For each sensor you can set the mode for that sensor for the alarm - home and/or away. You can also set up notifications. Sounds like you may need to check these settings. In the app, go to devices and look at each sensor.
We have the same issue with my motion sensors. We are still in the seven day set-up period, before the monitoring begins. Last evening, we tried setting the alarm using the keypad. I activated the alarm and waited the pre-set time for it to arm. Then I walked into the kitchen, where one of the sensors is located. Nothing happened. Then when I opened a door that has a magnetic sensor, the alarm sounded.
Hey @Redlocks! From the main page in your Ring app, open the main menu (top left), select "settings", then select "modes". Once you choose home or away mode, you will notice the option to see which sensors are included in this particular mode. You may also choose whether a sensor will be included in the mode. I hope this helps!
Thank you for your reply. All went well until I selected "Sensors" in Away Mode or Home. Neither of those modes show My Motion Sensor. Those modes show all my Contact Sensors on my windows and doors but no evidence of my Motion Sensor. Thanks again for trying. I'm open for any other suggestions if you have any.
