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 %}
