*by C***G on 25 December 2022*

The device was shipped promptly and arrived next day but unfortunately there was no user and installation manual provided with the contact sensor. completed a detailed search online and could not find the GRSICO app as well as any install instructions or a manual. I had no success with enabling the device in pairing mode which resulted in not being able to connect the device to my wifi network. Outcome: it appears the sensor can only be connected through a GRSICO hub.
