Interested to see if [[IGN-13789] [null, Bad\_NotConnected("Communication with the data source is defined, but not established, and there is no last known value available."), - #13 by Cody\_Morgan](https://forum.inductiveautomation.com/t/ign-13789-null-bad-notconnected-communication-with-the-data-source-is-defined-but-not-established-and-there-is-no-last-known-value-available/109125/13) is related, there seems to be some fun in the firmware revisions.
