Event Signals

[ZRays51]

Hello. A question about event signals.
When I modify attributes of a thing via HTTP API or Ditto UI, I get event signals via MQTT connection. But when I modify thing attributes with MQTT message, I do not get any signals. Is this normal or is there perhaps something wrong with my configurations?

Hi @ZRays51
You would not get an event in the same MQTT connection which caused the event - that way you can e.g. prevent loops which originate "from one source".
You can however create a second MQTT connection, subscribing for the events (so splitting up sources and targets of the connection). This second MQTT connection would get both, HTTP API caused events and the events caused by the source MQTT connection.

Oh, that makes sense.
Thanks for your reply!
