This seems to be an issue with the Honeywell 5822T tilt sensors. I have two of them attached to my two garage doors. I often see events in the activity history that shows as opened/closed even though the doors haven’t been opened or closed, or sometimes it shows “Open” even though it didn’t open. This also causes me to get notifications that the zone was left open. I do want to get these notifications if I indeed did leave the zone open, but in my case it’s not really open.
It appears that the SEM does not look at the heartbeat bit and treat it as a heartbeat.
For reference, during heartbeat it sends out this message: 0xa4 .
This should not be treated as a zone open as the zone is not actually open.
This indicates that it’s a heartbeat and Loop 3 is closed (Loop 3 is what’s used for the tilt sensor).
When my garage door opens, it sends the message 0xb0 (Loop 3 open) and when it closes it sends 0xa0 (Loop 3 closed).
I have these zones setup as Monitor zones, i.e. it won’t set off the alarm if triggered nor will it prevent me from arming the system if the garage door is open.
Is this a known issue with the Alarm.com Honeywell SEM or did I set something up incorrectly?
It may be hard to see but when it shows that it is opened on alarm, does it also show open on the keypad as well?
Do you have any wires connected on the terminal of the 5822T?
The first step I would take would be to try and delete the sensor from the panel and then learn it back in. Is this sensor new or has it been installed for a while?
Alarm.com does call out the 5822T with the following caveat:
Sensor Activity Monitoring (SAM) is not compatible with the 5822T Tilt Sensor. Turn off sensor activity monitoring for this sensor, if installed.
So it can work as a local announcement but it cannot be used for activity monitoring in Alarm.com. ADC does not specify why, but it sounds like what you reported is the reason.
On the Settings > Manage Devices page in Alarm.com, click on the elipses and choose device settings for that sensor. On the resulting page uncheck the box in the “Monitoring” column for that sensor. That is the sensor activity monitoring column.
I disabled monitoring for those sensors but still get “Sensor left open” notifications on my garage doors even though they are closed. I do want to know if I left my garage door open but currently it’s giving me false notifications.
Here you can see the notifications that I get about the sensor left open, even though neither were actually open.
Unfortunately if the SEM sends open status events on supervision intervals then this would continue to occur. The panel status would not reflect it is open unless it truly has opened, but in ADC unfortunately this activity would continue and any notifications would be incorrect.
The 5822T looks like it is basically only compatible with regard to alarm monitoring, the panel should report alarm events normally from it (if programmed as an alarm generating zone type) but its status in Alarm.com would continue to show open intermittently for sensor activity or any status notifications.
