Raspberry Pi Pico app to read BME280 sensor data and send it to Home Assistant.

Made in Go with [TinyGo](https://tinygo.org/).

## Requirements

* [TinyGo](https://tinygo.org/getting-started/install/) - TinyGo installation guide

## Deployment

1. Clone this git repository `git clone https://git.metaunix.net/gballan/pico-weather`.
2. Copy `config.go.example` to `config.go` and modify the values to match your environment.
3. Hold down the **BOOTSEL** button on your Raspberry Pi Pico 2W.
4. Plug in your Pico to a USB port on your PC.
5. Wait 2-3 seconds then release the **BOOTSEL** button.
6. Flash the program to the Pico: `tinygo flash -target=pico2-w .`.
  a. **Note**: On Pop!_OS I needed to open the file browser and mount the RP2350 partition manually while tinygo was attempting the flash, otherwise it would fail.
7. Monitor the app: `tinygo monitor`.

At this point, you should be able to deploy this. Unplug the Pico, connect your BME280 sensor and power it back on - you should start receiving data in Home Assistant under the name you set with `NodeName`.
