# Electrolyser (EL 2.1)
# Remote Monitoring and Control
Electrolyser EL 2.1 comes with pre-installed UCMs (Universal Communication Modules) that allow users to monitor the device. Over-the-air updates ensure that the latest protocols and security fixes are supported.
Pre-installed UCMs connect 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 customisable dashboards.
Enapter’s mobile application ensures quick and easy installation of any energy system. Users can manage the EL 2.1 via the mobile app and will receive push notifications to warn of energy system issues.
