I have a bunch of devices set up identically and tracked in the Energy dashboard.
One device — Study AV Unit — has ‘untracked’ in parentheses after its name, only in the ‘individual devices detail usage’ graph.
It seems to be being tracked fine. Its energy usage figures increase and decrease as expected, and ‘untracked’ doesn’t show anywhere else, including the total usage graph.
(untracked) means that this is the amount of energy from that device that was not tracked in a downstream device. It’s not indicative of a problem, it just means that you have assigned children to that device.
So if AV Unit consumes 3kWh, and a child device consumes 2kWh, then you will see 1kWh (untracked).
