I have found the problem
I was using a wrong variable in 1 line of code, hence the strange large negative number

will get a new update uploaded, and let you know, stand by

Hi Brian,
Downloaded the right zip this time.
Get message ...Power Count = 0.
I know the counter is working.
I'm using Page=15 used http://www.mrsoft.fi/ohj01en.htm to verify.

Cheers
Peter

Hi Brian

Here are the logs out of the WS2010-13/WS2500 debug.
I looks like it's working ok now i.e. the numbers are changing per the power load which is a good start.
Just to confirm - Are the numbers below from the log the amount of counts per minute?
25.5    
17
15
16
18
17
22 - Air con turned on
25
33
59 - not sure what happened here. It was missed by a minute.
29
34 8:18:58pm
30 8:19:59pm
32 8:20:58pm
28 8:21:57pm
33 8:23:55pm

The image attached shows what the Current Usage is shown, however that number is very low?
Going on the assumption for the numbers above are thw counts per min this is what I would expect shown in Watts.
25.5 1912.5w   
17 1275w 17x1.25x60mins
15 1125w 15x1.25x60mins
16 1200w 16x1.25x60mins
18 1350w
17 1275w
22 - Air con turned on 1650w
25 1875w
33 2475w
29 2175w
34 8:18:58pm 2550w
30 8:19:59pm 2250w
32 8:20:58pm 2400w
28 8:21:57pm 2100w
33 8:23:55pm 2475w


1.25 value is got by 1000w "1kwh" / 800pulses = 1.25
(800pulses - needs to be a variable to be entered by the user)


Hope this makes sense lol.

Cheers Daniel

ah, I need to multiply by 60 then
is the value being plotted?
(but will be too low)

the calc value in the 1 wire setup is also a 5 minute average/...

I have had a few "blobs" show on the graph.

Brian,
 Have downloaded the main .exe Version on 23 March 2010 - 10:09:06 .
 But power stuff not working for me.
 Have I got the correct zip?
 Any boxes to tick.

Cheers
Peter

ps The counter works in another 1 wire app.

Itís working ok for me however Iím getting a few spikes - see previous posts.

Have you tried putting a jumper between the counters A and B so they both count?
The other issue, make sure you have the 1-wire control panel closed; it seems the counter stops when this is open.

Cheers

I have also tried without success, it continues to show Power Count 0, port A and B is connected together, and have restartet the PC have you any suggestions?
I have a ABB meter which gives 100 pulses/kWh so Ratio Calibration factor is 10?

Cheers Tommy
