Great to see this was added to the WebApp, even though it looks a bit too verbose/cluttered IMO!
Suggestions::
Omit units like Temperature/Humidity/Power" completely. The sensor is known, and seeing ON/W/°C/mbar is usually enough of a clue to know what the numbers mean. Or use “T/H/P” for common metrics
Add “Last Alert” time to sensors that support it (x minutes ago)
Remove battery indicator (al least if it’s OK)
Allow users to select which fields should be displayed
And obviously all this WebApp goodness also needs to be ported to the mobile App as well…
