  • Unable to connect via MQTT using topic name with $filter/payload==group...

I am trying to access a filtered group. The topic is "$filter/payload=group%3D%3D%224444%22/flespi/message/gw/devices/#" but using this topic as is with either a Kafka MQTT connector or another MQTT client, this topic name is not being accepted and no data is flowing, even though data is visible with this filter in the flespi portal.

Can anyone advise how I can encode or otherwise amend this topic name so that I can consume the MQTT message off this flespi filtered topic using an external MQTT client or the Kafka MQTT client?

Many thanks
Cliff

    I just tried to subscribe using the MQTT Explorer client. Everything worked without any additional configuration.

      Thanks for your feedback. I suspect that some MQTT clients will accept this topic naming method while other won't. There is no error being reported when I try (I've tried the MQTT.Cool client and the Kafka MQTT connector, which isn't a client directly but effectively acts like one).
