ESP-NOW-Gateway/README.md

ESP-NOW gateway for ESP8266/ESP32

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

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.
3. Periodically transmission of system information to the MQTT broker (every 60 seconds) and availability status to the ESP-NOW network and to the MQTT broker (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. Possibility firmware update over OTA.
7. Web interface for settings.

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/gateway/70039F44BEF7").

Attention

1. ESP-NOW network name must be set same of all another ESP-NOW devices in network.
2. Upload the "data" folder (with web interface) into the filesystem before flashing.
3. WiFi router must be set on channel 1.

Tested on

1. NodeMCU 1.0 (ESP-12E Module). Unstable work.
2. AZ-Delivery ESP-32 Dev Kit C V4. Stable work.
