mosquitto_pub -h 192.168.178.36 -p 1884 -u myusername -P mypass -t “home/OpenMQTTGateway/commands/MQTTtoSYS/config” -m ‘{“ohdiscovery”:true}’

You need to replace OpenMQTTGateway by the name of your gateway, here OMG_ESP32_BLE

mosquitto_pub -h 192.168.178.36 -p 1884 -u myusername -P mypass -t “home/OMG_ESP32_BLE/commands/MQTTtoSYS/config” -m ‘{“ohdiscovery”:true}’

wrong copy paste :slight_smile:
i change the command but still the same. even after reboot the gateway its still false

64

Did you try with MQTT explorer ? Also note the quote that should be used below
{"ohdiscovery":true}

Hi,

Try maybe to publish the command with a retain flag so that it is taken at start

Hi,

I fix it, but just compiled and flash it again with the openhab option true in the environment file.
It discovered the new things and become green in seconds.

Thanks for your support

Hello,

Do you mean that using the build flag worked right away?

72

Hi,
Yes exactly.
With the ready firmware even if the flag was changed with the command, i could not make them work because the “| is_defined” was always there.

Thanks

Hello,

I have added a save option to the command in this Pull Request:

Could you try it and let me know if it works ?
mosquitto_pub -t "home/OpenMQTTGateway/commands/MQTTtoSYS/config" -m '{"ohdiscovery":true, "save":true}'

Sorry for the late reply.

Thanks
