vThings - CO2 Monitor for Home Automation

Post by vlast3k » Thursday 03 March 2016 18:18

I would like to bring to your attention a CO2 Meter that i have been developing over the last year. Following my Kickstarter project
My initial goal was that it is cheap and simple to use. Eventually i got in contact with the guys from domoticaforum.eu - here is discussion about it
The guys over there asked me to create a version specially for Home Automation Systems, which has minimal display options, but has an accurate NDIR CO2 Sensor and allows configuring a custom HTTP Server or MQTT server for reporting. As well as configurable interval and minimum threshold of the value to trigger reporting.
The first batch is now out, few improvements have been done for the second revision and now I think i am ready to offer it to more interested people.
There are also options with OLED display and LED bar, and also a cheaper version with a less accurate (+/- 15 %) sensor. In all variants, the enclosure is 3D printed with White PLA @ 0.2mm layer height
You can have a look on the Web Shop i just setup : http://vair.anker-bg.com
The price for the device specially for HA is 60 eur. Shipping is flat @ 4eur per order
I can offer a 5% discount for forum users. If you are interested in this and would like to purchase, you can use VTHINGS_5 coupon code during checkout.
I can also add changes to the firmware based on your requirements (it is open sourced at github)

Has anyone used this with domoticz?

Or has anyone another solution with z-wave or 433? (< 100 Euro).

The device integrates with Domoticz using a "Dummy" device, a "Virtual Sensor" and then configuring the Device to post to a Custom URL in the form:

Code: Select all

http://server:port/json.htm?type=command&param=udevice&nvalue=0&idx=1&svalue=%s
server:port - your http or https port of Domnoticz. If you use user/pass they can be added as http://user:pass@server:port
IDX parameter - this is the IDX id of the device
%s - this is replaced with the actual CO2 PPM Value

In Domoticz you need to create a "Dummy" Device, and then add a "Virtual Sensor" to it of type "Air Quality"

Once the connection is setup, you can configure the Interval and PPM Threshold values on the CO2 monitor - how often to send the data.

(i just added this info also here)

Hi vlast3k,

I'm interested by this sensor for my house.

Your web site seems empty, so is the device is selling again ?

Aaahh am sorry, but apparently i am too fresh on the forum to be able to send private messages :) so i cannot answer you :) I did not knew about this feature
So anyway - some additional details until i bring up the site again (hopefully tonight)

1. Web Site: http://vair-monitor.com/ - just information on the different options
2. With Domoticz you currently need the Wifi option as the device uses serial communication only for configuration. Though if it is possible that Domoticz communicates over the serial port with devices by following some kind of protocol, i will be glad to add it. Just give me some example as i couldn't find such easily in the docs...
3. The battery option - it turned out that i cannot sent batteries via the standard post, so i am not offering it anymore. But the device consumes 70-100 mAh. So you can connect it to an usb power bank
4. The plain option is with Leds. And the price with Wifi and the NDIR sensor is 70 eur, with the less accurate sensor it is 55 eur. Shipping is 4 eur (to add an OLED display is +10 eur)

Is there plans to do a Carbon Monoxide version of the monitor?
Now setup on a RPI3.
Also using Evohome HGI80, RFXTRX433E and a Aeotec Gen5 stick. Mainly a Gen5 Z-Wave system.
My weather (Davis vantage Pro2) data is obtained by weatherunderground
Now collecting rtl_433 data from Apollo Ultrasonic meter

In general i plan to create various kinds of sensors and CO is one of them.
But i was with the impression that CO monitoring is a commodity already and there are various sensors available?
(but we have central heating and no open fires so i havn't dig to deep in this topic to be honest)
Can you elaborate what is missing? Connectivity to a Domoticz etc.. or ?

Hi,

On the web site for this model (plain with leds) the wifi option at 10€ brings the sensor at 80 euros, isn't it ?

Are you trying the vAir - CO2 Monitor - this one http://shop.vair-monitor.com/index.php? ... uct_id=123

and check if you are not adding some extra space before it
APRIL_VAIR
it should display a green panel:
Success: Your coupon discount has been applied!

You state :

Thnx, received the sensor couple of days ago, had to move the %s to nvalue instead of svalue:

Code: Select all

http://192.168.1.3:8080/json.htm?type=command&param=udevice&nvalue=%s&idx=199&svalue=0
(this is according to the wiki )


Result:

First measurements

Thnx... next step is integration with my ventilation system (using the 'afzuigkap' (cooking fumes), CO2 level, geofence status, in and outside temperature)
