Adding a Plugwise Smile to the Fibaro HC2

Yep, I’m still alive 😉 The ‘silence’ since April this year was simply because I really needed some sort of ‘sabbatical’ after almost 10 years of spending a great deal of my spare time to Home Automation – and some other (more important) things happened in the past months as well. But last week something happened that brought back the inspiration to write a new post.

I think it must have been about 2 weeks ago when Marco from Mood LedLight contacted me to help him to get some information the Plugwise Smile can provide into his Fibaro HC2. He was probably inspired by my post about getting Smart meter data into a HC2. And Marco is the one that advised me on my Gazebo LED project some years ago and he’s my LED strip supplier. I don’t own a Plugwise Smile but thought I’d give it a try – if it can be done I should be able to do it, right? 😉

Marco sent me some info about the progress he had already made – he used a PHP script to query the Smile and write the result to a file on a Windows 2008 IIS server and read that file from a lua script in a Fibaro virtual device and actually wanted to get rid of the PHP part.

The only part I did was getting the authentication working so that it was possible to get the Smile XML data without the use of the Win2k8 Web server. For the last part, XML parsing in Lua, I didn’t have enough time so I asked Marco to seek for help on that from the real Fibaro Lua script cracks – cause I only know the basics. 3 days later Marco had found the solution; here it is… have fun!

    Looks really good! Well done!

    I don’t own a Plugwise Smile, bit is it possible to import this data in the native energy usage screen fro fibaro?

    • Robert Hekkers says:

      I don’t own a Plugwise Smile either and I don’t use the HC2 myself, so I can’t really answer your question, sorry!

    Welkom back Robert. Love to read your blog and am happy its live again.
