IoT Platform

Docker

First install DockerDesktop and docker-compose:

• https://www.docker.com/products/docker-desktop/
• https://docs.docker.com/compose/install/

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

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

Grafana

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

NodeRed

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

Hardware

Arduino IDE

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

I had to install VCP Drivers, first: https://www.silabs.com/developers/usb-to-uart-bridge-vcp-drivers?tab=downloads

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").

Find the port

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
