How to start data logging with it?

Before going live with environmental data measurement, you'll have to connect your TeHyButton with a browser to set up an HTTP URL of the data web server and provide your wifi network credentials for internet connection.

Requirements.

The module requires a 3.4 to 11 Volt input voltage. It also requires a connection to a wifi network to send the sensor data.

How to configure the device?

The device has a preinstalled code. In a setup mode, it acts as a wifi station, you'll have to connect your computer to a wifi network TeHyBug_xxxxx and open in your browser the URL: http://192.168.1.1/ a configuration web page will open, where you'll have to provide your wifi credentials so that your TeHyBug can connect to the internet, you will have two choices:

• to use a tehybug.com server as a data server (you'll have to signup at tehybug.com for this and provide your unique TeHyBug key in your account),
• or to use your own web host like Raspberry Pi or any other web host for data fetching where you'll be able to set your own custom URL,
• or to use your own MQTT broker like Raspberry Pi or any other MQTT broker for publishing sensor data where you'll be able to set your own MQTT host,
• or use node-red, Blynk, thingspeak or Domoticz home automation system for logging and displaying data.
