Meteobridge 4.4 (Sep 17 2020, build 13754) on Observer IP PM2.5 Sensor. **solved**

[ice124]

Hi,
I purchased an Ambient Weather PM 2.5 sensor that I'm trying to log with Meteobridge and my Observer IP. I can see the sensor on the Observer IP's webpage:

However, I don't see how to add it to logging on the Meteobridge interface:

Is there somewhere else in the new interface that I need to add the sensor?

The air quality sensor is supported via the GW1000. I recommend adding a GW1000. The GW1000 will pick up all your existing Ambient sensors. The Meteobridge is compatible with the GW1000 with a much more reliable data connection method than using the ObserverIP.

Adding sensor on calibration screen just adds calibration options for existing sensors. You cannot define new sensors there. This is a funny try

Currently the ObserverIP implementation is not supporting air quality sensors. To add this I will need remote access to a Meteobridge that has one connected. If you want to grant me remote access, please read the FAQ how to setup and send URL and password to info(at)meteobridge.com.

I'm confused... there is a post from the Meteobridge 4.0 release notes stating that the PM2.5 sensor is supported. Has there been a feature regression?

released May 22, 2019

adds support for air quality sensor PM2.5 for Ambient Weather Observer-IP. PM2.5 data is reported as template variable "air0pm" and is displayed on "Live Data" tab.
adds support for air quality reporting to weather underground and ambientweather network.

You assume that I can remember that much detail for over a year

I will look into the code. However, I can't test as I don't have that equipment here und the login you provided does not work.

P.S.: I can confirm that it is in the code. Meteobridge's observerip module is just doing screen scraping of the web page you pictured, as observerip is not providing a proper api to get data from. If they change something by a newer firmware (to make it look nicer, for example) the Meteobridge capture code will not recognize it anymore, what is my guess about what has happened here.

When I don't get remote login, then just sending me the HTML code of the page you pictured above might already bring light into the scene. Meteobridge currently looks for a string "pm25" to sync.

I've uploaded the LiveData.html file here:
Raw HTML: https://ln.sync.com/dl/d15ce4a40/xgab9g ... d-n4uqg2gv
Integrated MHTML (images, JS, etc): https://ln.sync.com/dl/e5dbabf00/zpn55f ... x-iu77zvbn

Hopefully this will help adjust your parsing script. I believe that they added a second PM2.5 (indoor) in the most recent release of the Observer IP firmware. Maybe that is causing this issue?

Thanks, it is as expected. They invented new names "pm25in" and "pm25out"

Code: Select all

<tr> <td bgcolor="#EDEFEF"><div class="item_1">Outdoor PM2.5</div></td> <td bgcolor="#EDEFEF"><input name="pm25out" disabled="disabled" type="text" class="item_2" style="WIDTH: 80px" value="6.0" maxlength="8" /></td> </tr> <tr> <td bgcolor="#EDEFEF"><div class="item_1">Indoor PM2.5</div></td> <td bgcolor="#EDEFEF"><input name="pm25in" disabled="disabled" type="text" class="item_2" style="WIDTH: 80px" value="0.0" maxlength="8" /></td> 

Please try just released update.

We're getting closer. I can see the fields now, but I'm getting 0's for the value. Perhaps a value field parsing issue?
I'm currently only using the "pm25out" device, which in the Observer IP's interface reports currently as a value of 6.0. Meteobridge "Raw Sensor Data" tab is reporting 0.0 for both "Air" and "Air #1".

Did this ever get resolved? I'm interested in purchasing one of these air quality sensors. Topic shows solved but can’t be certain based on the last post. Sorry...

[admin]

yes, as you can see from release notes: https://www.meteobridge.com/wiki/index.php/Forum

released September 19/20, 2020
- adds support for ObserverIP's new firmware that reports air quality for indoor (air0pm) and outdoor (air1pm) sensors.
