wittch-sense

A KNX bus sensor module based on the Adafruit Qt Py.

• provide up to 4 1bit comm objects for Reed sensors
• each sensor should be configurable through ETS
• parameter to enable active sending of sensor state every x seconds
• add programming button
• use neo pixel to indicate system state (configured, programming mode, ...) if there is enough current available from the KNX bus
• a way to disable power from KNX bus when USB is connected, or the other way around
• add PCB with level switcher for UART (Qt Py 3.3 <-> KNX bus 5.0)

Hacking

If nix is installed and direnv for this directory is enabled (direnv allow) you'll be dropped into a nix shell with platformio and it will install the core and library dependencies. So you should be able to simply compile and run the project with:

pio run
pio run --target upload

Once after cloning and after adding dependencies reinitializing the project is required to create the lsp config (for ccls):

pio init --ide emacs --board adafruit_qt_py_m0
