It should be possible to make the alarm ring on all devices, when a motion is detected. It’s kind of useless, when the alarm in the basement is on and the homebase is on a second floor with a closed door. So it would be great that all cameras will ring. Eg. the two outdoor cameras. This only will alarm the neighbors.
@C.m28 This is already possible by a combination of “modes” and “automations”. Choose your selected camera in the basement and mark it to alarm the homebase when it detects motion. Then setup an automation that triggers all the cameras to alarm when the homebase alarms.
This way if you get movement in the basement, you will hear it on each device/unit. Hopefully the location in the basement doesn’t pick up any unwanted motion or you will have several false triggered alarms going, lol.
