Additional Notes

To communicate with an Electric Imp using Johnny-Five w/ Imp-IO, you will need to upload the special Tyrion agent and device firmware through Electric Imp's IDE. We recommend you review Electric Imp's Getting Started before continuing.

Store your agent ID in a dot file so it can be accessed as a property of process.env. Create a file in your home directory called .imprc that contains:

export IMP_AGENT_ID="your agent id"

Then add the following to your dot-rc file of choice:

source ~/.imprc
