here my config.json (config.json is validatet):

{ "platform": "SmtpSensor", "port": "2525", "sensors": [ { "name": "Kamera Eingang", "keyword": "IP Camera 002-050-207" } , { "name": "Kamera Kellertreppe", "keyword": "IP Camera 002-050-212" } ] },

thx neo

Seems the author may have gone silent but i found the solution. The plugin gets installed under the ~/.homebridge/node_modules directory instead of the /usr/local/lib/node_modules directory.

Performing "cp -r ~/.homebridge/node_modules/homebridge-smtpsensor /usr/local/lib/node_modules/" allows it to load and homebridge to complete startup.
