Setup Homebridge

Do the following on the computer that will run the HomeBridge instance:

1. Install Homebridge using npm install -g homebridge

2. Install this plugin npm install -g @townsen/homebridge-ntc Alternatively, if you want to run the plugin directly from this repository then in this plugin directory issue:

   npm install sudo npm link

3. Update your configuration file - see below for an example

Configuration

• accessory: "NTC"
• name: descriptive name
• refresh: Optional, time interval for refreshing data in seconds, defaults to 30 seconds.
• host: the remote host to use.
• recordpath: Optional, used by the fakegato history code to create an on-disk record of the observations. This preserves the history in case of a restart, and can be used to extract the observations manually. The name and the host are used to name the sensor device, which is then used as the filename.
