Hi,
I have created a TCP Client in Python that responds to button clicks from the Flic Hub. My idea was to create an Integration to HomeAssistant, but I haven't had the time to finish it. So I wanted to share the python tcp client for other people to use and improve.
Pull requests and feedback is appriciated

I have made a lot of updates to the Home Assistant integration. Here's some screenshots showing the entities it will add. Each button and the Hub will act as a separate devices. The click type is an attribute on a binary sensor on a button.
These entities will help you setup automations based on click type and also keep track of when it's time to change the battery, for example.
Once the js-script is added and started on the Hub and the integration is added in HomeAssistant, the Hub will automatically be discovered in Home Assistant and the buttons will be added.
@chris-3 Unfortunately I do not own a FlicTwist so I'm not able to add support for it. 
Maybe @Emil is able to help out here?
I wish there was a websocket or something similar already built into the Hub, that would make the integration a lot easier to add from a user perspective, at least until Matter support is released.
I started to make an Home Assistant Integration a while ago. You can find it here: https://github.com/JohNan/home-assistant-flichub
I never completed it completely but I think it should work partially at least.
It uses a TCP connection for communication that has to be setup on the Flic Hub. A linked repo is available in the above repo.
I also just noticed that Flic have released a MQTT client which should make it a lot easier to create an HA Integration. I might give it a shot to convert this one to using MQTT instead.
