I have several Z-Wave switches that record among other things kWh for the attached appliances and I am finding I am getting more and more large spikes of kWh readings in the Energy Dashboard making it useless.

Here is yesterday, again all 3 readings are way out:
Any ideas what is causing this and how to prevent it?
