You might need to update the firmware on your plugs.
The Update Firmware process is a Hub operation, to see the logs for the firmware update process you'll need to go to the Logs page and filter on the Hub entries.
You can check your current version on the Device Data section, this is my updated today non power reporting 3RSP019BZ plug showing Software Build 10013065:
johnwill's method of finding the Refresh is no doubt solid (and is sometimes the only way), but for most devices that expose Refresh, it can be set up from Rule Machine's 1st-level "Create New Action" menu... This may be a wee bit of a timesaver.
But it's odd that a mains-powered device is not reporting its status properly... Is this a power-reporting plug or just a basic on/off model? What driver are you using for it?
They do report power usage, but I don't know if it is accurate or not.
I am using the "Generic Zigbee Outlet" driver - assuming that is what is listed under "Type (currently system)" on the "Device Info" page.
These were my first device purchase so I was pretty uninformed, could be they are a poor choice. They seem to work just fine except for the status-reporting thing.
That should be a good driver in general (I use it for my power-reporting and basic on/off Innr plugs), but I don't have any experience myself with Third Reality plugs.
As long as their performance otherwise is OK and you're not seeing any other misses in your zigbee mesh, then it should be fine to let ride.
