New Linear WS15Z-1 will not pair to Vivint branded 2GIG panel. Switch works fine stand alone. Attempted to pair by moving panel to vicinity of switch but still does not find device. Per a conversation elsewhere on this site, process to remove device was done and device was not installed with a live circuit so I don’t believe internal fuse to be the issue. Vivint says if it didn’t pair, it is not compatible but it sounded to me like a standard answer and not necessarily definitive.
It is possible this is a firmware issue. What version do you currently have on your panel? Is it the current V1.13? If its an earlier firmware, the equipment may not be supported.
