Blebox Integration: Add Floodsensor to supported devices / (= Blebox Water Leak Detector)

Hello! I came here from github (core->integrations->blebox). I hope I am in the right spot now. I want to buy a floodsensor from blebox to detect any leakage below the sink etc. immediately

I noticed that the blebox integration supports already a multitude of devices. However I did not see the floodsensor to be listed explicitly. Technically this should just be a binary sensor type of thing. (water is detected yes/no). But I don’t know if the simplicity of the sensor signal automatically means it is supported by HA or not.

Therefore I rather ask the question before buying:

Is the floodsensor already supported?
If not could you please support it?
(I would be also willing to contribute. I have no experience with HA yet, but work with Python daily on my job and could learn from the existing Blebox integrations to potentially make a PR for the floodsensor.)
