Yeah its polling everything.
Its not chatty, you are asking it for info!
I think a good test might be to disable the polling on both of those device for a short while to see if it makes any improvement?
Also, if there is a custom driver for this device already, a custom command could be added that only requests the power value instead of everything! It may even work with the Power metering plug driver I have already created.
If you find a custom driver that works for it, I would be happy to modify it to add the custom command.
You could try this driver as well if you are feeling adventurous. [DRIVER] Zooz Smart Plugs Advanced (ZEN04 / ZEN05 / ZEN14 / ZEN15) I suspect it will work, and I could make a custom version for this 40 amp switch with a command that only requests the power reading. That would cut down the traffic 4x.
