 # ESP-NOW gateway for ESP8266/ESP32
 
-Gateway for data exchange between ESP-NOW devices and MQTT broker via WiFi.
+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.
+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) and availability status to the ESP-NOW network and to the MQTT broker (every 10 seconds).
+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. Possibility firmware update over OTA.
+6. Possibility firmware update over OTA (at ESP_NOW_LAN mode via access point only).
-7. Web interface for settings.
+7. Web interface for settings (at ESP_NOW_LAN mode via access point only).
+8. 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. WiFi router must be set on channel 1.
+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.
