# 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:
|
|
|
|
```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
|
|
|
|
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.
|
|
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:
|
|
|
|
```text
|
|
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.
|
|
|
|
