Manually trigger MQTT Birth Message

I am using the MQTT Transmission module and during testing we are turning the MQTT module on and off to create Birth messages, is their something I could connect to a button to for a Birth generation? I am not finding looking through the documents of what would work.

You should be able to write True to [MQTT Transmission]Transmission Control/Refresh to initiate a node/device rebirth:

Perfect! Gotta love MQTTFX…

Hi, is it possible to request a rebirth via MQTT? With some command? What is your recommendation?

Sure, just write to the Rebirth tag under Node Control beneath a given node in MQTT Engine:

I think that is only for MQTT Engine? I can not seem to find that with Transmission.

My second comment applied to MQTT Engine based on the question from @daspuru of how you can request a [remote] node to rebirth. The first example applied to MQTT Transmission and how you can have that [local] node do a rebirth.

Thanks.

@daspuru Do not get excited we are only running the Transmission module.

I have some gripe w/ MQTTfx. It hadn’t been updated in years, and has had a bug since 2018 that really gets in the way of using it with Sparkplug topics since they all start with spBv1.0. The best workaround is to start your subscription with a +/group/ when you don’t want to see all the traffic for everything.

And just now, while checking for updates, I see it’s being maintained commercially and there are no free versions any more.

So, yeah, that version with the bug is quite likely the last free version ever… :frowning:

Yeah I am surprised like someone like HiveMQ or another vendor has not made a more usable version with support outside of that commercial implementation.

It works for what it is I guess. Mosquito is super easy to deploy in docker so I could see it being super niche.
