 # 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

 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).
+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. 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.
- ```
-
+6. Possibility firmware update over OTA.
+7. Web interface for settings.
+  
 ## 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.
+4. 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.
+1. NodeMCU 1.0 (ESP-12E Module). ESP-NOW + WiFi mode. Unstable work.

 ## To Do

 - [X] Automatically add ESP-NOW devices configurations to Home Assistan via MQTT discovery.
- [X] LAN connection support.
- [X] nRF24 device support (via [RF Gateway](https://github.com/aZholtikov/RF-Gateway)).
- [ ] BLE device support (via BLE Gateway).
- [ ] LoRa device support (via LoRa Gateway).
-
-Any feedback via [e-mail](mailto:github@zh.com.ru) would be appreciated. Or... [Buy me a coffee](https://paypal.me/aZholtikov).
+- [ ] LAN connection support.
+- [ ] nRF24 device support (in current time uses "RF Gateway").
+- [ ] BLE device support (for ESP32).
