The `Blockchain` sensor platform displays Bitcoin wallet balances from [blockchain.com](https://blockchain.com).

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.

Currently, the original Bitcoin address format is supported.
For example, the newer Segwit and Taproot format are not supported.

```yaml
# Example configuration.yaml entry
sensor:
  - platform: blockchain
    addresses:
      - '1BMsHFczb2vY1BMDvFGWgGU8mkWVm5fupp'
      - '183J5pXWqYYsxZ7inTVw9tEpejDXyMFroe'
```
