    Hi jlo,

    Unfortunately Google did an update making it no longer compatible with our devices. we have forwarded the issue over our development team for a fast fix regarding the issue.

    You can use on Port 25 - provided your ISP does not block port 25
  • Any updates here? I've tried the on port 25, but must be blocked. Is there any other email service we can use in the interim? Scary not having a temp monitor...
  • See Google's URL - You could ask your ISP to open port 25 or use on port 465 or 587 if you have Google Apps

    In the mean time we are working for a solution in the firmware that would allow our units to connect to Google's mail servers
  • While working on a firmware fix for the latest generation of Sensorgateways, we have also been working on a fix for all versions of the Sensorgateway. We just launched the BETA version of our *free* Premium Email Alerts service. You can now use servers hosted by us to send out email alerts. Simply go to to signup and start using this new free service.
