@steven Hi Steven, no it is not available in the Hub Actions in the Flic App. This is a module which can be used in the HubSDK with your Hub LR. Please check out this repo: https://github.com/50ButtonsEach/flic-hub-sdk-mqtt-js
And in case you are not familiar with the HubSDK, please check hubsdk.flic.io, https://hubsdk.flic.io/static/tutorial/ and https://hubsdk.flic.io/static/documentation/
@florianchazal Hi, thanks for your question.
We have a Device Manager where you can add and update modules to hubs. You can check it out at https://flic.io/device-manager.
Worth mentioning, that we have a new Device Manager version in the Pipeline which includes an open api that can be used for integration in CI/CD processes.

@ms Hi, please see the newest topic from today. We now provide an MQTT client. https://community.flic.io/topic/18233/release-of-mqtt-client?_=1674825212929
After getting a lot of requests about it, we now provide an MQTT client for the Hub SDK. This enables easy integration in your existing MQTT system and fast communication according to this well-known standard protocol. Additionally, this allows bidirectional communication with the hub. You now can trigger functions on the hub not only locally with your buttons, but also remotely from your MQTT system.
So go ahead, install it, configure your own MQTT client and tell us what exciting things you use it for!
