Project created in course of the "Girls‘Day – Mädchen-Zukunftstag"
https://www.bafza.de/engagement-und-aktionen/girlsday-und-boysday
Project goals was to setup a device which will be used to set a timer to shut down lights in the dormitory.
- somewhat "triggerable" light-switch (in our case: KNX based lighting with a KNX-IP-Tunnel-Interface "controlled" by node-red)
- esp32
- sh1106-display or ssd1306-display
- rotary encoder KY-044
- wiring / breadboard / soldering iron. We ended up wrap-wiring the connections because it was safer and the day was over quite fast.
- not needed, but somewhat "good": printed 3d-case. We ended up using this one and just physically enlarging the hole with a step drill to make enough room for the KY-044 rotary encoder.
- rotary-encoder
- wifi
- installed mqtt-server (we used a local mosquitto instance for that purpose)
- installed node-red (used to bridge mqtt to knx) so that we can just send a mqtt-msg and node-red sends the appropriate knx-datagram to shut down the light
- not needed, but we were quite happy to use thonny for copying over files and reworking some parts of the code
- install a fresh version of micropython on an esp32 with wifi capabilities
- copy over all files found in this repo to the device
- either adapt esp32config.json or create a copy of esp32config.json named as esp32config.local.json and adapt settings therein such as:
- wifi-networks credentials
- mqtt-broker credentials
- enable i2c and set pins appropriately
- enable rotary and set pins appropriately
- create logic (e.g. via node-red) which listens to the "lightswitchfeed"-topic on the mqtt-broker and if data comes in triggers the light accordingly
- since the code is placed in boot.py and main.py just booting/resetting the esp32 should make this work

which has then to be renamed to .mp4 since it would not "play" otherwise ?! Giving up on video-embed in this file now...
