cbpi4-PIDBoil 0.0.7

CraftBeerPi4 PID Kettle Control Plugin

Craftbeerpi4 Kettle Logic Plugin

PID Logic with boil threshold.

If the target Temperature is above a configurable threshold the PID will be ignored and heater is switched on to the max output value. This is helpful if you use the same kettle for mashing and boiling.

Once the boil threshold temperature is reached, the boil will be done with the max boil output power

Installation:

You can install it directly via pypi.org:

• sudo pip3 install cbpi4-PIDBoil

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-PIDBoil/archive/main.zip

Afterwards you will need to activate the plugin:

• cbpi add cbpi4-PIDBoil

• cbpi >= 4.0.0.45 from my fork is required. The setup will check, if this repo is installed

Parameters

• P - proportional value
• I - integral value
• D - derivative value
• SampleTime - 2 or 5 seconds -> how often the logic calculates the power setting
• max output - heater power which is set above boil threshold
• Boil Threshold - Above this temperature the heater will be set to Max Boil Output Power (default: 98°C / 208F)
• Max Boil Output - Power (%) that is used above Boil Threshold Temperature (default: 100%)
