New power calculation for pulse meters.

Hello!

Been using the Flukso for a couple of weeks now and it works really well. I've started to experiment with the local REST API to get measurements out with 1 second resolution.
It works ok, but i think the accuracy could be improved. I'm using a 2000 pulses/kWh electricity meter and during some earlier experiments (before using flukso), I got really good results by measuring the number of milliseconds between pulses and use it as a base for power calculations.

optical reader for power meter

Hi,

I am new with the flukso. I have a power meter with a blinking LED. I was wondering whether somebody has already a solution for getting this LED pulse in the flukso. I attache a picture of my power meter.

Thanks in advance.

best regards
Andreas

What development environment is best to compile

Hello Everyone,

I am brand new to Flukso and am interested in playing with the device. I am trying to compile the source and coming up with a problem that I am hoping to get help on.

  1. make[3]: Leaving directory `/home/ubuntu/workspace/flukso2/bin/flm02.1.4/package/linux-atm'
  2. make[2]: Leaving directory `/home/ubuntu/workspace/flukso2/bin/flm02.1.4'

jsonp with local realtime interface

hi Bart,

Great time at the electro bar camp!

Today i tried to get the jsonp interface working, but i failed to get the same results as you describe in the manual. When i make the following call to the local realtime REST api i do not get the json function name before the json data. In the example in the manual it does. This blocks the option to make a call to the flukso from a webpage served on another web server in my house. Do you have any suggestions what i do wrong?

 

Graph colors

It would be nice to be able to tweak the graph colors.

If too much work, could you in the short term change the color for sensor 4? I've been adding more sensors, and number 4 is bright yellow, which is a great match with the white background ;)
