Aeon Labs Home Energy Meter

Ok I am confused. Here are two Energy meters that appear to be identical except in price. One for $30and the other for $95. Both for sale at Amazon

$30 Meter
$95 meter

Update: Oops. The same question was asked and answered under the $95 item. Battery vs Hardwire, improved accuracy, more reports

Yes, and I wouldnā€™t doubt a new one with gen5 Z-Wave chip will be released soon to confuse things even more. Aeon doesnā€™t differentiate their versioned products well.

Yeah, at first the pictures looked identical for each unit. A closer look though revealed a AC cord for the higher priced one :smile:

I have the first version, and itā€™s pretty accurate. It can be battery or AC powered as well. The difference between the two are capabilities with v2. It does AMPs and a couple other things if I remember right.

I have a V1 and Iā€™m currently testing to see how accurate it is with the power companyā€™s power meter. $30 was easy to drop on it to monitor my tenantā€™s energy use in a couple of outbuildings.

I only get kWh in 10ā€™s so I canā€™t see a 1:1 comparison on the power companyā€™s meterā€¦ Iā€™ve logged 380kWh with it so far and the 10ā€™s place still matches upā€¦ so if we figure that itā€™s off by 9, max, then itā€™s still ~97% accurate (It could be more accurate, but my sample is too small)ā€¦ if I had 1000kWh and it still matches, we could figure it was at least 99% accurate.

I didnā€™t need to buy the V2 in this example, this proves that the V1 meets my needs.

What smart app you use to operate this Aeon Labs smart energy meter ?

7

Iā€™m not using any smartapps for my energy monitor use.

Iā€™m using a custom device type discussed here:

Specifically, Iā€™m using a cut down version of the app that Slowfoxtrot put together and posted here:

I now believe the meter to be ~95% accurate, by comparing my usage with the power companyā€™s meter. It meets my needs just fine. Iā€™m not sure if the Gen2 would be any more accurate.

Iā€™m going to double check my install of the clamps to make sure everything is solid. Maybe I can get the accuracy up a little.

So, you use this device without smartapp and just device that appear on ā€˜thingā€™ menu ?

What version of version 1 of Aeon Labs ?
Aeon Labs DSB09104-ZWUS ?

9

DSB09104-ZWUS - yes.

I donā€™t have any need for a smartapp with this device. I suppose maybe youā€™d want alerts if energy spiked? Not sure. All the information I need is displayed in the device menu thanks to the people in that thread.

thank you very much.

I just found ā€˜Energy Alertsā€™ smartapp for notification on wattage limit

Hi Erik,

Can you point me in the right direction for the most up to date Ver 1 code by chance for the Aeon Home Energy Monitor?

Thanks much!
Derek

Yep, Iā€™m using what @Slowfoxtrot parsed down from the V2 code. I think all he did was fork the code from @storageanarchy and hide some unsupported info squares.

Anyways:

Thatā€™s the one I use too. Works great, I even wrote my own smart app logger that logs its data to a private SQLdb & has pretty charts :smile:

Hey guys,

Sorry to bother you guys as Iā€™m not a serious coder, but I havenā€™t had any issues in the past creating SmartApps from code. Iā€™m taking that parsed down V2 code from the link you provided (all 427 lines) and creating a new Smart App ā€œFrom Codeā€, but when I hit ā€œCreateā€ I get the following error:

No signature of method: script14294150751122129033250.metadata() is applicable for argument types: (script14294150751122129033250$_run_closure1) values: [script14294150751122129033250$_run_closure1@6e59349f] Possible solutions: getMetadata(), getState(), setState(java.lang.Object), metaClass(groovy.lang.Closure)

Is there something I need to tweak/edit to get this to actually save?

Thanks for all your help! Sorry in advance if itā€™s something simple Iā€™m overlooking!

I donā€™t think this is a smartapp. Itā€™s a device type you need to create.

16

Yikes ā€“ sorry about that. :slight_smile: Will try adding as a device type now.

Thanks! - Derek

I just purchased the v1 for 25 off of amazon figured it was cheap enough to see if it would see my hub from the CB box, just wondering Iā€™m only getting Watts KWH stays 0.000 is anyone else having the same issue???

18

Check out this code ā€“ this is the device type code Iā€™m using that works with my Hemv1 hardware. The only issue Iā€™m having now is itā€™s only updating values once every 5 minutes vs every 20 seconds.

Thanks-
Derek

Still only showing me wattage and a second one I bought doesnā€™t seem to work at all. Maybe there both defective hard to believe but Iā€™m ordering a 3rd one just to see if the one that shows nothing is badā€¦

thanks for your help

I could be wrong, but I donā€™t think itā€™s the device. If itā€™s showing you the Wattage in Watts, thatā€™s instantaneous power. I think the device type samples that power (every 20 seconds, every minute, etc) and is supposed to automatically calculate the running total energy for the month in kWh.

At the end of the month, you reset the device and it resets the kWh back to zero and starts growing again. From kWh you can estimate your cost (i.e. 12-15 cents per kWh typically I believe).

Does that make sense? So it sounds like your hardware is working fine. Itā€™s something with your device type? Maybe try deleting everything, starting it again and letting it run overnight?

Hope this helps - Derek
