Autoponico

Arduino

Software running on an ESP32 to report measurements taken from atlas sensors
it pushes collected measurements to an InfluxDB bucket

Get started

Install the Arduino IDE
Copy the all libraries from /libraries to your Arduino's library location, usually at ~/Documents/Arduino/libraries
cp -R ./libraries/* ~/Documents/Arduino/libraries

or create a symlink 😏 ln -fs /Users/<user>/autoponico/arduino/libraries /Users/<user>/Documents/Arduino/libraries

Open the .ino file with Arduino IDE, compile and happy upload 🔥

Note

To update from webapp, generate the .bin file from Arduino IDE, rsync it to the ws-server and send command management update from webapp, it will tell the Arduino to download that file and apply updated firmware.

WebSocket server

NodeJS program using typescript to handle websockets between webapp and Arduino boards Move to dir cd ./ws-server Install packages yarn install Run with env (cat .env | xargs) nodemon main.ts

For production, run with env (cat prod.env | xargs) ts-node main.ts

Note

sudo snap install --classic certbot sudo certbot certonly --standalone -d autoponico-ws.tucanorobotics.co

Tasmota Device Configuration

The webapp dashboard controls Tasmota devices via MQTT. Each device must be configured to connect to the ws-server MQTT broker.

Setup device

Go to https://tasmota.github.io/install/ and flash Tasmota if needed

MQTT Settings (http://<device-ip>/mq)

• Host: IP of the machine running ws-server
• Port: 1883
• Topic: Must match one of the defined device topics: fresas, valvula-tanque, luz-cannabis, main-pump
• Full Topic: %prefix%/%topic%/

Module Template (Sonoff Basic R4)

Apply via Console (http://<device-ip>/cs):

Template {"NAME":"Sonoff Basic R4","GPIO":[0,0,0,0,224,0,544,0,0,32,0,0,0,0,0,0,0,0,0,0,0,0],"FLAG":0,"BASE":1}
Module 0

GPIO mapping: GPIO4 = Relay1, GPIO6 = LED1, GPIO9 = Button1.
