ST215C controller with wifi
The ST215C with wifi offers the same as the ST215C but with the addition of the wifi feature which allows you to view your firings remotely via this link - https://www.kilnportal.co.uk/login/
This allows you to view the status of your controller. The Kiln Portal can be configured to automatically log all your firings, capturing the time/date of the firing, details of the program used and a record of the kiln temperature history. The Kiln Portal can also be used to upload, view, edit and download programs.
The WiFi interface also comes with a USB interface which allows logging of kiln temperatures to a USB flash (thumb) drive.
