Thanks for responding. I removed and reinstalled everything to see if the problem continues. I still have the problem. I can see that events are being passed - the data is updating in SmartThings. However, the “Last Activity At” never updates. You can see my device - the lastCheckin updates as do all the other states but the “Last Activity At” remains equal to the “Date Created” and “Last Updated”. This is true for both the devices I have:
Is this normal behaviour or I am having a specific problem?
I have two methods of collecting data from SmartThings - one pushes the data out when events happen - this seems to be okay as the timestamp is generated by the event. The other is that I poll SmartThings, and here is where the timestamp always remains with the “Last Activity At” timestamp (I’m calling .lastActivity, which works for all other devices).
