Display
This firmware supports Nextion Touchdisplay HMI TFT 3.5" NX4832T035 (basic series), NX4832K035 (enhanced series) an NX4832F035 (discovery series). Three pages are availible:
Mode BrewPage: max 4 CBPi kettles overview
Mode KettlePage: current and target temperature
Attention: you must enter sensors IDs from CraftbeerPi4 in the sensor configuration page. Otherwise displayed tempertures may be wrong or mixed up between different sensors.
InductionPage: manual induction hob controller
BrewPage is usefull while brewing. When your mash process completed the use of BrewPage (overview) ends. The Kettlepage can be used any time as a kettle temperature information pannel. The induction mode can be usefull beside automated brew. Instead the InductionPage offers manual control of your induction cooker. The display can be configured via the WebIf. While display is activated, GPIO D1 (SDL) and D2 (SDA) are in use (software serial tx/rx).
