It seems that the leak sensors don't have macID in the response. I tried plumbing through a change to deviceID for everything as that seems to be universal for lyric devices, however that had other issues because the aiolyric library device lookup depends on macIDs. This integration doesn't work at all for me atm. Happy to help debug, I'm a capable dev, just not familiar with HA yet.

@balloob sorry for the @. This issue has been brought up twice (also in #52528) without a response from the code owner @timmo001. I'm a developer and happy to work with someone on the issue, but I'm not sure where to go at this point.

Ran into this issue today when attempting to add a couple of L1 WiFi Water Leak and Freeze Detectors to Home Assistant.
