How to Get Voltage with a Grove Voltage Divider in Wio Node

by Fernando Ribeiro, posted in Hardware, Software

REST API

1) Connect the module to PORT1.

2) Run the following code:

import requests

res = requests.get('https://host/v1/node/GroveVolDividerA0/voltage_x3', headers = { 'Authorization': 'nodetoken' }) # or voltage_x10

if res.ok:
  print res.text

CLI

1) Connect the module to PORT1.

2) Configure the CLI:

wio login

3) Run the following command:

wio call nodetoken GET /v1/node/GroveVolDividerA0/voltage_x3 # or voltage_x10
