📈 Remote Monitoring and Control

Introduction

Dryer 2.1 comes with pre-installed UCM (Universal Communication Module) that allows users to monitor the device. Over-the-air updates ensure that the latest protocols and security fixes are supported.

Pre-installed UCM connects to the Enapter Gateway and send performance and error data to the Enapter Cloud. The data is stored in a time series database which displays it real-time on customizable dashboards.

Enapter's mobile application ensures quick and easy installation of any energy system. Users can manage the dryer via the mobile app and will receive push notifications to warn of energy system issues.

Network Requirements

WI-Fi Requirements

• 802.11a/b/g/n (2.4 GHz only)
