Hi all,
To address a soon coming broker (over-)load issue, we are changing our single instance of the Mosquitto broker on mqtt.victronenergy.com to a cluster of Mosquitto brokers.
The first step is that we've made a series of new dns records (mqtt123.victronenergy.com). And in Venus OS v2.40 we've added a change that it connects to one of those addresses.
For now, they all still point to the same single Mosquitto instance as before, so technically nothing has changed.
But, in the coming weeks, we'll be deploying the new cluster. And from that moment onwards, any customer code that connects to mqtt.victronenergy.com will need to have to be adapted to the new scheme. See the changes in the dbus-mqtt readme for what has changed and what you need to do in case you are using this in your software projects.
In the interim, customers can keep using the previous Venus OS version, v2.33 is the latest one. It will keep using mqtt.victronenergy.com, and we'll keep that up and running for a long time to come.
More technical background about this change can be found in the related Venus OS issue:
