Help getting started

[ESteg]

Received my 2 monitors yesterday (shipping to the Netherlands). After connecting the monitor that's based on the 1102 sensor, I could update the WiFi settings and the latest firmware was automatically updated. Very smooth! I did have some issues though getting the monitor to update values to ThingSpeak.

When I tried the other monitor, with the 7160 sensor (+ temp/hum/press), it immediately started to update all 4 values to ThingSpeak (with a different API, of course).

Here's a dump of the output after connecting the 1102 monitor: I'm not an expert on this, do you notice anything that explains why this monitor won't show the "Raw CO2" values like the 7160 monitor?

Many thanks!
Etienne

Hi Etienne,


I am glad that it seems to be working well.
The raw CO2 is rather a debug message that has to go away.
In general the CDM reads CO2, but it takes a minute until some internal averaging logic kicks in, and until then - the raw CO2 value is not taken int account (but i dumped it for debugging)
the CM1102 sensor works in a way that in the first 2 minutes it reports 550 ppm (i do not know why they choose this value ) ), and then it starts to report the correct values.

What were your issues with TS? I am currently reworking the configuration tool and writing (finally) some docs, so i could add this details there

Regards, Vladimir

Hi Vladimir,

The CDM-based monitor works perfectly: it uploads the values to TS after I entered the API in the configuration tool.
The CM1102-based monitor does not upload any values though, after configuring it in the same way as the CDM (but of course with a different API). It's connected to the WiFi using the configuration tool (confirmed the connection on my router), but on the TS site it shows 0 values were received.

Does the code I pasted in my 1st post from the CM1102 look OK?
Thank you very much!

Regards,
Etienne

ahhh i saw in the log that the reqeust to TS is being done but i did not understand that you do not get anything...
if you try to invoke the same url from a browser - does it work ?
try to send a command (from the input field at the bottom)
debug
it will the dump a bit more details, and especially the response from TS, it is the number of entries in the channel

OK. I have my gadget (a CDM 7160), but I seem to be missing the 'basic info' page. There was nothing in the parcel with a clue. I found this website/forum with a bit of duckduckgoing.

Plugging into USB gives me

[710364.564061] usb 4-1: new full-speed USB device number 16 using uhci_hcd

[710366.263793] usb 4-1: ch341-uart converter now attached to ttyUSB0

And I can connect with screen but I don't know what speed I should be using. Does it say somewhere? At 115200 I see nothing, but no wrong-speed garbage either. Is the protocol documented somewhere?

If I press the button a green LED shows whilst it is held. Still nothing on serial port.

Where is the 'how to use you gadget' page? I did look around the http://vair-monitor.com site and found out about vesprino, but nothing on how to use the vair-monitor. control methods, data out methods, power (does it have a battery, does it need to be USB-powered permanently? - I assume yes), what do the LED colours mean (it was faint purple when I first powered it up).

Clues welcome.

I am sorry for the confusion, and that you needed to spend so much time searching this.
It is true that i am a bit lagging with documentation. 
If you go to http://vair-monitor.com/ - there is a big blue button [Setup Instructions] - that leads to this page: http://vair-monitor.com/device-types/
With details about driver installation (in case you need them) and the Chrome app used to setup the device.

I assume your "Internal Spam Filter" that protect you from this typical page template has filtered it out : will think how i can improve it to avoid confusion, maybe i can also add a button on the top right as well.

About the LED and colors - they are still to be defined (there is one forum topic to discuss ideas about it (linked from the page above))
About the power - it has to be powered with 5V usb, there is no battery in this model

If you have other problems - do not hesitate to ask

[Wookey]

Cheers for the quick response.
I did see that but I kind of ignored it as I don't use Chrome. Hadn't realised it was the only way to configure things.
Seems to work fine with Chromium.
And via that I discover: https://github.com/vlast3k/simple-co2-monitor-fw and https://github.com/vlast3k/vESPrino which seems to contain useful info.

Anyway my gadget seems to work, so I'll sort out getting HTTP or MQTT working

[admin]

Great
Yeah.. i dream about the time when i will have sorted out all the initial startup glitches and consolidate all information on one place
