Emonwrt3 Web Interface

The web interface for the Emonwrt3 is integrated with Luci. The OpenWRT configuration interface.

This page only covers the web interface for the use of Emonwrt3. it does not describe other interfaces available for OpenWRT configuration (Status, System, Network, Logout).

General

Select emonwrt3 | General to get the some general settings. Some parameters are read only on the page intentionally as we believe they would not need to be changed for common usage.

Serial Port and Baud Rate are for the serial communication with the Arduino controller.

Rolling Database is the path and filename of the database to use for acquisition. If installed under /tmp this will be deleted for every reboot. To keep it persistent over reboots install it under /root.

Database Size (samples) is the number of samples to keep in the database. The default 128 means that 128 samples are kept under storage for resend in case of an eventual failure send. If data are received every 10 seconds this means that the last 1280 seconds are stored. Consider memory usage on the device before increasing this number.

HTTP Send Interval (s) determine how often http data are sent to the servers. This is in seconds. Default is 20 seconds.
