Hi bfaliszek

First of all thank you very much for sharing such a valuable project with community.
I have fully reproduced your project with the same hardware set and also InfluxDB and Grafana and I have found some bugs because I was not able to get the correct sensor values using the code. Let me share how I tuned the Arduino code.

In ClosedCube_HDC1080.cpp::begin function Wire.begin(); line needs to be enabled. Otherwise none of the below code gives the correct data

  Serial.print("Manufacturer ID=0x");
  Serial.println(hdc1080.readManufacturerId(), HEX); // 0x5449 ID of Texas Instruments
  Serial.print("Device ID=0x");
  Serial.println(hdc1080.readDeviceId(), HEX); // 0x1050 ID of the device

  printSerialNumber();

I have restored the function Wire.begin(); line again and disabled SoftwareReset option,

void ClosedCube_HDC1080::begin(uint8_t address) {
	_address = address;
	Wire.begin();
	
	// https://github.com/closedcube/ClosedCube_HDC1080_Arduino/pull/8/commits/724a233c76da13d4e559262eb6eeaa5037d33f09
	// HDC1080_Registers reg;
	// reg.SoftwareReset = 1;
	// writeRegister(reg);
	// delay(100);

	setResolution(HDC1080_RESOLUTION_14BIT, HDC1080_RESOLUTION_14BIT);
}

2. Based on TI HDC1080 reference code HDC1080 Arduino Example Code v1.0 in page http://www.ti.com/product/HDC1080
   I added some typecasts and the most important diff I have seen regarding to receive the wrong temperature value 125.0 is that what was fixing this value is to change the delay(9) to delay(20) as written in sample TI code. I am sharing the final ClosedCube_HDC1080.cpp code I have used.

Here is the the wiring

I'm attempting to install this library as a ZIP file, but the Arduino 2.0.3 IDE throws:
Error: 13 INTERNAL: Library install failed: library not valid
This library's description notes that it was based on three other libraries; I've installed each of them. Are there any other dependencies I might have failed to install that would cause this error to pop up?

// Pass environmental data from ENS210 to CCS811
ccs811.set_envdata210(float(hdc1080.readTemperature()), float(hdc1080.readHumidity()));

Need to refer CCS811 env data datasheet U16 format.

How does it feel that this CJMCU-8118 measurement data is not accurate! It's code! It's still a module problem

Hello. Do you have example with reading and writing baseline? Thnx :)
