I'm trying to find a dashboard which:
- Has pretty widgets for data display
- Can subscribe to, and display MQTT data that I publish
- Can publish commands to subscribers (eg: "Driveway light switch: turn on")
- Is free for home / hobby usage
Surprisingly, it's quite hard (for me anyway) to Google for something which fits the bill.
My specific use case: I'm a maker who is trying to remotely measure temperature and control a room's air conditioning system.
