Air Quality Monitor

Yes, as described here.

Costing me about 5,000 points a day for 30 calls from PWS_dashboard, since I changed API call frequency from 2 minutes to 30. OK, that’s about $10 for 200 days, but data displayed is almost as stale as the official WAQI site.

I note that the PurpleAir Flex (outdoor) and Zen (indoor) models have replaceable sensors at $25 the pair. . . But I’m not really interested in their experimental VOC readings.

Plus an initial 25% deposit. . . It is unclear to me when/if this is refunded: maybe when/if you decide you don’t want another one?

It looks like I’m not going to get my Nettigo device any time soon. It was transported from Poland through Germany to Coventry in the UK. It then disappeared from the tracking system for a few days. It’s reappeared today saying that it’s being returned to sender. Haven’t a clue why and there’s no detail in the tracking system. I’ll have to wait until it gets back to Nettigo to see if they can figure out why it’s gone on a two week round trip tour of Europe.

My Gaia A12 arrived this morning - with a US power adaptor :roll_eyes:

Gaia says: "Yes, I need to apologise for that, this is indeed a US USB power adapter.
That’s something we absolutely need to fix since we only have US and EU power adapters now :frowning: "

Any further forward?

It’s not arrived back in Poland yet. Nettigo have asked DHL why it’s being returned but haven’t had a response yet.

Hi, yes I think that option is a sort of loan for use and the security deposit will surely be returned when you decide not to renew the loan and especially when you return the I think, otherwise that 25%are held.

It seems that DHL can’t track things within their own network so my kit is lost somewhere in Europe, having actually made it as far as the UK at one point.

Nettigo are going to send me another kit using a different company who will hopefully be more successful at actually providing a delivery service.

It took a while but the replacement Nettigo air quality sensor kit fnially got here by UPS. I’ll build it when I get a chance but I’m stacking lots of things up at the moment so it might be a couple of weeks before I have it working.

My Gaia A12 arrived 15 September and I still haven’t installed it. . . :wink:

Wow BOS you have a Gaia A12.
I was looking at one of those a while ago, would like to know when you have got it working and the results

I started to build whilst waiting for a test GFS run to process…

Looks very nice indeed

It’s only been working four days… . . The private dashboard gives a huge amount of info for the three sensors individually, but the API does not - yet. However, because you use the same API key as PWS Dashboard it is possible to modify PWS_load_files.php to display your own data in AQ_gov_c_block :slightly_smiling_face:

I didn’t reformat the title or the left text block, which should say “Swanston Grove”, or delete the distance of my official station - just wanted to prove it was possible. Popup data is a bit thin on the ground. . .

(I know this topic should be about Home Built kit but the OP did mention he was looking at Gaia A12.)

I’ve just finished off the Nettigo build (after I found my glue gun). It’s only been running 30 minutes so I don’t have a lot of experience of it yet. It seems simple enough to configure/operate.

This is the current data (local) web page:

It also uploads data by default to a Grafana site which I assume has been set up by Nettigo. You can get graphs for various periods there, e.g.

There are also other data upload options but I’ve not investigated those yet because I don’t have accounts on the relevant services and I need to look into who provides the service and what happens to the data.

Thanks for that info looks good and you seem to do the same as me and modify the blocks to get rhe info that you want.
Wim doesn’t like that at all.
I’m now waiting for the new dashboard to download as I will need to modify
I always look at your site a few times a week.

The Nettigo Air Monitor can interface with the following ‘services’:

  • Sensor.Community (I believe this is what used to be luftdaten.info?)
  • madavi.de
  • aqi.eco
  • InfluxDB
  • OpenSense Map
  • Feinstaub App
  • Your own API
  • CSV output

Mine is currently connected to Sensor.Community (although I don’t see my data there yet), madavi.de and aqi.eco. I don’t know any of the other service destinations so I don’t know how useful they are.

Edit: The Own API sends JSON data, e.g.

"software_version": "NAMF-2020-45",

I’ve registered the sensor on community.sensors, although it took a Google search to locate the registration page. Not sure why it doesn’t seem to be linked to on the main pages. My data is being seen but I guess it takes a while before my station appears on the map.

Edit 2: My sensor is on the map, but it’s currently an indoor sensor so not shown unless you select to display indoor sensors. I need to work out where I can locate the sensor outdoors where there’s somewhere to get power nearby.
