I can bring that back. I was probably a bit over zealous on the formatting!
Rain needs three decimal places.

That’s true for inches. For centimetres there should only be 2 decimal places, and for millimetres only 1 decimal place. More than that and I think you are probably implying an accuracy greater than what the sensor is capable of (+/- 0.2 mm/hr).
Here is a sample of the UDP data from the Hub. It’s to 6 decimal places. This is one munute readings in millimeters.
Yikes! That I did not expect. Surely the SKY cannot resolve a micro-meter (10^-6) of rainfall in one minute?
Edit: I guess it maybe that no rounding is done to the raw rain accumulation value that is calculated by the SKY/Hub and output via UDP or sent to the WF servers. I assume once it reaches the servers they round it appropriately for the accuracy of the instrument before displaying it on the app/web page or sending it back out via websocket or API. Perhaps @dsj can comment?
Yes, the haptic sensor can detect very tiny amounts of vibration that translate to very tiny amounts of rain. Just remember: precision and accuracy are two different things!
We do not round it on the server side, since it can be useful for unit conversion and derived parameters to keep the original precision (even though 0.000001 mm is rather ridiculous). However, the precision is limited by our apps, which round to 0.01 inches or 0.1 mm. This results in the apps displaying some non-zero rain as “0.00 inches” or “0.0 mm”, but that’s pretty rare. We will likely add a qualitative label like “trace” in future builds.

I’m precisely inaccurate at times.
I’m dealing with that exact item this morning.

Impressive! Turns out the sensor is even better than I thought then.
I think with the PiConsole I am going to follow the same convention as on the apps, just curtailing the decimal places as needed if space becomes limited (the screen after all is quite tight on space). “trace” is an interesting idea for small amounts of rain. What would be the absolute minimum rain accumulation that could be distinguished from zero?
The minimum would be 0.000001 mm but I seriously doubt we would ever see that reported. I am using
rain > 0 and rain < 0.001 = “Trace” for inches.
mm would be .1

I’m trying to find where the Version # information is stored? I upgraded a few days back, and I’m not sure if I got ver 1.4 or 1.5 ??
can anyone HELP?

Hi @eric, I’m struggling to recreate this error even if I use your station number in the .ini file. The error comes from the METAR API call in the Sager forecast routine, and I imagine it might be happening because the API call is not returning a complete METAR report. Can you try running the code again and let me know what happens? I think there might have been a server issue this morning that was bricking the API call and hence the console. I should add some code to make sure the console can survive the API call failing!
just tested it again, no more errors so that seems indeed a remote problem. Guess you need to add a control routine to intercept the error and just set zero values instead a crash

Thanks –
OH well. I overwrite that file (with my previous version) before even running!
Peter:
I just updated to version 1.6 and can’t seem to get it up and running … I do get a Kivy screen up but get the following log.
EDIT: this installation was installed in a different path - my previous version (unknown ver 1.?) is still working fine.
