I like the test in the link you posted :)
Also suggest that your sensor is working.

Not sure what sketch you are using, but it will have a event loop.

If you look for where the text is printed, it might have a sleep(2) or 2000 just as the last function.

Not sure if it's a little too sensitive.
Mine shows 100% when it's raining. However if the sensor is wet, then it will have to dry off for a few days.

Im not sure if there is a better more tolerating sensor out there.

I will see if i can print some slits to cower the openings with. To avoid the sensor getting wet.

Hi.

I use Celestron AVX with Orion SSAG. Not sure if it is camera or mount that is the biggest issue.

I guide with QHY CCD Via Celestron GPS with Use pulse CMD = OFF.

I have to disable two axis calibration. When guiding starts it does guide in two axies, but uses a minute or two to settle down.

Hope this is helpfull :)

@gonzo Good thing you fixed it. I have not really changed anything on the webapp. Only the config and start, stop script. My pressure sensor is also a little off (mine is to high). I'll try your approach to calibrate it :)

@kalda. If you worry about moisture on the IR sensor, it looks like you could just glue on that dome. However I have not notized any difference from the sensor with or without raindrops on it.

Hi kalda, thanks for the heads up.

Jasem has now moved the totorial to indilib.org/support/tutorials.html and added a link on the fron page :)

Hi kalda.

The new article is already published to indilib.org/develop/tutorials/177-howto-...no-meteostation.html

Hope you find it usefull :)

Hi Jasem. Looks like I was depending too mutch on the autogenerated html from the converter.

I have now removed the wanky TOC and fixed the h3, h4 issues, added the autotoc class.
I also split the HOWTO into 4 pages, and added the readmore tag.

Hopefully good to go now. (or is it? let me know)

I also edited the author alias for the DIY: INDI Telescope Cover artcle (so it matches).

Jasem, I just added the full howto as html to the subbmit article page.

If anyone like to know a good way of converting markdown to html, then this page is the best bet. dillinger.io/
Select Export as > Styled html, and you are good to go :)

My meteostation dropped out after a full on rain storm a few nights ago. Could be something random, but i'll have to visit the observatory and inspect.
Hopefully a easy fix.

So all my updates was merged into Indi master 6 days ago, so no need to clone my fork of indilib and change between branches anymore.

So here's the first week of weather data :)



Looks like my corrected sky temp is -18 for clear skies, and +7.75 for 100% clouds, so I'll have to update that in my firmware.

As to the pressure graph. Even thoug only 1.0k is marked, the graph shows values from 986 - 1036 (like thae gauge. Would be nice to show that more clearly, but over a week there is visible variations. I might have to calibrate the sensor some, as it went off the chart for a while.

That's a bummer!
It should be changed anyways, as i=++1 is no good, but do not know what it does.

In the pressure graph you removed the average line.
Is this a calculated line, that will change over time, or just a fixed value?

If you look at the graph over a week, could it be usefull to see the average?
If the weather is unstable with many local pressure variations, it could be nice to see if the average is high or low?
Just asking as I don't know a lot about meteorology.

Magnus replied to the topic 'Building the induino MeteoStation with 3d printed housing' in the forum. 3 months ago

Looks like you are getting closer.

I have not modified any of it. In meteostationWEB, I have only modified meteoconfig.py, and [stop,start]METEO.sh
Have you tried changing the i=i++1 to i += 1? and if so, then no MinMax fail?

Code a update to set the graph Y to 850 - 1100, and good to go? :cheer:

So.. i googled it.

1 hPa = 1mbar (think dht22 is mbar)

On this screenshot from the meteostation graphs
raw.githubusercontent.com/magnue/induino...-meteoweb_graphs.png

You can see that 1/3 up on the graph is 1k (1000), so I googled a little.

From en.wikipedia.org/wiki/Atmospheric_pressure (scroll down to Records)

The highest adjusted-to-sea level barometric pressure ever recorded on Earth (above 750 meters) was 1085.7 hPa
and
The lowest non-tornadic atmospheric pressure ever measured was 870 hPa

So if the scale of the graph is 0 - 3000, and the actual variation is 870 - 1085.7, then there is not much variation to see!
The line drawn would never use more than ~7.5% of the height of the graph.

Hm, not sure what you could cange.

The presure changes very slovly over time. If you have the meteostation up for the full graph time of tree monts, you should se some changes.

One thing is that the presure stays close to 1000. If the graph is 0 - 1100, then flux between 900 and 1100 shows as small variations.

You coul probably google minimum and maximum outside air pressure ever mesured, then adjust the min / max in the graph accordingly.

A graph shoving values from 800 - 1200, would give a more interesting graph. (800 - 1200, or something, just guessing numbers.)

Magnus replied to the topic 'Building the induino MeteoStation with 3d printed housing' in the forum. 3 months ago

Yes, that's correct.
I saw it after the last post and googled it.

i++ is not valid in python
i=i++1 is not valid syntax in any programming language

It should be
i += 1

I'm not sure how this happened, but the i=i++1 has been in the code for the last five years, so this part of the code has never worked....
