Yes, my little Perl script adds a UTC date field (seconds since epoch) to websocket records as they are read. It understands both eventsocket and logsocket event streams. It's easy to modify the little script to use a different date format.
- Y'all should also add your voice to ask Hubitat to fix the event stream to include time/date stamps.
- Y'all should also ask that the event streams be standardized between eventsocket and Maker API and the on-hub copies that you can download using this awkward URL, which each contain different fields and none of which have a proper date field.
The on-hub download list has an HTML element in it that you can dig the date out of with some work, and the on-hub event listings in the GUI also have dates, but those dates aren't sent out by either of the websocket or Maker API interfaces.
