Schematics

Edge Wiring Schematic

Using jumper wires, connect the hardware as shown. The MCP3008 is not necessary. Similar logic can be achieved by reading the signal from the Soil Moisture Sensor directly through the GPIO. This creates a boolean True when moist, and False when dry

Code

Herbert Edge Project

Signup for the free tier of the nio Platform at https://account.n.io/signup. Install the nio binary onto your Raspberry Pi and get this project using the nio CLI with the command `nio new my-plant -t https://github.com/tlugger/herbert_edge.git`

Herbert Dashboard

Download the edge repository. Configure your nio Platform pubkeeper configuration settings in `config.js`. Run the development server with `npm start`
