Greetings
I have an urgent problem. I use EMQX as a dedicated MQTT broker on a separate server with many a few services connected to it. Zigbee2MQTT, Zwave2MQTT, node-red, watermeters and so on. All of these are sending updates to EMQX and I can also se my HA instance being connected to EMQX.
No matter in which order I restart things all my MQTT sensors and devices are unavailable in HA. This seems to have happened after I upgraded HACS to 2.0, before that all was fine.
HA is version 2024.8.2.
Anyway. I removed the MQTT integration from HA and added it again. After a reboot of the different MQTT appliances I got the devices back into HA, under new names though so I have some administrative tasks ahead.
