- there is a new settings page accessible from the main dashboard. This allows you to edit your settings directly from the GUI instead of manually in the settings.json5 file. I also added a button on the settings page that allows restarting the gateway app, for such cases where this is useful (ie some settings require this, like changing the serial port). There is not a lot of validation done on the settings page, so edit these mindfully of that. The assumption is that you are not trying to break your own server. Also some settings are not exposed, so they will not show up in the GUI, and some are not editable – these will show but you are not supposed to change them. if you still need to, you can manually change the settings.json5 file any way you want on disk, but keep the formatting/nesting of the objects since that format is assumed in the new gateway app release. Here’s a peek at the new UI:
- I added a new setting called genNodeIfNoMatch (boolean) which can disable new node creation when data is received from a node but no metric is matched to the metrics definition in metrics.js. If you set it to true, a node is added even if no data can be matched to a meaningful metric (node would show in the UI).
- some new metrics/events were added/improved
- logs generated by the gateway app are now rotated and archived with logrotate in a new logs subdirectory (if you manually upgrade you need to mkdir /home/pi/gateway/logs). To facilitate this there is a new /etc/logrotate.d/gateway config file that controls this feature. This means the log is kept under a size and history limit to avoid it growing indefinitely.
- avrdude is now installed on the image so it would support programming MightyHat with a new HEX sketch. Instructions for doing this are on the MightyHat page.
Essentially 4 files have changed: gateway.js, metrics.js, settings.json5, index.html; one file was added: /etc/logrotate.d/gateway. I also posted a MightyHat blueprint DXF case for 1/8″/3mm acrylic (the green areas need to be etched rather than cut).
As always, the image contains pi:raspberry default credentials (change it with passwd) for the main pi login and for the http authentication (make your own .httpasswd file). If you got an ATXRaspi or MightyHat you need to uncomment the line running the shutdowncheck script in /etc/rc.local, to enable power button control. You may also want to create your own secure certificate and setup your wifi. Please let me know if there are any issues or bugs with this release.
