I am going to open up the USB cable to measure the current flow with a Fluke 287. I’ll either get a true reading or I’ll blow up a power supply and maybe the Hub. What could possible go wrong?

Nothing was changed in database by me. database and files are up to date (latest version). Any idea what is happening?

I measured with my powerbank and that reads 0.1 A at 5.01 V (current goes only in 0.1 A units, so it can be anywhere between 0.05 and 0.15 A, assuming it rounds correctly)

I have no idea. Try running AlterTables.
I tried already, also tried to run repairtable.js but result is same. What kind of column is NaN? I will add it manualy.

NaN is not a field in any table. It’s an error meaning Not a Number.
Something else is happening to cause that error.
For last two days in DailyAir below field are empty: TempHD, TempLD, PressHD, PressLD and all fields right from PressLD. Does this saying something usefull?

Run UpdateFiles from the About tab. I added some new error output in dailystats.js that should show the error.
You can manually run dailystats from a terminal window and then look at the log file to see the output.

For some strange reason, your Humidity High and Low is 0 (zero) which is not possible.
Yes, I just discovered that, started few days ago. Dropping from 90 to 40, then decreasing to 0 over time. Currently humidity reading is 0. Maybe sensor is dead…

Contact support@weatherflow.com about the Air.
I am working on code to catch and correct for the error. Stand-by for new updated files.
New files posted, run Update Files and manually run dailystats.
Ok, thank you Gary. I sent email to support.
