@Emil
Thanks.
I understand that this process will also delete any buttons that were associated with the Hub.
I have a few buttons that I want to use with HomeKit and others that are currently doing other tasks. Will I need to reprogram them all?

Re: How to use my flic buttons with Homekit AGAIN ?

I have the same issue described in the previous post by business2.
I need to reset the HomeKit association of the flic hub, so that it can be re-paired with HomeKit again.
