Execute Terminal Command fails in BetterTouchTool. Why?
I feel silly for not figuring this out myself, but I'll post it here in case anyone else is having a similar issue.

In Terminal, I can simply type this command and it works:

wemo switch Myswitchname toggle


But with the Execute Terminal Command in BetterTouchTool, it needed to be entered this way in order to work:

/usr/local/bin/wemo switch Myswitchname toggle
