Z-Wave Aeon Labs Clamp Power Meter (Wrong metering)

[Guest Roman]

Hi.

 

Now, we started to install clamp power meters from AEON.

At the first view, it works really cool.

When I turn on my fan, or boiler I see proper value of consumption. Because I know fan is 1800 Watts, and boiler about 2000 Watts.

So value of current consumption looks realistic.

 

But, our problem started when we checked consumption for 1 week.

As additional info, we installed several devices for different customers, and all of them has their own hardware electric meters.

And of course we wanted to see same value for z-wave meter, and usual hardware meter.

 

But unfortunately (I don't know why) z-wave meter shows smaller values.

 

I'm sorry for probably stupid question, but is it okay to see such result?

 

1. I have new meters with 1.8 firmware.

2. I tried to modify different parameters like update intervals and so on.

3. Double checked connection according to manual.

4. Difference between values - something like 200%..

5. How is accurete your AEON meters? Have you compared calculated Watts/month with you electic bill?

 

Thank you for reply.
