Contact Sensor Open/Close Issues

Hi All, I would like to see if I can get some contact sensor advise advise. Let me first articulate the issue, troubleshooting that has been done, and questions I have. Issue: I have a specific contact sensor that does not appear to timely be communication when it is closed. The firmware for the sensor and all other components are up to date. Upon research, also sometimes when it is open. This behavior has resulted in two false alarms when my wife and I set the alarm with a 180 second delay. Upon leaving the sensor sent an open log entry, but did not send a closed log entry timely.In both cases when the alarm went off, we had it disarmed. When we returned hours later, the original close entry showed up around the time we reentered the house hours later. (Not the time the door closed hours before) Additionally, while the contact sensor shows connected, while troubleshooting with ring we were unable to get either open or closed entry's to log to history. This morning however, the same test worked flawlessly and I immediately got open/closed history and notifications. I have now spoken to ring twice. In the discussions, it went down a path of cold weather. (Which is why now as opposed to 4 months ago... I live in Maine). The last support person is sending out a new magnet for the sensor although the magnet part is on a wood frame....but I am not convinced. My questions: 1) Are log messages held anywhere prior to showing in history? (My close was delayed by hours but did eventually show up)2). Is there any way to see the z-wave traffic and measure saturation of that network. (Open/close didn't work last night but did this morning) 3) Is there a way to measure signal strength of a contact sensor? (Distance from repeater or base station)4) Could the sensor simply be bad or immature technology or Other thoughts? thanks in advance for any help or thoughts.Craig Doering
