# ESP-NOW gateway for ESP8266/ESP32 # ESP-NOW gateway for ESP8266/ESP32
Gateway for data exchange between ESP-NOW devices and MQTT broker via WiFi/LAN. Gateway for data exchange between ESP-NOW devices and MQTT broker via WiFi.
## Features ## Features
1. Creates an access point named "ESP-NOW gateway XXXXXXXXXXXX" with password "12345678" (IP 192.168.4.1). 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). 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), 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). 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. 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. 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. 6. Possibility firmware update over OTA.
7. Possibility firmware update over OTA (at ESP_NOW_LAN mode via access point only). 7. Web interface for settings.
8. Web interface for settings (at ESP_NOW_LAN mode via access point only).
9. 3 operating modes:
```text
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 ## Notes
1. ESP-NOW mesh network based on the library [ZHNetwork](https://github.com/aZholtikov/ZHNetwork). 1. ESP-NOW mesh network based on the library [ZHNetwork](https://github.com/aZholtikov/ZHNetwork).
2. Regardless of the status of connections to WiFi or MQTT the device perform ESP-NOW node function. 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"). 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:

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