The `Blockchain` sensor platform displays Bitcoin wallet balances from [blockchain.info](https://blockchain.info).
To add the Blockchain sensor to your installation, specify a list of bitcoin addresses to watch in the `configuration.yaml` file. The sensor state will be the sum of the balances of all addresses listed.
```yaml
# Example configuration.yaml entry
sensor:
- platform: blockchain
addresses:
- '1BMsHFczb2vY1BMDvFGWgGU8mkWVm5fupp'
- '183J5pXWqYYsxZ7inTVw9tEpejDXyMFroe'
```
Configuration variables:
- **addresses** (*Required*): List of bitcoin wallet addresses to watch.
