[Ethereum] Metamask – Trying to call a function on a non-contract address

Not using Metamask alone, but you can in combination with other tools. One such tool is MyEtherWallet; go to the "Contracts" tab, enter the contract address and ABI, click Access, and then choose "Metamask/Mist" as the means you want to access your wallet. Then MyEtherWallet will give you the UI to construct the transaction, and when it's time to broadcast it, it will give you a Metamask popup to sign and transmit it.
