The TIG stack is a modification of the TICK stack, which is a group of applications provided by InfluxData. It is comprised of applications that receive, store, visualize, and act on time-based data. We’ll only be using the “T” and “I” components of the TICK stack (Telegraf and InfluxDB) and we’ll be adding the “G” … Read More

In part II of the tutorial, we got our NodeMCU flashed, and optionally set up some sensors on another NodeMCU. In this tutorial, we’ll set up our MQTT and Node-Red servers, which will give us the ability to relay and take action on data that we receive.

In part I of the tutorial, we got our relay hardware all set up and ready to go. Now it’s time to get the our NodeMCU firmware squared away. Optionally, at the end of this tutorial, I’ll show you how to set up another NodeMCU with some sensors.

My newest hobby is mucking around with the Internet of Things (IoT). A while back I bought several NodeMCU’s from eBay for almost nothing. Along with a relay board (also from eBay), some creative wiring, and a bit of software, I’ve managed to put together a neato remote controlled relay board. In this demo I’ll actually … Read More
