I had a C# dashboard in my kitchen that I had used for a long time. I have now replaced it with a new version built using JavaScript. It has connectors for Home Assistant, OpenHAB, MQTT, Homematic, Merkio, Google Calendar and email accounts. It can also display video streams and includes a timer, news feeds, and a radio. It is easy to implement more features.
The layout and configuration are completed entirely within the UI; no configuration files need to be edited.
The layout and configuration are completely free and done entirely in the UI, so there are no config files to edit. The backend can run on the same PC or on a NAS or Raspberry Pi. You can also have different layouts for a dashboard at the entrance or in the living room, for example.
