[Feature Request]: Root topic by channel or similar solution … about firmware HOT 5 CLOSED

They have to break down into smaller groups, that is what the topic is there to do.

The c is old firmware and was a mistake, it has a very short remaining shelf life people on c will need to upgrade their firmware to continue to use the public channel on the public mqtt server.

Unfortunately, that's not how it works in reality. As soon as different root topic are set, cross-communicating with users of a different setting is no longer possible.

It would be nice if two regions could continue to communicate with each other, to warn of dangers such as flooding and the like, regardless of frequency.

Unfortunately, it doesn't look like that at the moment. If region A has decided to continue using "msh" as the root topic, but the neighboring region has decided to use msh/EU_868 or msh/EU_433, then communication is no longer possible. That's probably the situation in Germany at the moment.

The update from c to e is of course logical and inevitable.

If setting the root topicps via channel is not possible, then perhaps msh/EU or something similar would be a possible overarching solution.

It is just a string, so you can use whatever string you want, the goal of the presets is to get away from flooded global topics.
