# CraftBeerPi4 Kettle Logic for PID Auto Tune
- Initial Version which is based on the CraftbeerPi3 Plugin from IndyJoeA (https://github.com/IndyJoeA/cbpi_PIDAutoTune)
- The purpose of this plugin is to autotune your System and determine automatically P, I and D values to optimize the heating for your system.
- The derived values have to be entered later in your PID Kettle Logic.
- For more info on PID and autotuning, you can check out the following articles:
- (https://github.com/Manuel83/craftbeerpi/wiki/Autotune-PID)
- (https://github.com/Manuel83/craftbeerpi/wiki/Manual-PID-adjustment)
- Installation:
You can install it directly via pypi.org:
- sudo pip3 install cbpi4-PID-AutoTune
Alternativeley you can install (or clone) it from the GIT Repo. In case of updates, you will find them here first:
- sudo pip3 install https://github.com/avollkopf/cbpi4-PID_AutoTune/archive/main.zip
- Parameters:
- Output Step: Defines the output power in % used for steps to ramp up to a temperature. Default is 100%.
- Max Outpuz: Defines the maximum outpout power in % you are using with your system. Default is 100%.
- Lockback Seconds: Defines the time in seconds how far the routine is locking back to identify temperature peaks. 30 seconds is typical. If you experience issues, increase the time (e.g. 60 seconds)
- Hardware Setup:
- After installation go to hardware settings
- Select PIDAutoTune as Kettle logic.
- Select the Heater, Agitator and Sensor for your Kettle
- Enter the parameters with the default values or change them to your needs as shown in the image below.
- Usage:
- Go tou your cbpi4 dashboard and add a Kettle and KettleLogic.
- You should run the Autotune as realistic as possible.
- Therefore you should at least use the typical amount of water you are using also for a mash
- Set a Kettle temperature via the Kettle Logic. I selected for instance 67C which is somehow between the typical mash temps of 62C and 73C
- In my case I added even malt which is easy with the braumeister malt pipe as I just added the pipe back into the kettle after a full brewing step and was using the same amount of water
- Start the automatic Kettle Logic (Click on the car symbol) and have a beer as it'll take sme thime. The system will heat up to the setpoint and overshoots intentionally.
- If you are having a pump in your system or other agitators that may impact the heating cycle, you should run them also during the Autotune process
- It is waiting until the temp is going down 0.5C below the target value.
- Then it is repeating this procedure several times.
- While running, it is writing a log file into the logs directory -> autotune.log
- If successfull, the P, I and D values are listed in the log file and a message is displayed in the dashboard.
- You can copy this message and enter the values then afterwards into your real Kettle Logic you are using for the mashing.
