6 years ago As Air quality is related to CO2 PPM in domoticz I suggest I will add a formula to the simple Sonoff SC air quality percentage as 100% would be 500ppm (Excellent) to 10% as 2300ppm (Poor) - 500 + ((100 - sc_value[4]) * 20)

6 years ago @arendst Can I ask you to please add a similar solution for the BME680 VOC measurement -> Domoticz?
As an initial hack, I tried the change below, but it's reporting air quality of 0 constantly (the web page reports kOhms in the range 20 to 200).
`$ git diff sonoff/xsns_09_bmp.ino diff --git a/sonoff/xsns_09_bmp.ino b/sonoff/xsns_09_bmp.ino index 01eb297..5b9c95d 100644 --- a/sonoff/xsns_09_bmp.ino +++ b/sonoff/xsns_09_bmp.ino @@ -465,7 +465,10 @@ void BmpShow(boolean json) mqtt_data, bmp_name, temperature, (bmp_model >= 2) ? json_humidity : "", pressure, (Settings.altitude != 0) ? json_sealevel : "");
}

6 years ago Could you replace the following code:
#ifdef USE_DOMOTICZ
if (0 == tele_period) DomoticzTempHumPressureSensor(temperature, humidity, pressure);
#endif // USE_DOMOTICZwith the one below:
#ifdef USE_DOMOTICZ
if (0 == tele_period) {
DomoticzTempHumPressureSensor(temperature, humidity, pressure);
#ifdef USE_BME680
if (bmp_model >= 3) { DomoticzSensor(DZ_AIRQUALITY, gas_resistance); }
// if (bmp_model >= 3) { DomoticzSensor(DZ_AIRQUALITY, (char *)gas_resistance); }
#endif // USE_BME680
}
#endif // USE_DOMOTICZPlay with the two gas_resistance lines and report which one provides to correct result.

6 years ago This one reports the kOhm value correctly:
#ifdef USE_DOMOTICZ
if (0 == tele_period) {
DomoticzTempHumPressureSensor(temperature, humidity, pressure);
#ifdef USE_BME680
// if (bmp_model >= 3) { DomoticzSensor(DZ_AIRQUALITY, gas_resistance); }
// if (bmp_model >= 3) { DomoticzSensor(DZ_AIRQUALITY, (char *)gas_resistance); }
if (bmp_model >= 3) { DomoticzSensor(DZ_AIRQUALITY, (uint32_t) g); }
#endif // USE_BME680Domoticz is reporting this a ppm rather than kOhm. Would appreciate ideas how to massage this into something that Domoticz could interpret as indoor air quality. This code is from the Domoticz main/WebServer.cpp file:
if (airquality < 700)
root["result"][ii]["Quality"] = "Excellent";
else if (airquality < 900)
root["result"][ii]["Quality"] = "Good";
else if (airquality < 1100)
root["result"][ii]["Quality"] = "Fair";
else if (airquality < 1600)
root["result"][ii]["Quality"] = "Mediocre";
else
root["result"][ii]["Quality"] = "Bad";
Hi,
The patch below is needed to get the Sonoff SC to report air quality and sound level to Domoticz. The sound level is reported as the "Sensor idx 6 Count" (air quality is already "Sensor idx 9 AirQuality").
