emonSD pre built SD card Download & Change Log

Glyn Hudson edited this page Nov 8, 2018 · 94 revisions

EmonSD is a pre-built SD card for Raspberry Pi running as an emonPi / emonBase.

Identify Image Version

The Image version can be identified in three ways:

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

2. Emoncms admin interface - view the emonSD version in the local Emoncms admin interface.

3. Look for a file in /boot partition - Requires SSH access or put the SD card into another computer. Look for a file called emonSD-XXX in the FAT /boot partition:

$ sudo ls /boot | grep emonSD

All emonSD images have:

  • Read-only root file system
  • 4GB min SD card size, 8GB recommended (shop bought emonSD cards are expanded to 8GB)
  • Latest images have been built using emonPi SD card build guide

a.) Purchase pre-built SD card

or

b.) Download image & flash to SD card:

Important: on the first ever boot of a fresh emonSD the system will run some automatic updates to update Emoncms and emonPi firmware, it's very important this process is not interrupted. On first boot please ensure an Internet connection (Ethernet ideally) and then leave the system for at least 10min before switched or rebooting. See ~/data/emonpiupdate.log if you want to view the update log to check if it's finished. This step does not apply to fully assembled units purchased from the shop.

  • Expand data partition to fill SD card:
  • By default the 'data' partition used to store Emoncms data is 1GB, this can be expanded to fill the remaining space on the SD card. This has already been done on shop bought emonPi / emonBase. To expand the data partition:
  • Connect via SSH and run $ sudo emonSDexpand and then follow prompts.

  • 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

  • Raspbian Stretch
  • Compatible with RasPi 3B+ (and backward compatible with older RasPi)
  • Raspbian Stretch upgrade build notes
  • Important note: RasPi 3B+ requires 2A min (2.5A recommended USB 5V PSU) with 20 AWG power cable. Ideally not longer than 1m in order to provide sufficient power. WiFi may be unstable (especially WiFi AP hotspot) if the voltage is low. The red LED on the RasPi should be lit up continuously to indicate sufficient voltage. All emonPi/emonBase units brought from the OpenEnergyMonitor shop will be shipped with the correct PSU & cable.
