I’m using the hivemq cloud to publish some topics for water/gas/power consupmtion of my home.
The topics will be send by ESP8266 devices. That works well normaly.
But from time to time (4 weeks??) all topics have been deleted - only the ones that are published in this moment do create a topic.
Can anyone tell me what is happening here - I’m a bit confused.
Thanks in advance
Hi @frawall , and a warm welcome to the HiveMQ Community! We’re excited that you’re interested in MQTT and the HiveMQ broker. Your presence adds value to our community.
Topic in MQTT cannot be created or deleted. A topic only exists while there is an MQTT client subscribed to it. Please refer to MQTT Essentials lecture series to learn core MQTT concepts: MQTT Essentials - All Core Concepts explained.
To tell you what is happening here, please send a screenshot or a video of what you are observing. Elaborate on what makes you a bit confused. I am sure there is an explanation.
