Story

Make your own smart climate station with an LED thermometer that you can place indoors or outdoors so you se all the temperatures nice on the special LED strip with the scale on it.

1. Build hardware

You will need Power Controller Kit from HARDWARIO IoT Kit and some Tags that will work as the climate station altogether.

And you will need the upgraded LED strip with the scale.

Put it all together like this and you are ready to move onto the next step.

2. Flash firmware

Download HARDWARIO Playground,
Flash firmware to the Core Module that was made for this project. You will find in the Playground by name: bcf-generic-node-power-module-rgbw72
How to flash firmware is shown in the documentation.

3. Pair the Core Module

You need to pair the Core module with the Radio dongle that you are using, follow the instructions below to see how it is done.

Connect your USB Radio Dongle to your computer.
Open HARDWARIO Playground

Click Start Pairing the LED on the dongle should start blinking
Connect the device that you want to pair into your computer or insert the batteries.
Wait for the device to appear in the table
It should add the device with the Alias: generic-node:0

After you did all this you can unplug the device from the computer and insert the batteries, it will run on them without a problem. Next steps will be done on the computer, so you can leave the device and focus on the NODE-Red.

4. Import flow

Open Node-RED in the Playground or Raspberry Pi and import this flow from the Attachements in the Menu -> Import -> Clipboard.

Do not forget to hit "Deploy" in the top right corner to apply the changes.

This flow collects all the data from the device and put them into the gauges, also it sends the temperature back to the LED strip.

5. Test your device

Place the LED thermometer on the visible place so you will always see the temperature in your house, you can also see all the different values from all the other sensors in Node-RED dashboard.

Summary

You can place this device into your house, into the different rooms, so you always know what temperature is there, connect your heating to it and make your house a little bit smarter.

You can also place it outside, just look out of the window and see the temperature at any time of day.

It is easy to integrate the device into the Blynk or Grafana, so you see all the values in different paces than just Node-RED dashboard.
