Just a small note to indicate that on last snapshot, the profile timestamp-update is available :
DateTime Sun_Azimuth_LUD "Azimuth LUD [%1$tH:%1$tM]" <time> (gSun, gSensorTST) {channel="astro:sun:home:position#azimuth" [profile="timestamp-update"]}
will update Sun_Azimuth_LUD item to ‘now’ each time the linked channel updates.
The same principle applies with profile timestamp-change.
