Apologies for yet another Arrival Sensor thread but a search did not find what I’m looking for.
I have two SmartThings Arrival Sensors. I’ve had them a few months and as many report, they have had a habit of doing the left/arrived dance and this is most likely due to Wi-Fi interference although, I should make it clear I do not suffer from interference with the rest of my Zigbee devices as far as I can tell - pretty sold mesh including a plug-in repeater very near the garage where the sensors ‘park.’
The left/arrived dance seemed to get worse as the batteries ran down. I just this past weekend modified both sensors to run off of external AAs as several in here have also done. When I did this I had a slight issue with the sensors rejoining the network even though what I did was basically the equivalent of changing the batteries. For both sensors following the battery mod I had to do a trick I had read about in here whereby I set ST in to add a device mode and then insert the batteries and tap the sensor button (like adding them for the first time). Whether it’s fluke or that’s an actual solution I have no idea but they finally both rejoined and showed as arrived afterwards.
However, only one of the sensors has remained steady in that it is reporting left and arrived as expected (and so far no ghost left/arrived events hopefully as a result of the battery power being back to 100%). The other sensor is acting up though. For the latter the following has happened:
- Event one - I left the house. The sensor registered as left as expected. When I got home it never registered as arrived. I had to do to the trick described above again to get ST to see it as arrived.
- Event two - I left the house. The sensor registered as left as expected. When I got home it DID register as arrived. Then a few minutes later it ‘left’ and has been that way for hours. I have not yet tried to include it again until I try an understand more of what is going on. I do know it still has power (in other words the battery mod has not failed).
Again, both sensors did left/arrived just fine before the battery mods even if they did do the dance quite a bit.
Any ideas what is going on with this second sensor?
