 2. ESP-NOW mesh network based on the [zh_network](https://github.com/aZholtikov/zh_network).
 3. For initial settings use "menuconfig -> ZH ESP-NOW Switch Configuration". After first boot all settings will be stored in NVS memory for prevente change during OTA firmware update.
 4. To restart the switch, send the "restart" command to the root topic of the switch (example - "homeassistant/espnow_switch/24-62-AB-F9-1F-A8").
-5. To update the switch firmware, send the "update" command to the root topic of the switch (example - "homeassistant/espnow_switch/70-03-9F-44-BE-F7"). The update path should be like as "https://your_server/zh_espnow_switch_esp32.bin" (for ESP32) or "https://your_server/zh_espnow_switch_esp8266.app1.bin + https://your_server/zh_espnow_switch_esp8266.app2.bin" (for ESP8266). The time and success of the update depends on the load on WiFi channel 1. Average update time is up to five minutes. The online status of the update will be displayed in the root switch topic.

Average update time is up to some minutes. The online status of the update will be displayed in the root switch topic.
 6. To change initial settings of the switch (except work mode), send the X1,X2,X3,X4,X5,X6,X7,X8,X9,X10 command to the hardware topic of the switch (example - "homeassistant/espnow_switch/70-03-9F-44-BE-F7/hardware"). The configuration will only be accepted if it does not cause errors. The current configuration status is displayed in the configuration topic of the switch (example - "homeassistant/espnow_switch/70-03-9F-44-BE-F7/config").
 
 MQTT configuration message should filled according to the template "X1,X2,X3,X4,X5,X6,X7,X8,X9,X10". Where:
