    Default Path to Energy Consumption Ambient Indicator

    In my new flat I have a skylight that runs from the roof to ceiling and at ceiling level there is some corrugated plastic sheeting. It doesn't look too attractive at the minute but I have an idea on how to improve it and at the same time add some new geeky stuff.

    What I had in mind was to replace the corrugated plastic with a translucent frosted sheet of glass and above it install some RGB LED lighting in the void. I have a CC128 current cost meter that I was hoping to somehow have Cortex interpret and utilise to control the lighting colour in the void. e.g. green for low consumption, red for high.

    Does anybody have any ideas on how to achieve this? I'm not familiar with colour changing LEDs but I understand that some can be controlled by a 0-10v output from an Idratek 0-10V analogue output module? I presume there would need to be a new object for this scenario within Cortex?

    Hi Andrew,

    Im not familiar with the 0-10V dimmer packs but assume they work the same as the analogue dimmer packs that were commonplace before DMX was introduced.

    0v = OFF, 10V = 100% Brightness.

    If thats the case then you would need 3 analogue outputs to drive the indiviual colours and could mix any colour you desire.

    If the LED Dimmer pack only has a single 0-10V input then its possible that it creates colours based on the input voltage so to get individual colours you would need to know what voltages to send it, but if that was the case it would be in the documentation.

    BTW.... I would also include manual control so you can select the colour.... would be a bit expensive if you had to turn every appliance in the house on just so you could have a red skylight LOL

    Good point Thanks for clarifying the lighting side of things, I'll start looking around for suitable products. Can anybody shed any light on the Idratek/control side of things?

    We have a 0-10V RGB dimmer available. This controls each colour separately.
    We are currently working on a manual control for this. So you have three rotary controls one for each colour. There are also DMX RGB dimmers as well, which aren't that expensive, about 60 to 80 euros.
    IF YOU CAN'T FIX IT WITH A HAMMER, YOU'VE GOT AN ELECTRICAL PROBLEM.

    I think the main question will be how to get the output from the CC128 into Cortex. You might perhaps write your own code to receive and interpret the CC128 data and then use this to manipulate analogue output values via the Cortex API, or alternatively there might be some existing xAP route to get the data into a Cortex metering object. The latter has multiple threshold capabilities so that you can set different colours (analogue output value sets for the 3 R G B channels) based on different consumption levels.
