I moved into a house that already had Nest thermostat, Yale lock, Connect, and cameras. I have the thermostat and Connect all set up. I cannot get the Yale lock to connect. When I hold the button, it flashed blue three times then green twice. It never says 'Ready". It never speaks at all. It worked fine for the prior owner of the house.
I apologize for my late response and thank you for all of your patience while waiting for a reply. I'm terribly sorry to hear that you're having this issue, I understand how upsetting this could be, but I'm happy to assist you with this issue. I have an article that goes over how to troubleshoot the lock being offline.
