core: Lowes Iris / Centralite Zigbee Plug (3210-L) Sometimes Reports Wrong Values for Power

The problem

I have several of these plugs. They are the Lowes Iris 3210-L models which are made by Centralite. 80% of the time they report the correct values for power usage. However, every few days, often after a Home Assistant restart some of them start reporting the wrong power usage. Basically 10x the actual power usage. Not all of them will report the wrong power usage at the same time. For example, when I inspect the device I can see that the "active_power (id: 0x050b) is 1419 and the “ac_power_divisor (id: 0x0605)” is 10. The killawatt meter is reading 142 watts, so it seems it is not doing the math. I’ve check other devices when this is happening that seem to be reporting their power usage fine and the values are similar. “active_power” is 10x what that killawatt reads, but the device in HA displays the correct power level as if the math is happening.

Currently I have about 10 of these plugs installed and they are all reporting fine except for this one. Sometimes it is more. Sometimes it is other plugs and not this one. Also, some of these plugs are identified as a “light” and others as a “switch”. I can’t tell if it only happens to one or the other, but I seem to remember it happening to both.
