IO Home Control appears to be an 868MHz band RF control protocol - looks to have been concocted by Honeywell but not adopted by so many. Honeywell themselves use other protocols. Anyhow it is not a simple protocol of the HomeEasy, Lightwave RF ilk (which operate in the 433MHz band BTW). So I think its going to have to be via the KLF 100 or preferably the simpler looking KLF 050 since the other features in the KLF 100 are probably not needed.
