I have updated to a C8 Hub (2.3.7.145) and I've been having problems with my SmartThings Multipurpose Sensor V5.
I have reset them all which was the original issue I ran into when I moved to the C8 hub.
I now find that the temperature and battery values wont update unless I go and push the refresh button on the device. I can see the contact attribute does report open and close as I do that.
I do have 2 out of 7 that do in fact report correctly.
Firmware seems to be the same.
endpointId: 01
application: 11
firmwareMT: 1241-0020-00000011
manufacturer: Samjin
model: multi
softwareBuild: 00000011
Any suggestions?
I've now started hunting for a cheap Samsung Hub to try a firmware update.
You could try re-pairing the device. Don't remove it first. With Zigbee devices, they'll slide right back into place.
An even easier possibility is seeing if running the "Configure" command helps. (Re-pairing will also do this, but these devices should also be listening for it on their own.)
My smart things sensors stopped working with that firmware update as well. I was able to add them back into the network but they don't operate correctly and I've had to replace them.
