@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/
@info-6 Thank you so much for reporting this, we will check this out and update the branch with this change!
@atruttmann Hi! Unfortunately this clashes with a build in functionality that after 8 seconds the Flic will disconnect and advertise in "Flic mode". This is to give users a way to connect the Flic back to the Flic app in the case you would not be able to disconnect it from the other device.
@jonasnordstrom Hi! This is fixed in the new beta version 5.5.3!
@jeff Hi! Sorry to hear about this! Could you check to verify that the Flic app has access to the local network? This can be done in iOS Settings -> Flic -> Trun on "Local network". If it is already turned on, could you try turning it off and back on again?
@jf Hi!
Could you describe at which step it failed? Did the RPi discover the Flic at all?
I don't have a RPi at hand but just tried with Kubuntu and did not see any issues.
Also to make sure, did you add it by going to System Settings -> Hardware -> Bluetooth -> Add new device?
@a-j-towler Hi! I have reached out to you through our support system (aka email), it's a bit easier to communicate there 
@samjay Hi!
Very sorry to hear this. Unfortunately this seems to be somewhat common with our HomeKit users, as you describe it seems that HomeKit does not realize something has changed.
The only way to completely re-do the HomeKit pairing from scratch is unfortunately to factory reset the Flic Hub. This makes it appear as a new device to HomeKit and hopefully into a working state.
To do this, locate the pinhole button underneath the LED on the back of the Flic Hub. Press Using a pin or needle, press and hold this button for 10-15 seconds. The LED should blink to indicate that it is rebooting.
Remove the Hub from the Flic app by pressing and holding on the Hub icon. Now re-add your hub and button and enable HomeKit for the button.
If you have performed all these steps and you still can't find your button, we strongly encourage you to file a bug report with Apple so that we can escalate this issue.
@ColCustard Hi! This issue should now have been fixed in the latest version of the Flic app for iOS!
@na51hog Hi!
This issue has finally been resolved by SmartThings, authenticating should now work again!
Sorry for the inconvenience!
