# 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"}'`

## 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](../upload/advanced-configuration#auto-discovery) 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
