Yup - I monitor energy / power using 1-Wire and have set up around 30 temperature sensors using an EDS 1-Wire Hub and the amazingly useful One Wire File System (OWFS).
Would be interesting to have energy monitoring integrated into LinuxMCE using 1-wire methinks.
I'm waiting for a 1-wire solar sensor- so would like to somehow be able to control the light brightness this way as well. At the moment my 1-Wire server is separate from the LinuxMCE system - if I could tap into LinuxMCE using perl (ala MH) my life would be complete. - I cant get derailed-rhouse to work for ruby
by the way how else can control devices from a scripts -please can someone point me in the right direction
