Docker

First install DockerDesktop and docker-compose:

Then you can export a path to mount as a volume and spin up the containers:

export DATA_DIR = /some/path/to/mount
docker-compose --file software/container/docker-compose.yml up

mosquitto_sub -h localhost -t '#' -p 1883
mosquitto_pub -h localhost -p 1883 -t '/' -m $(date --utc +%s)

You can login to Grafana: http://localhost:3000/login (admin:admin)

NodeRed is running here: http://localhost:1880/

We are using HelTec Automation Wirelsess Sticks ESP32 Dev-Boards. Their GitHub repo can be found here: https://github.com/HelTecAutomation/Heltec_ESP32

You can add their Board Manager to the boards managers URLs: https://github.com/HelTecAutomation/Heltec_ESP32/blob/master/library.json and find their libraries in the IDE (Sketch -> Include Library -> Manage Libraries... Search for "heltec esp32").

These boards are already V3 boards, so be careful selecting the right board and port (VCP).

Usually you can find the used port using esptool.py, but that's not working for me, atm (continue here)....

esptool.py write_flash_status --non-volatile 0

Download the firmware:

esptool.py --chip esp32s3  write_flash -z 0  ~/Desktop/GENERIC_S3-20220117-v1.18.bin
