I know this is a Node-Red forum but many on here use Grafana.
With 8.0 there is now live streaming in graphs and support for Booleans.
From an IoT & NR perspective you can live stream to Grafana via MQTT.
With 8.1 a new Action panel somewhat akin to NR Dashboard panels will allow both status update and Actions sent from the Panel to NR via MQTT/other. 8.1 Action panels will support SVG elements/toggles/sliders etc.
v8.1 hopefully will ship in around 6 weeks time the MQTT data source plugin is not currently instable from within Grafana but from Git.
Attached is a screen shot form todays IoT day Grafana have taken the first on many steps to support comprehensive IoT dashboards.
@tve there are other features coming like industrial automation like Alarm panel. A free format graphics editor panel so you can do floorplans/SCADA mimic/BMS headends, with drag & drop placement of realtime metrics. These developments have been dependant on changes to panel plugin & v8 backend and a new team of three who are called Grafana Edge.
