 of CBi and have the following Problem: When I define different steps of fermentation with different temperatures the step-timer didn't start when the temperature is reached. E.g. the temperature of the step is 18°C, the fermenter head to 18,5, in the brewing step now the timer starts, but in the fermentation it didn't start. I tstarts only when the temperature exactly is 18°C, what is not really happens. Any idea what the problem can be? Hardware? Settings? Software?
If the steps set point is 18 and the temp is 18.5 the fermeter will try to cool in order to reach 18 before starting the timer. The kettles only heat, so anything above the set point is assumed step done.

The problem is the settling in the scheme, this can take too long and the sensor always returns promptly. Thus, I had maybe 18 ° C but the sensor is read again at 17.95 ° C and thus does not start the step
The sensors are read every few seconds ( 15 on my setup, 5 by default ), even with 12 bit resolution on a 40L fermenter the temp don't move so fast to miss the right temp. I could agree that considering an epsilon error ( |actual_temp - target_temp| < eps ) is more correct, and you set up the epsilon value to the fraction of degree you want.

The epsilon is no an option now. A modified Fermenter logic can be added. Depending on the type of sensor you used you can adjust the refresh time. AdvancedOneWire add on allows that.

Where can I set the epsilon value or the time value?

Hi, I have the following issue: Target: 18º Real temp: 18.5º
Step 1 ---- 19º 5 minutes Step 2 ---- 14º 5 minutes Step 3 ---- 21º 5 minutes
(performing a test)
I start but never move to the next step or control the temperature by activating any output!
How are the fermentation steps used?
Thanks in advance.
You need to set the fermenter in Auto & start de steps
