What do I do with RFLink?

Ok I built a 433 mhz receiver transmitter with an Arduino Mega board. My hope was to use it with my Govee water leak sensor. I haven’t tried transmitting yet but I think I have the receiver working. I could only get a response from the RFlink application in debug mode when I press the Govee sensor button. So I installed the integration in HA with the setting for auto adding. I am detectin hundreds of entities but have no clue what they are. I can’t seem to distinguish my Govee sensor. Am I really detecting all these entities in my neighborhood? There are multiple ones with the same base name but they have different id’s. Are these the same entities and they keep changing ID? This is really cool but I don’t know if I’m receiving garbage or these are all real? And I’m still no closer to working with my Govee water sensor. Can anybody help with decoding all these entities? And ideally how can I integrate my Govee leak sensor? Any help would be appreciated.
