Birth telegram comes always

[mjan-pxcd]

Hello,

it seems that a birth message is always sent even if the option "bith message immediately" is unchecked.

Is this the way it is supposed to be?

Output Birth Topic by first connection:

{
  "timestamp" : 1682065348698,
  "metrics" : [ ],
  "seq" : 0
}

It would be optimal if no bith massage comes when the option is unchecked, so that no "wrong" birth message is on the mqtt broker to start with.

What is the topic on the birth message NBIRTH or DBIRTH? Also, did you remove the metrics? or do you have a device with 0 metrics?

hi,

its the birth topic, one device with no metrics, send immediately false:

{
  "timestamp" : 1682331804692,
  "metrics" : [ ],
  "seq" : 1
}

device with metrics. immediately false --> no birth topic:

device with metrics. immediately true:

{
  "timestamp" : 1682332052978,
  "metrics" : [ {
    "name" : "test",
    "dataType" : "Int32"
  }, {
    "name" : "test2",
    "dataType" : "Double"
  } ],
  "seq" : 1
}

The idea was to send my own DBirth topic to add more meta data to it. That works also so far, I have then only always 2 times dbirth with 0 and my own

addendum: the zero only occurs when i manually trigger dbirth, if I let dbirth write to the device automatically after e.g. 0,1s everything works correctly.

So the problem you are seeing is that a Device with 0 metrics will send birth immediately?

What difference does the 0.1s make?
