Please.... Need help for Visonic MCT-370 SMA contact sensor and MP-841 motion sensor

Could be a failed pairing. See the community FAQ for how to find out. Take a screenshot of that info for the device so in case it’s not a failed pairing, you will know what your exact fingerprint is for that device.

FAQ: Manufacturer/Model Shows All Zeroes

If the pairing was good and you do see a valid fingerprint, then you will need to post that fingerprint in any of the other threads where you are asking about drivers, including Mariano’s. The developers will need the fingerprint in order to know whether their driver can help you or not.
