Outdoor contact sensor

I’m wondering how I can arm an outdoor contact sensor without arming my back door sensor that we use during night

Hi @Robfirstaid. The only way to do this would be to set your Outdoor Sensor to be monitored and your Back Door Sensor to not be monitored for the Mode you want. When you want your Back Door Sensor monitored again, you would have to go back to the Ring app to toggle it back on.
