System commands (ESP only)

Restart the ESP

mosquitto_pub -t "home/OpenMQTTGateway/commands/MQTTtoSYS/config" -m '{"cmd":"restart"}'

::: tip With Home Assistant, this command is directly avalaible through MQTT auto discovery as a switch into the HASS OpenMQTTGateway device entities list. :::

Erase the ESP settings

mosquitto_pub -t "home/OpenMQTTGateway/commands/MQTTtoSYS/config" -m '{"cmd":"erase"}'

::: tip With Home Assistant, this command is directly avalaible through MQTT auto discovery as a switch into the HASS OpenMQTTGateway device entities list. :::

Retrieve current status of the ESP

mosquitto_pub -t "home/OpenMQTTGateway/commands/MQTTtoSYS/config" -m '{"cmd":"status"}'

Auto discovery

You can deactivate the MQTT auto discovery function, this function enable to create automaticaly devices/entities with Home Assistant convention.

Deactivate

mosquitto_pub -t "home/OpenMQTTGateway/commands/MQTTtoSYS/config" -m '{"discovery":false}'

Activate

mosquitto_pub -t "home/OpenMQTTGateway/commands/MQTTtoSYS/config" -m '{"discovery":true}'

If you want the settings to be kept upon gateway restart, you can publish the command with the retain flag.

::: tip Auto discovery is enable by default on release binaries, on platformio (except for UNO). With Arduino IDE please read the advanced configuration section of the documentation. :::

State LED usage

The gateway can support up to 3 LED to display its operating state:

• LED_INFO switched ON when network and MQTT connection are OK 5s ON, 5s OFF when WIFI is disconnected 1s ON, 4s OFF when MQTT is disconnected

• LED_RECEIVE Blink for TimeLedON 1s when the gateway receive a signal from one of its module so as to send to MQTT

• LED_SEND Blink for TimeLedON 1s when the gateway send a signal with one of its module from an MQTT command
