Important Security update

This latest release includes an important security update to the way apikey’s are created and passwords are secured in emoncms. The key generation functions used have been updated to the newer cryptographically secure php functions. It is recommended to re-generate emoncms apikey’s and update passwords following this update.

A button to generate new write and read apikey has been added to the My Account section, beware that any devices posting to the account using the apikey will need updating with the latest apikey to continue to work.

To update the account password, hover over the password section and click on the edit icon that appears. Enter the old and new passwords and click save to update.

This security fix and recommendation to generate new apikeys and update passwords applies to both emonPi/base systems and emoncms.org

Serial Monitor

Emoncms now includes an in-built serial monitor feature, useful for configuring connected hardware, including setting calibration values, nodeid’s and debugging issues. The serial monitor can be found in the Admin sidebar:

Extended firmware updater

A couple of minor improvements this morning (v10.7.2):

  • Fixed a bug that showed up in the serial monitor when using emoncms-docker
  • Emoncms update and general log view’s now redirect to the login page if the session times out
  • Buttons to start, stop, restart, disable and enable services are now shown next to the service list on the admin page.
  • Reintroduced retry mechanism in the firmware upload script for more reliable ‘firstbootupdate’ results.

A screenshot of the buttons to control the services:

Emoncms.org has now been updated fully to version 10.7.4, including the new menu system, colour scheme selector and latest version of the dashboard and apps module.
