Does anyone know how to physically locate a Zigbee sensor that could be placed in your home OR potentially a neighbors home? I have a Contact Sensor Visonic MCT-350 SMA adding itself to my HE. I have only (4) of these devices and they are all accounted for. I have also double checked the Zigbee ID in case I am dealing with a potential ghosting and none of the IDs are identical.
Also could this be my ST hub? Just curious for any advice.
Great question! I added a rule to notify me if the contact opened as I can't find it anywhere. I only own (4) of those contacts and all are accounted for.
Seems like an active device. Your theory of a neighbor’s device sounds somewhat plausible, assuming the neighbors a pretty close by. Do you know if any of your neighbors are into home automation?
Also try going into Zigbee setting and click on Zigbee logging. Compare the signal strength of that device to the rest. Possible it's weaker than the rest could point to your neighbors or strong for a spare you have forgotten somewhere.
So I let this run a bit and the results are below. I have no idea what the numbers mean. Is the number closest to 0 better? Example my HE is in the same room as the Office Zigbee device.
Also no idea where this generic contact is located. Ugh!
It seems a bit uncanny that you would click "Discover" at the moment your neighbor was clicking the pairing button, and he or she didn't reset their device when it didn't show up in their system.
I think that sounds a bit too far fetched. Must be a different cause, but sorry, I don't have that explanation or even a hypothesis.
I don’t think the ST hub would be sending temperature updates... speaking of temperature, do those temperatures help to determine a location. 62 degrees seems a little cool for an indoor sensor.
I had the same thing happen.
Local security company uses Visonic sensors.
Likely lost connection with their hub and then rejoined to mine.
I just deleted them and they have not come back.
If it’s cold outside, close the door to a room and open the windows. Then watch the temperature to see if it drops. If not, try another room. Repeat until you find it.
I'm not a ZigBee expert by any stretch of the imagination but I have a few thoughts:
If it is an errant sensor from a nearby neighbor then it will not show up on their system. I assume a ZigBee can only be paired to one hub at a time.
If I had such a problem I would simply shut down all four devices one a time and see what the hub thinks. If all four were disconnected (battery removed?) and your "extra" device was still there, I would simply delete it and see what happens.
I continue to delete it but it comes back automagically. I believe Zigbee enables devices previously connected to connect again. I know my neighbor had a security system from both Vivint and now Xfinity installed. He had the newer implementation which used a lot of Zigbee and Zwave devices. Worst case scenario is I name it zzzzzcintact and not really ever see it in my list per se’
