3. BrewPi Controller Configuration¶
Once your BrewPi controller is set up within Fermentrack it’s ready for configuration. If you’ve already configured your controller on either another installation of Fermentrack or an installation of brewpi-www, then you may already be ready to go. Otherwise, just follow these instructions to get on your way.
- Go to your Fermentrack installation’s main page, and click “View Dashboard” underneath the device you wish to configure.
- From the menu at the top with your device’s name, choose “Configure Sensors/Pins/Devices”
- A screen will appear showing you the configuration status of your device. At a minimum, you need to have a heating pin, cooling pin, and chamber sensor set for your device to operate.
- Configure each of the devices listed under “Available Devices” - so long as
3.1. Heating/Cooling/Door Sensor Pin¶
Heating/cooling are configured by pin number. In most cases the correct pin will be prescribed, with the function listed out in the name. (On ESP8266 devices, for example, you will see a header similar to “Pin 16 ( D0 (Heat))”. This is generally the “heat” pin.)
To configure, simply choose the device function from the drop down menu (Heating Relay, Cooling Relay, etc.), set whether or not your relay requires the pin to be inverted (for most mechanical relays, you want Invert Pin to be “Inverted”) and click “Assign”
While the door sensor pin will generally appear as available to configure, you should not set this pin unless you have an actual door sensor connected to your controller. If you set this up incorrectly your controller may think the door to your fermentation chamber is always open, and fail to trigger heating/cooling as expected.
3.2. Temperature Sensors¶
OneWire temperature sensors are configured by device address rather than the pin they are connected to. Connect your OneWire sensors to your BrewPi controller, wait a few seconds, and refresh the page. You should see all connected sensors listed under either Available Devices or Installed Devices.
To install an available temperature sensor, simply choose the device function (Chamber Temp, Room Temp, Beer Temp, etc.) and click “Assign”. Your BrewPi controller will configure the device appropriately.
3.3. Other Options (Chamber fan, chamber light, etc.)¶
While the BrewPi controller firmware allows for other options to be selected such as chamber fan, chamber light, etc. these options don’t actually do anything and should be ignored.
