Philio psm02 4 in 1 sensor with iu7

Hello everybody (and sorry for my poor English),
I have trouble with a Philio psm02 4 in 1 sensor with iu7 (veralite).
I finally succeed to install initially my Philio psm02.
But now i get a " Can’t Detect Device " message despite every motion works fine!
ON THE 3 in 1 sensor / 4 in 1 sensor.
In my dashboard i get 4 additional items to the previous :

  • Temperature sensor
  • Light Sensor
  • Motion sensor
  • door sensor
    Question?
    is it possible to delete the 3 in 1 sensor / 4 in 1 sensor.?
    is-it a setup for solving the silly message?
    thanks,
    Fran?ois

Did you try to restart device?
Initially I’ve got this message but when it restarted everything was fine.
It works great now.
