HiveMQ learning (How to publish?)

Configuration
1

Attempting to add MQTT to my HA. I have added a ESP8266 and I can see the updates from the device running OpenMQTTGateway.

I want to publish to the device from the HiveMQ panel but I am not clear how?

for Topic I enter

home/OpenMQTTGateway/commands/MQTTtoIR

and for message to OMG I put

-m '{"value":551489775}'

No flashing led or indication that the message is received?

Thanks for any insight!

I don’t know HiveMq, but since this is the HA forum. Your topic seems correct, in HA go to developer tools -> MQTT, enter home/OpenMQTTGateway/commands/MQTTtoIR under topic and 551489775 as payload. Then click publish.

Does this error mean something? I guess it would indicate that I can’t get messages back?

How do I fix this issue?

Logs below…

Using the ardunio IDE I see some transmissions

This indicated OpenMQTTGateway received 551489775, but it does not show where it is coming from.

This seems to indicate that hassio is unable to connect to your mqtt broker. How did you configure hassio ?
