Web flasher

Install PlantHub on your ESP32 without leaving the browser.

Pick your hardware kit, check the wiring, click Connect & flash. Firmware uploads in about 30 seconds. No drivers, no Arduino IDE, no command-line tools — just a USB cable and Chrome (or Edge, Brave, Opera).

1. Pick your hardware kit

Match the chip and sensor combo on your board. Each preset includes a wiring diagram. Don't see your exact board? Try the closest preset — most ESP32 dev boards are interchangeable for our purposes.

Want to read the code first?

All firmware is open source. Audit it, fork it, customize sensors and actuators with the template system, or read the MQTT topic structure before you flash.
