The Etherscan sensor platform displays Ether and ERC-20 token balances from Etherscan.io.

To add the Etherscan sensor to your installation, specify an Ethereum address to watch in the configuration.yaml file. You can also optionally provide a token name to retrieve and ERC-20 token balance. If no token is provided then the balance retrieved will be in ETH. You can also optionally provide the token contract address in case the token name is not found.

# Example configuration.yaml entry
sensor:
  - platform: etherscan
    address: '0xfB6916095ca1df60bB79Ce92cE3Ea74c37c5d359'
  - platform: etherscan
    address: "0xfB6916095ca1df60bB79Ce92cE3Ea74c37c5d359"
    token: OMG
  - platform: etherscan
    address: "0xfB6916095ca1df60bB79Ce92cE3Ea74c37c5d359"
    token_address: "0xef68e7c694f40c8202821edf525de3782458639f"
    token: LRC
