About

Nellin controllers

Features
Read full description

Nellin lets you set up and monitor kiln firings from your phone. The app connects to your kiln controller over the local network and keeps the essential firing data on one screen. Track current and target temperature, program stage, and heating progress. Select firing programs, adjust controller settings, and receive alerts when a program finishes or the device needs attention. The app also includes maintenance guidance, reference information, and a library of useful firing profiles. Initial setup uses the controller's access point; afterward, the app discovers the device on your local network. Your phone and controller must be connected to the same local network for control. Available features may depend on the controller model and firmware version.
