  • Based on Debian Raspbian Stretch minimal

  • Compatible with Raspberry Pi 3 & 3B+ (minor change required for Pi2*)

  • No longer use read-only root file system

  • Emoncms data is logged to low-write ext2 partition mounted in ~/data

  • Log partition /var/log mounted as tmpfs, non-persistent between boots

  • SSH access disabled by default, long press emonPi LCD push button for 5s to enable. Or create file /boot/ssh in FAT partition.

  • OpenHAB & NodeRED removed, can easily be installed via apt-get

* To use this image on Pi2 remove the following lines from /boot/config.txt :

arm_freq=1200
arm_freq_min=600

Known Issues

  • Current bug in rpi-gpio 0.6.4 causes LCD push button to stop working, a solution is to continue using 0.6.3 pip install RPi.GPIO==0.6.3. Open issue.

  • Mosquitto 1.4.10 is included in this release, this is a downgrade from 1.4.14 included in the previous image (emonSD-26Oct17). This is because 1.4.10 is the current stable Stretch apt release. A newer version can be manually installed if required https://mosquitto.org/download/

New changes compared with previous release, SD-card-build.md has been updated:

  • Based on Debian Raspbian Jessie minimal, updated to latest packages, kernel and firmware. Includes patch for KRACK WPA vulnerability:

  • Compatible with Raspberry Pi 2/3 (not zero or 3B+)

  • Automatic NTP time update: see forum thread and changes.

  • Fix random seed: improved HTTPS / SSH security. See forum thread.

  • Use dtoverlay=pi3-miniuart-bt instead of dtoverlay=pi3-disable-bt in /boot/config.txt This re-maps RasPi3 bluetooth to software serial/dev/ttyS0 instead of disabling it.

New Changes forum discussion

  • Append gpu_mem=16 to /boot/config.txt to give us more RAM at expense of GPU

  • Symlink fstab in emonpi repo to /etc/fstab to allow updating

  • Reduce garbage in /var/log/messages but to Raspbian bug

  • Fix log rotate to includue all log files to ensure /var/log does not fill up

  • RasPi3 SSHD fix

  • Fix language pack support (install gettext & locales), language setting in ‘Account’ now works out the box

  • Fix node-RED flows to survive update cycle

  • Trim SD card (allow 60mB of unallocated partition) to fit on all (or majority) of 4GB SD cards, shop pre-built SD cards included with emonPi / emonBase will be 8GB with ~/data partition expanded accordingly.

  • Generate new SSH keys

Writing the image to an SD card

Option 1: We recommend using balenaEtcher to flash the image to an SD card. See forum discussion.

Option 2: Use the Raspberry Pi Imager. Select ‘Use custom: Select a custom.img from your computer’ and then select the emonSD image that you have just downloaded. There is no need to unzip the image first, just use the .zip file directly. WARNING: the user name must not be changed; it must be “pi”.

Before bootup SSH & WiFi configuration

Before booting up the Raspberry Pi you may want to enable SSH and pre-configure your WiFi details on the image first. SSH provides command line access to the RaspberryPi. If you are not sure if you need this, leave it disabled for now, it can be enabled later.

Plug the SD card into your computer again and wait for the SD card partitions to load. On Linux you should see three partitions: boot, rootfs and a larger data volume. On Windows you may only see the boot partition.

To enable SSH: Open the boot partition and add an empty file called ssh.

To configure WiFi: add a file called wpa_supplicant.conf to the boot folder. Add the following template and replace the <> parts with your WiFi details:

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=<Insert 2 letter ISO 3166-1 country code here>

network={
  ssid="<Name of your wireless LAN>"
  psk="<Password for your wireless LAN>"
}

Safely dismount the SD card and insert in the Raspberry Pi.

First boot update: If connected to the internet by Ethernet (or pre-configured WiFi), a fresh emonSD will run a full system update. It’s best not to interrupt this process. Leave about 10 min before switching off or rebooting. See /var/log/emoncms/update.log if you want to view the update log to check if it’s finished.

WiFi Access Point: If the SD card is booted without ethernet connected or WiFi configured it will create a WiFi access point (emonSD-10Nov22 SSID: emonSD, Password: emonsd2022) to allow scanning for a local network and configuration via the web user interface IP address: 192.168.42.1. The first boot update is not performed in this case and we suggest updating via the emoncms admin interfacer at a convenient time once the system is up and running.

Identify Image Version

The Image version can be identified in three ways:

emonPi systems: - View emonPi LCD at startup or press the LCD button the scroll through the pages until emonSD-XX is displayed.

All systems: Emoncms admin interface - view the emonSD version in the local Emoncms admin interface.

All systems: Look for a file in /boot partition for a file called emonSD-XXX in the FAT /boot partition:

$ sudo ls /boot | grep emonSD
