Thanks Brian,
Have run a test and it’s not quite right.
The only other box ticked is “Enabled” The number 2455820 I entered is the local sensor number but the same result occurs whether the box is populated or not.
To double check the sensor was working, I accessed the sensor via a browser using that IP and was able to get in to the interface just fine.
As per Wim I entered http://api.luftdaten.info/v1/sensor/14396/ in the IP address field (where 14396 is my Luftdaten sensor ID) and then clicked “test”. This didn’t produce an error message but only returned “Values” and “0.0” respectively.
Hope that helps
Cheers
Nick
Hi
I was not meaning you to enter a sensor ID
just the local IP
as the format
IP /data.json
as per what wvdkuil had provided already
do that and then post here the airquality2.txt file after clicking on test
Ah ok Brian, very sorry I’m not very technical so missed that.
I’ve done that and I get an error message “152: No server specified in URL”
There is just one line in airquality2.txt and it reads
{“mapVersion”:“0.70”,“baseVersion”:“6”,“mapVersionString”:“”,“results”:[]}
I have attached a screen print of my settings just in case I have misunderstood again
Cheers
Nick
try adding http://
to the start off the IP address
Ah, that sort of worked. No error message appears
airquality2.txt now has:
{“software_version”: “NRZ-2018-111”, “age”:“80”, “sensordatavalues”:[{“value_type”:“SDS_P1”,“value”:“17.67”},{“value_type”:“SDS_P2”,“value”:“13.90”},{“value_type”:“samples”,“value”:“634677”},{“value_type”:“min_micro”,“value”:“225”},{“value_type”:“max_micro”,“value”:“26883”},{“value_type”:“signal”,“value”:“-83”}]}
The particle value shown on screen is odd (see attached screen grab)but only looks like it’s picking up the wrong field. The P2 data in airquality2.txt matches the current value in the sensor.
Oh wow, that worked.
Airquality2.txt reads:
{“software_version”: “NRZ-2018-111”, “age”:“0”, “sensordatavalues”:[{“value_type”:“SDS_P1”,“value”:“57.47”},{“value_type”:“SDS_P2”,“value”:“28.70”},{“value_type”:“samples”,“value”:“636748”},{“value_type”:“min_micro”,“value”:“225”},{“value_type”:“max_micro”,“value”:“26692”},{“value_type”:“signal”,“value”:“-82”}]}
The WD setup screen reads pm2.5 as 28.7 (see attached)
The sensor reads the same (see attached)
Thanks a lot Brian, does that mean it’s good to go?
yes, hopefully now WD should be running the cronairquality.exe program every minute and updating the data auto now
for PM2 and the calculated AQI
for now at least
I could add in to get PM1
The cron seems to be running but this pops up (see attached)?
It doesn’t seem to relate to the Luftdaten sensor details.
download a new .zip test program update, same url as before
new WD version (PM1 should work now) and new cronairquality version…should work now
Hi Brian,
I’ve done that and the cron seems to be running as the airquality2.txt changes it’s time every minute and the data seems to change too.
Nothing else seems to be happening, so I’ll leave it to run over night and see what the morning shows on the main graph.
If I go into the purpleair icon in “View” I don’t see the correct readings? (see attached)
My sensor only does PM10 and PM2.5 so don’t think I can test PM1
Cheers
Nick
Hi again Brian,
The aqi charts are being produced but are straight lining at zero and I would have imagined the first readings would have shown by now. As I said, I’ll leave overnight and see in the morning
Thanks again for doing this
Cheers
Nick
I have fixed a few more things up,hopefully
download another .zip test version update, ready now, same url
Thanks Brian, I have done that and it’s been running for a while now.
The aqi graphs in webfiles aren’t being produced although the aqi plot on the main screen graph has received just one plot, there isn’t a scale showing.
I’ve attached the aqi screen grab from the view menu, it now reads zero and has one plot shown
Cheers
Nick
download again…as before
should be much better now #-o
Ah ha! View menu screen shows correct PM2 reading now and an AQI level, the main screen graph now shows the AQI and it is being plotted (see attached). I will need to investigate how AQI is being calculated so can’t vouch for that but will assume correct as PM2.5 is correct.
The AQI charts are being updated in the webfiles folder but don’t seem to change their timestamp, properties shows to have been modified rather than rewritten so I assume that is normal?
I’m off to bed now but will check again first thing, it certainly looks ok
Thanks Brian
Cheers
Nick
forgot to say PM10 looks like it is being correctly recorded too
Hi Brian,
Been running 12 hours now and seems fine as far as I can see. Sensor readings and graphs seem fine. This is a quick and dirty web page using the WD gifs https://www.sunwharf.com/willingdon/aq.html
I’d like to create a rolling 30day graph, which log file has the data in please?
Thank you very much, lovely job
Cheers
Nick
you can create custom log files with WD using custom tags
