What's new?
System distribution has changed
We changed the base operating system RPi OS Lite of System image from buster to bullseye.
We planned to maintain the Installation package of RPi OS for both buster and bullseye. We are constantly monitoring system changes, but your vigilance will help us update the application quickly.
What does it mean for me?
I'm using system image → It's best to just flash a new image. System image
I'm using installation package on buster → You can update the software as usual. armhf
I'm using installation package on bullseye → Install the package from the following link armhf (bullseye) manually. The default installation package was compiled on the buster system. It's still considered as universal, so it works normally on bullseye but after some time it may stop working if you keep updating your system (because of potential system changes). That's why better to use bullseye-dedicated package on bullseye system.
Features¶
Automatic device time synchronization¶
This option is exclusive for OneMeter Enterprise.
The device time can be synchronized automatically. You should still use mobile application if you want to synchronize the historic data stored in device memory.
Diagnostic data logs¶
This option is exclusive for OneMeter Enterprise.
During synchronization, the gateway can download, parse & log diagnostic data of the device (depending on configuration settings).
Flow control¶
The number of data bytes per device sent to the server has been reduced several times.
For now, the gateway can control the outgoing MQTT packets so as not to forward the same data (already confirmed by the server) multiple times. It is also possible to pass the packets conditionally with a specified period in order to provide a reasonable (not too long) delay of gateway state updated on the cloud.
Remote access option¶
Since now you can enable/disable SSH during network configuration of System image.

Additional system logs¶
Added logs of:
- HCI interface status,
- system signals which do not cause the application to stop.
