@NotYetRated I started with autHomation and still have it but I been using ImperiHome 90% of the time now. Until recently I couldn't use it full time due to not having multiswitch support. But now I'm I can almost say I don't need autHomation.

I'm also following along interested in the Temp, Humidity, and motion sensor.

I blame UI7 and have no idea why people use it. So many problems and I haven't found one advantage or UI5 yet.

Thanks for that info, it seems to only confirms that the meter is working right and that my problem is in the sktech. LOL

I really need help finding out why the example sketch with the "1000 blinks per kWh" set doesn't work anywhere close to where it should be.

I'm using the example sketch and my meter has 1.0kH tag on the front.

i'm so lost on this. I can read the screen on the meter. I got my meter holding down to around 1.31kW according to the meter read out. I set the timer for a minute and counted the flashes on the LM393 LED. It flashed around 26 times in that min. So 60 min in an hour that's 1,560 flashes per around 1.31kWh..

Next I kicked on the AC and let the Kw reading on the meter level out around 3.10kW and then I set the timer and counted 54 pulses per min. x 60 for 3,240 per hour.

Everything looks per proportional and right along with what I found on the internet for this meter.

1,000 blinks per kWh.

Using the factory settings should put me right there is what I keep thinking. But that gets me showing 300,000 watts

using your above formula and pulses still at 1000 it still gets me in the 300,000 range.

If i change my pluse per KWh to 100,000 then it gets me into the right area at 3000 watts when my ac is on which is in the ball park but if I turn the AC off and kW drop to 1.3 ish

The serial is still showing 3,000 range in watts it wont drop to the 1,000 so watts it should be.

If you can't figure out how to post pics here, post them in the Vera Forum. Has anyone tried to help you there?

I'm on ui5 so i'm not sure how much help I can be with UI7.

UI5 was easy to get files installed and loaded and create a new device. I didn't get any startup error. But I did run into my NANO not creating a serial port in Vera so there was no option for me to make the association. Sounds like you might no have even gotten that far if you don't get a serial error.

Even without the serial connected to the VERA or the sketch on the serial nano. you should still get VERA to take the plugin and not get a start up error. You will how ever get a serial port error.

So I think your problem is VERA only at this point, having to do with the upload files and new device.

Post some screen shots so we can confirm tho.

Hoping can jump in and shed some new light on this. BUMP!

watt = (3600000000.0 * ppwh) / interval;

Well i put the Pulse count back to 1000 then I changed the formula above and now I'm getting some wierd up and down readings even tho the meter was fairly stable during this time.

@John so I'm a bit lost (not surprised) at your formula. Can you throw some numbers in your new formula based on my information above (or fictitious numbers for an example) and give me an idea of what it should look like.

@korttoma it sure doesn't seem like if fixed much.

I'll include some pictures but I don't see anything anywhere on the meter that might give an indication of the pulses. And def. nothing around the IR. I'm also confused now how even when I got it reading right at higher usage. It didn't drop down much after I cut the usage and was still given a high reading.

Well I found out meter will read the kW in 2 decimal points. It was reading around 4.3kW with the ac running. Reading the serial seeing what it was outputting vs what the meter was reading I started adjusting the sketch then uploading then reseting the sensor and re reading the serial. I got it reading about spot on with 105000 flash per KWH.

The. I shut off the AC kW reading on Meter went down to around 1.3 ish but the serial was showing 3,011 watts or something. So it didn't change in perportion. I do know the flashes slowed down but didn't recount yet to see just how much. Maybe 1 flash ever 2 seconds now. It definitely didn't cut it into quarters from 4kw to 1kw.

Well it's defiantly my flash counts that's way off. I brought the laptop out to the meter and plugged in and got some valid info off the meter.
my flashes are more then 1 every second with a/c running. I counted around 30 in 25 seconds using a stopwatch.

During this time with sketch stock at 1000 it was reading.
Watt:285,623

Ofcourse I changed 1000 to 10,000 as suggested for a trial and it went to
Watt:29,373

and for kicks I wanted to get it into something more accurate so I changed it to 100,000
Which is now reading and updating right in VERA (ofcourse since it's not over the max)
Watt:2972

So I guess the trick now is trying to figure out what each blink real value is on my meter.
3,000 watts with 220v a/c running puts me around 13.6 amps.
I'm thinking for a few lights on,TV, fridge, ceilings fans and 3.5 ton a/c this is reading low now.

I don't have an amp clamp and havent figured out how to read this digital Itron OPENWAY Centron meter. It only has one button.

I think when I was using the tv remote it would flash like 4-5 times per each button I pressed so I'm sure the IR was just blinking like crazy.

Here is my actual usage for yesterday.

The test above is when I was bench testing inside the house with the sensor connected to the computer. I was using a IR tv remote to activate the sensor. So these readings can not be taken serious.

I do now know how yet to read the serial from the meter wirelessly (maybe I need to unplug the gateway from vera and read that, or take a laptop out to the meter and plug in there)

I did NOT modify the sketch.

I have an ITRON OPENWAY meter with IR on the top that is supposed to be "each blink on the IR LED is 1 watt-hour of power usage" now I found this info on a forum for the ITRON CENTRON that looks the same, but maybe this is where my problem is.

I then translated that to be
1 watt hour = 0.001 kilowatt hours
0.001 x 1000 blinks per KWH

So I thought I should be good with the default settings of 1000 pulses and left everything alone.

I guess I have a better idea of whats happening now. It's reading so high it's throwing out the data assuming it false.

I need to

1. probably just try the 10,000 vs. 1,000 in the pulse count per KWH.

2. learn to read the meter so I can count the blinks and the actual KWH and do my own math on the blinks needed.

3. take a laptop outside and attach the usb to the sensor while on the meter and see what the output is.

More info:
I want to say (ruff guess) with the A/C on it blinks almost every second so that's 60 blinks in a min and 3600 blinks in an hour with A/C running. (logging into my edison (www.sce.com) account and looking at yesterday's history for the few hours the A/C was running) I used 3-4 kWh (each hour) during the 4 hours I ran the a/c So lets say I average 3.5 kWh with an average of 3600 blinks per hour so The more I think about it I think that 1,000 number is right on don't you think? Or is my math off somewhere?

Well, I'll work on and post back in 2-3 hours with a new serial update and more info when I get home to do a test on numbers 1-3 above.

I setup an energy meter. Watts don't seem to be working right on VERA. KWH appears to be working fine in VERA.
Here is my readings when I'm bench testing.

I'm an android person but on the only apple device I own I use homewave a like it as I can customize everything.

Also ui7 causes a lot of issues and I would recommend looking in to downgrading to ui5 if that will solve any of your problems.

I have only had that twice. One time was a low battery and other was a range/wifi issue.

Thanks, I have looked into that. I'm thinking this my cause problems with my phones nfc with a tag stuck in front of it tho. Can anyone confirm this isn't going to mess with my Google wallet and other NFC activities of my phone?

I was playing around with the RFID sensor today and found that my NOTE 3 nfc tag is different each swip. I didn't want to carry a card or keychain tag. Was hoping to use my phone with a easy swipe. What are you guys doing for this?

I just ended up going to my local Fry's store and spending 35.00 for that "OSEPP Nano". Plugged it in and serial showed right up no problem.

So I can confirm the cheap EBAY (some not all) don't work out of the box like a more expensive one. Atleast foe the controller. I'm sure I'll use the other 4.00 one for a sensor.

No go just tried that.

@Dan-S. I have tried about everything, but its been a while. I'll try that again now. Thanks,

I still can't get my cheap ebay NANO to communicate with my VERA. (no serial showing up)

Locally I have a few expensive options but today is Friday and I have a ton of sensors I want to play with this weekend. My local radio shack has a Arduino Micro with USB on it.

http://www.radioshack.com/product/index.jsp?productId=17207736#

Looks to be a different processor so I'm assuming that's a no go.

My other option is a "OSEPP Nano" but since its a clone I'm worried of it having the same problem.

Whats your guys thoughts?

I'm having same problem with my clone NANO.

I can't get serial adaptor to show up in VERA. I have a powered hub with my VERAlite. I have a usb to serial already for my caddx alarm and usb flash drive for my logs. I have even removed the hub and tried only the nano to the vera. Powered down for a bit and restart. Never can get serial to show up. I can program the NANO and rear the data get a code and startup command.

Think its my clone? I have an extra UNO but haven't tried it as people said it needed to be a NANO hooked to VERA.
