Oh, sorry, I obviously didn't read fully and thought you were talking about the new drybox stuff, since Valery was sending me drybox emails at the same time. Anyway, yes, everything seems fine and updating to me.

Since I'm still not really sure what you are saying is wrong besides the two-decimal place value not changing on the CSS screen, I just went a head and reduced the MDEL field for the EP temperatures to 0 so any change, no matter how small, is displayed in EPICS.
Please note that this is different than the MyaArchiver deadband, that has not changed.</div>

The MDEL field was implemented by Nathan some time ago to limit network traffic for those PVs. We already lowered them once a few months ago but now they are set to zero.</div>

Attached is a screenshot of a live view of MyaPlot showing that the temperature sensors are indeed updating in EPICS. Note that there are some PVs, like Temperature 10, 11, 13, and 14 who are still not changing more than 0.01 deg C. These indicators will still
look like they are frozen on the CSS screen since their change is below the indicator's precision.<br class="">

Yes, the sensors in the N2 volume and EP are the same hardware and they have always behaved differently in terms of their reading because they are in different regions of the RICH.</div>
