Installation of snapd
Please refer to official documentation for snapd installation - https://snapcraft.io/docs/installing-snapd
Installation of wmbusmeters Snap
Installing a snap is straightforward:
sudo snap install wmbusmeters
The stable channel is used by default, but opting to install from a edge channel is easily accomplished:
sudo snap install --channel=edge wmbusmeters
In stable channel latest releases of wmbusmeters will be available, but in edge channel wmbusmeters snap will contain all latest code changes.
Using the wmbusmeters Snap
After installing the Snap, the privileged access to USB interfaces need to be configured:
sudo snap connect wmbusmeters:raw-usb core:raw-usb
Using wmbusmeters Daemon
For all actions with wmbusmeters daemon, like enable/disable/start/stop/restart/status systemctl commands should be used
For example:
systemctl start snap.wmbusmeters.wmbusmeters.service
systemctl status snap.wmbusmeters.wmbusmeters.service
Configuration for wmbusmeters
Configuration of wmbusmeters is located in
/var/snap/wmbusmeters/common/etc/
Logs are in
/var/snap/wmbusmeters/common/logs/
When changes are made to configuration, service must be restarted.
Those directories are persistent across updates - files will not be deleted or changed when updating snap. Files and directories are being deleted only when snap is removed.
When using rtlwmbus, rtl433 or shell commands then LD_LIBRARY_PATH and full path to binary inside snap should be used.
In case of rtlwmbus following configuration should be used:
device=rtlwmbus:LD_LIBRARY_PATH=/var/lib/snapd/lib/gl:/var/lib/snapd/lib/gl32:/var/lib/snapd/void:/snap/wmbusmeters/current/lib/x86_64-linux-gnu:/snap/wmbusmeters/current/usr/lib/x86_64-linux-gnu::/snap/wmbusmeters/current/lib:/snap/wmbusmeters/current/usr/lib:/snap/wmbusmeters/current/lib/x86_64-linux-gnu:/snap/wmbusmeters/current/usr/lib/x86_64-linux-gnu /snap/wmbusmeters/current/usr/bin/rtl_sdr -f 868.95M -s 1600000 - 2>/dev/null | /snap/wmbusmeters/current/usr/bin/rtl_wmbus
or rtl433
device=rtl433:LD_LIBRARY_PATH=/var/lib/snapd/lib/gl:/var/lib/snapd/lib/gl32:/var/lib/snapd/void:/snap/wmbusmeters/current/lib/x86_64-linux-gnu:/snap/wmbusmeters/current/usr/lib/x86_64-linux-gnu::/snap/wmbusmeters/current/lib:/snap/wmbusmeters/current/usr/lib:/snap/wmbusmeters/current/lib/x86_64-linux-gnu:/snap/wmbusmeters/current/usr/lib/x86_64-linux-gnu /snap/wmbusmeters/current/usr/bin/rtl_433 -F csv -f 868.95M
or when shell command is being used
shell=LD_LIBRARY_PATH=/var/lib/snapd/lib/gl:/var/lib/snapd/lib/gl32:/var/lib/snapd/void:/snap/wmbusmeters/current/lib/x86_64-linux-gnu:/snap/wmbusmeters/current/usr/lib/x86_64-linux-gnu::/snap/wmbusmeters/current/lib:/snap/wmbusmeters/current/usr/lib:/snap/wmbusmeters/current/lib/x86_64-linux-gnu:/snap/wmbusmeters/current/usr/lib/x86_64-linux-gnu /snap/wmbusmeters/current/usr/bin/mosquitto_pub -h localhost -t water -m '$METER_JSON'
