I’ve had a slowly growing smartthings setup that has worked very reliably for 3+ years. However recently just one single door multisensor on a bedroom door frame has started causing problems.
It’s a v2 door sensor of the previous design that is more sharp edged and blocky. My understanding is thst this is near identical technically to the latest version Samsung made?
Basically it goes offline constantly. Normally within a few hours of adding it to the setup.
It didn’t to start with when first installed… It worked fine.
It’s not the battery and it’s not even a speicific sensor device as I’ve actually tried multiple identical sensors on the same door frame.
What has changed which I think must be related is that I added a second Samsung v3 hub in an adjacent room fairly recently.
I did that for one specific reason; to allow another door sensor on our front door which is very close to the newly installed hub to work as prior it always seemed to be out of range of my original hub. It makes sense as this front door sensor is the device physically furthest away from the original hub with many thick walls between them.
What’s odd about the door sensor in the bedroom that goes offline is that if I take the battery out and put it straight back in, it starts flashing green and fairly quickly reestablishes a connection to a hub and then works. It doesn’t need resetting. It’s with a new battery that shows 100% constantly within the smartthings app.
So I have a few questions…
- is a multihub setup in theory going to work?
- are there going to be problems with a device that is likely in reach of both hubs? Is it possibly contacting one then later the other and for some reason getting confused and giving up?
- the behavior I’ve seen with how the sensor seems to give up and go to sleep ultil the battery is taken out and replaced is normal? What does it suggest?
- can I see somehow which hub the device is actually connected to?
Sorry for the long post but I felt I had to spell all the details out.
Thanks for any input!
