Hi,
we have a MQTT Broker (TBMQ) with 3 Instances. We run Chirpstack with 3 instances, too. Now when I'm using MQTT Downlink I get 3 downlinks queued on the device. My best guess is, that the MQTT Broker sends the donwlink to all 3 connected Chirpstack instances.
Is there the possibility to use a "shared subscription" in the chirpstack.toml same as in region_xxx.toml, or is there another solution to not queue 3 downlinks?
What I see is that it is possible to use shared subscription in the region_xxx.toml file for topic:
gateway/+/event/+
I don't see that feature in chirpstack.toml. Shouldn't it also be possible for downlinks on topic:
application/{{application_id}}/device/{{dev_eui}}/command/{{command}}
???
@brocaar could you help me here, either to find the right way, or to think about that feature?
