Trying to integrate Hama Motion Sensor

morning hass people!

I have been trying to integrate a Hama Motion Detector (176554) with HA without success. I have tried the tuya app but my device doesnt show there, so I am left with a wifi device that only works inside the Hama Smart Home (“HSH”) app.

Anyhow, it’s connected to my Wifi, and it even has its own wifi (“Smartlife-…”) in pairing mode. My question is:

Is there a generic way to register devices by IP and/or a generic pairing for devices which can connect to their wifi when they are in AP mode?

a somewhat dirty idea as a fallback will be to track network packets sent from the detector ip, but that is really dirty and very likely unreliable.

things i have tried:

  • linked HSH to google assistant, but device doesnt show up in ghome
  • linked HSH to SmartThings, but device doesnt show up in smartthings
  • installed tuya, device not recognized
  • installed localtuya, unable to connect to IP
  • added device in NMap integration, but this integration just pulls network info and therefor nothing i can do with it to detect motion except when using a dirty --packet-trace which is quite unreliable.
  • as for the simple nmap scan (the default config), it actually doesn’t recognize this device (but a lot of other ones) because all ports seem to be closed on the motion sensor device. Otherwise, having the device in here would be enough to recognize on/off state…

[EDIT]: The reason why I am considering the “packets watch” is that I was able to detect a pattern in network activity for detected movement (basically, the device receives many packets over wifi when a movement is detected (> 20) ; but when it’s in standby it will receive only timed single packets.)
