Plynx dashboard for a single board: a light switch, a temperature gauge and a humidity display

Drag a widget. Bind it to a pin. Your hardware does the rest.

How it works

Fifteen minutes, soldering included

The dashboard should not take longer than the project itself.

Create a project in the app

Drag widgets onto the canvas and bind each one to a pin. Buttons drive outputs, gauges and charts read sensors.

Flash this on your board

The classic device library plus the token the app gives you. Nothing else to configure.

greenhouse.ino

#define PLYNX_PRINT Serial
#include <WiFi.h>
#include <PlynxSimpleEsp32.h>

char auth[] = "YOUR_AUTH_TOKEN";
char ssid[] = "YOUR_WIFI";
char pass[] = "YOUR_WIFI_PASSWORD";

void setup() {
  Serial.begin(115200);
  Plynx.begin(auth, ssid, pass);
}

void loop() {
  Plynx.run();
}

Done. They are talking

Values stream in live, taps and slides reach your pins instantly. Full walkthrough in the docs.

Widgets

Over 20 widgets, each one configurable

Buttons, sliders, gauges, charts, joystick, RGB picker, LCD, terminal, level indicators, timers and more. Pick the pin, the range, the refresh rate, the color. Themes that look good in light and dark.

Privacy

Your data, your server

Plynx talks directly to a small open source server you can host on any Raspberry Pi. No cloud account with us, no telemetry, nothing in the middle. Not into self-hosting? A free public instance is available too.
