Dashboard crashes when adding gauge

[dylandn]

Mycodo 8.2.2
If I add a Guage widget and set the measurement to any value from a PID controller, the dashboard crashes with this error. Adding a Gauge widget and setting measurement to a sensor input works fine, there's something breaky with PId controller .

Error (Full Traceback):

Thanks for the bug reports. I pushed fixes for both of them. Can you upgrade to master and test that they are both working? Since your dashboard(s) are in a messed up state, first delete all dashboards from the diagnostic page, then go to the default dashboard that is created after the dashboards are deleted, and try adding a gauge.

All fixed up, thank you!
