esp-now-gateway's Introduction

ESP-NOW gateway for ESP8266/ESP32

Gateway for data exchange between ESP-NOW devices and MQTT broker via WiFi/LAN.

Features

  1. Creates an access point named "ESP-NOW gateway XXXXXXXXXXXX" with password "12345678" (IP 192.168.4.1).
  2. Possibility a device search through the Windows Network Environment via SSDP (at ESP_NOW_WIFI mode).
  3. Periodically transmission of system information to the MQTT broker (every 60 seconds), availability status to the ESP-NOW network and to the MQTT broker (every 10 seconds) and current date and time to the ESP-NOW network (every 10 seconds).
  4. Automatically adds gateway configuration to Home Assistan via MQTT discovery as a binary_sensor.
  5. Automatically adds supported ESP-NOW devices configurations to Home Assistan via MQTT discovery.
  6. Automatically adds supported nRF24 devices configurations to Home Assistan via MQTT discovery.
  7. Possibility firmware update over OTA (at ESP_NOW_LAN mode via access point only).
  8. Web interface for settings (at ESP_NOW_LAN mode via access point only).
  9. 3 operating modes:
ESP_NOW       ESP-NOW node only. Default mode after flashing.
ESP_NOW_WIFI  Gateway between ESP-NOW devices and MQTT broker via WiFi.
ESP_NOW_LAN   Gateway between ESP-NOW devices and MQTT broker via Ethernet. Preferred mode.

Notes

  1. ESP-NOW mesh network based on the library ZHNetwork.
  2. Regardless of the status of connections to WiFi or MQTT the device perform ESP-NOW node function.
  3. For restart the device (without using the Web interface and only if MQTT connection established) send an "restart" command to the device's root topic (example - "homeassistant/espnow_gateway/70039F44BEF7").
  4. W5500 connection:
ESP8266 (GPIO05 - CS, GPIO14 - SCK, GPIO12 - MISO, GPIO13 - MOSI).
ESP32   (GPIO05 - CS, GPIO18 - SCK, GPIO19 - MISO, GPIO23 - MOSI).

Attention

  1. ESP-NOW network name must be set same of all another ESP-NOW devices in network.
  2. If encryption is used, the key must be set same of all another ESP-NOW devices in network.
  3. Upload the "data" folder (with web interface) into the filesystem before flashing.
  4. At ESP_NOW_WIFI mode WiFi router must be set on channel 1.

Tested on

  1. NodeMCU 1.0 (ESP-12E Module). ESP_NOW_WIFI mode. Unstable work.
  2. AZ-Delivery ESP-32 Dev Kit C V4. ESP_NOW_WIFI mode. Stable work.
  3. NodeMCU 1.0 (ESP-12E Module) + W5500. ESP_NOW_LAN mode. Stable work.
  4. AZ-Delivery ESP-32 Dev Kit C V4 + W5500. ESP_NOW_LAN mode. Stable work.

Supported devices

  1. RF Gateway
  2. ESP-NOW Switch
  3. ESP-NOW Light/Led Strip
  4. ESP-NOW Window/Door Sensor
  5. ESP-NOW Water Leakage Sensor

To Do

  • Automatically add ESP-NOW devices configurations to Home Assistan via MQTT discovery.
  • LAN connection support.
  • nRF24 device support (via RF Gateway).
  • BLE device support (via BLE Gateway).
  • LoRa device support (via LoRa Gateway).

Any feedback via e-mail would be appreciated. Or... Buy me a coffee.

esp-now-gateway's Issues

Adding encryption?

Hello,
This is not an issue but feature request.

I have been following your "ZHNetwork" since last month. its been great to see and follow along with the development. I have one basic question regarding esp-now communication protocol, do you intend to add encryption to the communication in future?

Best regards,
Chandan
