Add support for messaging via mqtt #17148

Open normanmaurer opened 4 days ago

normanmaurer commented 4 days ago

At the moment there are various supported ways how to use messaging. It would be nice if you could add mqtt as well. This would allow to easy integrate with other software that could just subscribe to a topic.

What kind of "messaging"?

normanmaurer commented 4 days ago

This one https://docs.evcc.io/docs/reference/configuration/messaging

So I think it is not really messaging but services that is used by messaging

andig commented 4 days ago

I see. That would mean adding a custom push device. Not a priority, but happy to take a PR. Doing so it would also be nice to remove the script push device- it can already be implemented using the script plugin.

/cc @GrimmiMeloni in case you're interested

normanmaurer commented 4 days ago

Yeah for now I just use the script stuff with mosquito_pub

GrimmiMeloni commented 3 days ago

Yeah, about time for me to contribute something again. ;)

@normanmaurer what would an MVP look like? Does simply configuring a broker + a topic to publish to suffice?

normanmaurer commented 3 days ago

@GrimmiMeloni yes 🎉

andig commented 3 days ago

Spannend ist noch wie wir mit title und msg umgehen. Vllt. Lassen wir bei den custom Integrationen einfach den title weg?

normanmaurer commented 3 days ago

Or we could also use json for the payload

andig commented 3 days ago

Like it. Could be an encoding option on the custom messenger.

GrimmiMeloni commented 2 days ago

I am wondering why we are talking custom here? I was planning to just add an mqtt flavor to the list of supported messaging services (shoutr, telegram, ....)

andig commented 2 days ago

I just thought we have custom everywhere and script already is a custom integration. Why not make it fully flexible before the next user wants http?

GrimmiMeloni commented 2 days ago

OK. But if we already have a custom solution via script, then what is actually missing here? Sorry for being "stupid", but I still don't understand the actual ask. Can you maybe show an example of the configuration you expect, or some other fragment that explains what the difference between script and custom would be?
