Hello, I am trying to use a simple MQTT server to pass data from a remote IOT setup to my home. I am using a Soracom SIM as the internet connection.
I send the data to Soracom via MQTT and it transfers the data to my HiveMQ MQTT account where I access and use at home. This is a raspberry pi with Node Red sending the data.
This all works provided that I send the data every 5 mins. If I change this to 10 mins, the Hive servers generates a send error, which I presume is a Time Out problem.
I have a workaround where I send a “msg.payload=true” every 5 minutes, and that seems to keep the connection alive.
Is there a better method? I would prefer to reduce the data flow as I have a 25Mb per month limit with Soracom.
Thanks
