ESP32 Novy Controller

A WiFi-enabled controller for Novy cooking hoods using ESP32-C3-mini with 433MHz RF transmission (STX882 or FS1000A).

Overview

This project enables remote control of Novy cooking hood lights through:

• Web interface – Direct browser control
• MQTT integration – For home automation systems
• Home Assistant – Auto-discovery support via MQTT

Hardware Setup

Hardware Requirements

• ESP32-C3-mini development board (with external antenna if range is WiFi range is not enough)
• TX882 433MHz transmitter (with antenna for better range) FS1000A 433MHz transmitter
• Basic soldering equipment

Wiring

Connect the 433MHz transmitter to your ESP32:

• Data pin → GPIO 4
• VCC pin → 3.3V or GPIO 3 (directly connect VCC → 3.3V for more current)
• GND pin → GND

💡 Tip: The STX882 transmitter is a much better drop-in replacement for the FS1000A – similar price but stronger signal output.

The power control setup (GPIO 3 → HIGH) powers the transmitter only when needed, while GPIO 4 handles data transmission.

Setup Instructions

1. Clone the repository

   git clone https://github.com/renedis/ESP32_Novy_Controller.git

2. Configure your settings

   • Copy config.example.h to config.h
   • Update the configuration with your WiFi credentials and MQTT settings

3. Upload to ESP32

   • Use Arduino IDE or PlatformIO to compile and upload

Usage

Web Control

Access the web interface by navigating to your ESP32's IP address in a browser. Click the buttons to control your Novy hood.

Home Assistant Integration

Automatic Discovery (Recommended)

The controller supports MQTT auto-discovery. Once connected, all buttons will automatically appear in Home Assistant as button entities.

Note: Buttons are used instead of toggle switches because 433MHz is a one-way communication protocol.

Manual Configuration (Legacy)

HTTP Shell Commands

shell_command:
  novylight: 'curl -k "http://192.168.1.5/toggleLight"'

Manual MQTT Setup

mqtt:
  - button:
      unique_id: novy_light
      name: "NOVY-light"
      command_topic: "NOVY/button/light"
      payload_press: "ON"

Direct MQTT Control

Send payload to topic:

NOVY/button/minus/ON

3D Printed Case

A printable case is available in the repository:

Note: The case fits but could use some refinement for better fitment.

API Endpoints

Endpoint	Action
http://<ESP32_IP>/toggleLight	Toggle hood light
