Same here, i am using flespi.io mqtt broker. Everything worked fine until i missed some events from last night. In the helium console i saw that lora uplinks were received, but they had "integration errors". In the logs of flespi.io i can see every few seconds this pattern:
mqtt session connection was accepted
session has subscribed
mqtt session connection was closed
In the DEBUG of console.helium.com i see
Debug Response
{
"id": "0023300d-4fc1-4a5c-862c-62f349e05464",
"name": "flespi",
"status": "success"
}
so it looks like it's basically working. But the constant connect/disconnect is no correct behavior imho. And maybe because of this uplinks forwarded to mqtt integrations can get dropped.
Addendum: i just deleted the integration from the flow and the sessions disappeared from the console at flespi.io. After adding it again, the same happened as before, disconnect/connect/disconnect/connect/.... but...before it happened every ~5 seconds, now only every ~30 seconds.
from console.
I installed my own Mosquitto server. From the debug log i can see that Helium creates a client for every device (and subscribes to the tx topic) linked to this integration. So far so good.
But every few seconds new connections are established:

You see that "client ... already connected, closing old connection". Why? I see no reason why a once established connection should be periodically re-established. The only scenario which comes to my mind is: lorawan signal received -> function executed -> integration called -> mqtt established -> payload published -> mqtt disconnected.
But this is not the case here, there are mqtt connects without any reason.
I guess i found it:
I have a function "heartbeat" which creates an object with just one attribute, indication that this is a PING payload. This function is called in parallel to the real decoder function. So when there was a Ping event and no corresponding event with a data payload then i know that my decoder has crashed.
So if there is one device class, i have two edges connecting to the integration. One from the heartbeat, one from the decoder function. And the helium console opens an mqtt subscription for both. It takes the device-id and uses it as the mqtt client-id. So there are two connections with the same client-id fighting each other. Even splitting the integration in a data-mqtt and heartbeat-mqtt does not help, because the mqtt server is still the same. So i am using a dedicated mqtt server for the heartbeats.
