A pimatic plugin for modules based on the [BME280](https://www.bosch-sensortec.com/bst/products/all_products/bme280) sensor. It uses the `node-bme280` driver from [CLCL/node-BME280](https://github.com/CLCL/node-BME280).

## Configuring device

Add a device via the web UI or by editing the config file.

```

    {

      "class": "BME280Sensor"

      "id": "bme280-test",

      "name": "BME280 test",

      "device": "i2c-1",

      "address": "0x76",

      "interval": 10000,

      "xLink": "",

    }

```

Check using `dir /dev/i2c*` to see the name of your device. USe `i2cdetect` to determine the address. If you can't find this command use `sudo apt-get install -y i2c-tools`.

```

pi@raspberrypi:~/$ i2cdetect -y 1

     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f

## Raspberry Pi setup

Copied steps from here: https://learn.sparkfun.com/tutorials/raspberry-pi-spi-and-i2c-tutorial#i2c-on-pi

I2C is not turned on by default. We can use `raspi-config` to enable it.

1. Run `sudo raspi-config`.

2. Use the down arrow to select `9 Advanced Options`

3. Arrow down to `A7 I2C`.

4. Select `yes` when it asks you to enable I2C

5. Also select `yes` when it tasks about automatically loading the kernel module.

6. Use the right arrow to select the `` button.

7. Select `yes` when it asks to reboot.

The system will reboot. when it comes back up, log in and enter `ls /dev/*i2c*`.

The Pi should respond with `/dev/i2c-1` which represents the user-mode I2C interface.
