According to the author, there is now an new updated Insteon Health Test Tool for Indigo v5…
iHealth UPDATE
I have just submitted v1.2 of the iHealth tool to the Contributions LIbrary and it should be available later this week. I have also placed a temporary copy on dropbox.
This version fixes two recent problems with Lion and Indigo version 5. The Perl libraries are properly linked and the Indigo INSTEON interface is now correctly taken off line.
There are no feature changes, so if your current version of iHealth is working properly there is no need to upgrade until you switch to Lion and/or Indigo 5.
