ECOWITT CO2 Sensor data

philpugh · Post by **philpugh** » Wed 01 Sep 2021 3:19 pm

I think this may be a problem in data collection from the WH45 Ecowitt CO2 monitor.

The data being sent to CumulusMX is :

2021-09-01 16:08:25.108 ProcessData: Payload = PASSKEY=********************&stationtype=GW1000A_V1.6.8&dateutc=2021-09-01+15:08:24&tempinf=64.4&humidityin=67&baromrelin=30.472&baromabsin=30.307&tempf=63.3&humidity=69&winddir=332&windspeedmph=2.24&windgustmph=4.47&maxdailygust=10.29&solarradiation=138.73&uv=1&rainratein=0.000&eventrainin=0.000&hourlyrainin=0.000&dailyrainin=0.000&weeklyrainin=0.000&monthlyrainin=0.000&yearlyrainin=30.079&totalrainin=30.079&temp1f=70.16&humidity1=57&temp2f=68.00&tf_co2=68.0&humi_co2=63&pm25_co2=3.0&pm25_24h_co2=3.1&pm10_co2=3.7&pm10_24h_co2=3.7&co2=447&co2_24h=487&wh65batt=0&batt1=0&batt2=0&co2_batt=6&freq=868M&model=GW1000_Pro

But the Extra Sensor shows:

Minor differences due to data cut/paste but it seems to miss the two values in red?

A bit more info...

I suspect that this is one of the first WH45 units to be reported here? Having looked at the WIKI for the webtags (so I can store the data into my MariaDB) there is a lack of info which I can probably help with.

Interestingly the WS VIEW app reports the following:

Which shows the current values and the calculated AQI values for current and 24hrs average.

I think it is a case of what is documented (unofficially), not matching what is actually sent. I've fixed this in the next patch release, thanks.

Thanks Mark

I will await the next release!

Don't have Debug diags turned on but mine looks Ok???

@phil23 ...

Am I missing something ?

Only the CO2 figures agree.

I did a screen shot several minutes after the log file and the capture from the WS. View. App was about 10 mins later. The WH45 was placed by an open window and the 2.5 and 10 measures fluctuate noticeably. As it is new I am expecting it to settle down over time.

Hmm, so it could be different versions are sending different data?

Could you turn on debug and data logging for a while then post the log file please?

Also Phil & Phil, can you let me know the firmware versions of your GW1000's?

Mark: My GW1000 is V1.6.8

However...

Looking at the code

private void ProcessCo2(NameValueCollection data, WeatherStation station)
{
// tf_co2
// humi_co2
// pm25_co2
// pm25_24_co2
// pm10_co2
// pm10_24h_co2
// co2
// co2_24

if (data["tf_co2"] != null)
{
station.CO2_temperature = Convert.ToDouble(data["tf_co2"], CultureInfo.InvariantCulture);
}
if (data["humi_co2"] != null)
{
station.CO2_humidity = Convert.ToInt32(data["humi_co2"], CultureInfo.InvariantCulture);
}
if (data["pm25_co2"] != null)
{
station.CO2_pm2p5 = Convert.ToDouble(data["pm25_co2"], CultureInfo.InvariantCulture);
}
if (data["pm25_24_co2"] != null)
{
station.CO2_pm2p5_24h = Convert.ToDouble(data["pm25_24_co2"], CultureInfo.InvariantCulture);
}
if (data["pm10_co2"] != null)
{
station.CO2_pm10 = Convert.ToDouble(data["pm10_co2"], CultureInfo.InvariantCulture);
}
if (data["pm10_24h_co2"] != null)
{
station.CO2_pm10_24h = Convert.ToDouble(data["pm10_24h_co2"], CultureInfo.InvariantCulture);
}
if (data["co2"] != null)
{
station.CO2 = Convert.ToInt32(data["co2"], CultureInfo.InvariantCulture);
}
if (data["co2_24"] != null)
{
station.CO2_24h = Convert.ToInt32(data["co2"], CultureInfo.InvariantCulture);
}
}

The RED variables are at odds with what the station is reporting (i.e. missing the "h" from 2p5 24 hr average and "24h" from C02 )?

I am using the HTTP ECOWITT Device

Ahhh.....

Changing the station to GW1000 It works!

Now...

Should I expect the Trends graph to work? Adding the Ecowitt CO2 Sensor causes the button to be displayed but there is no json file data.

Yep, that is what I have changed.

The GW1000 uses a completely different API.

The puzzle is @Phil23 is working - who I assume is using the HTTP Station (Ecowitt) as his profile says the main station is a Davis. Phil23?

A log file from @Phil23 will be a great help.

philpugh · Post by **philpugh** » Sat 04 Sep 2021 6:48 pm

Mark. Unless I misread the code it would appear you have two different procedures for handling the WH45. One in the GW1000 and one in the Ecowitt HTTP area?

Hi Mark,

Mine appears to be working fine on occasions, but it has been pointed out that there is a glitch in the 24 Hr data at times.

Firmware is 1.6.8 & this station has no association with my main Davis.
It runs separately on a Pi of it's own.

Have just enabled Debug & will grab some diags files once I'm Up.

Phil.

Was going to comment on the number of high number of realtime entries the the log & the option to reduce these for readability,
but on going a step forward found they here easily removed in notepad with another Dreaded REGEX,
^.{24}Realtime\[\d{1,3}\].*\n?

https://regex101.com/r/yghwW2/3

A thanks to @beteljuice for pointing out the regex101 site, it's excellent.
Also discovered there this morning there is a chat, where some helpful individual assisted me with the above expression.
(Translation, more like wrote it for me).....

Cheers.

Yet Another Regex
^.{24}WH45 CO.*\n?

Easily turn the log file into this....

Phil23: According to the manual the WH45 only gathers data every 1 minute on "mains" (i.e. external 5V) or every 10 mins on battery power. I notice you are polling every 10 seconds are you seeing changes in less than 1 minute intervals?
