Radio Smart LED Strip
This guide walks you through the Radio Smart LED Strip project. You'll control the LED strip from Node-RED, and the 16 A relay lets you switch an appliance as well.
Block Diagram
Requirements
-
Either the Control Set or these individual components:
- 1x Cover Module
- 1x Core Module
- 1x Power Module
- 1x AC/DC adapter 5 V/4 A (or a higher current rating)
- 1x 3D-printed enclosure BCE301
-
Other components:
- 1x Radio Dongle (not included in the kit)
- 1x RGB or RGBW digital LED strip (not included in the kit)
- Micro USB cable (not included in the kit)
-
One of the following:
- HARDWARIO Playground installed (recommended) See Playground Installation for details.
- Raspberry Pi with the HARDWARIO Raspbian distribution See Raspberry Pi Installation for details.
- HARDWARIO Firmware Tool installed See Firmware Flashing Tool for details.
Firmware Upload
You'll upload the firmware to the Core Module with HARDWARIO Playground.
Step 1: Connect the Core Module to your computer with a Micro USB cable
Step 2: Flash the firmware
Start HARDWARIO Playground, select the hardwario/twr-radio-power-controller- firmware for your strip on the Firmware tab and upload it to the Core Module:
If your LED strip is 144 LEDs RGBW:
hardwario/twr-radio-power-controller-rgbw144
If your LED strip is 150 LEDs RGB:
hardwario/twr-radio-power-controller-rgb150
If your LED strip is 72 LEDs RGBW:
hardwario/twr-radio-power-controller-rgbw72
warning
Flashing Core Module R1 and R2 The older Core Module 1 and the newer Core Module 2 are flashed differently; see Core Module R1 and R2 comparison in the Hardware section.
Step 3: Disconnect the Micro USB cable from the Core Module and the computer
success
Your firmware is now uploaded.
Hardware Assembly
Watch this short video for a simple step-by-step demonstration:
Playing the video loads it from YouTube (Google).
Step 1: Start with the Power Module
warning
Check that the power adapter is not plugged into the Power Module.
Step 2: Plug the Core Module onto the Power Module
Step 3: Plug the Cover Module onto the Core Module
Step 4: Put the assembled modules into the BCE301 enclosure and secure it with O-rings
Step 5: Connect the LED strip to the connector on the right side
Step 6: Plug in the 5 V DC power jack
Playground Setup
danger
If you use the new HARDWARIO Playground, open the Functions tab instead of http://localhost:1880/. Pairing now happens on the Devices tab, and you test communication on the Messages tab.
Step 1: Open Node-RED in your web browser
Step 2: You should see an empty workspace with Flow 1
Step 3: Import the following snippet into the flow (Menu >> Import >> Clipboard) and click the Flow 1 tab, then deploy

It looks like this:
info
The snippet adds buttons for the gateway and radio commands, which are sent over MQTT.
Step 4: Deploy the flow with the Deploy button in the top-right corner
Step 5: Open the debug tab
info
The debug tab shows all MQTT messages.
Step 6: Click the List all gateways button. The debug tab should show a response like this
success
You now have working Node-RED, MQTT, HARDWARIO Radio Dongle and HARDWARIO Gateway.
Radio Pairing
In this section, we'll establish a radio link between the Radio Dongle and the Radio Smart LED Strip.
In Node-RED, follow these steps:
Step 1: Click the Start node pairing button
Step 2: Plug the power adapter into the Radio Power Controller to send the pairing request (the red LED on the Core Module should also light up for about 2 seconds)
Step 3: Click the Stop node pairing button
success
You now have a radio link between the node (Radio Smart LED Strip) and the gateway (Radio Dongle).
Communication Test
In Node-RED, follow these steps:
Step 1: Switch to the debug tab on the right
Step 2: Import the following snippet into the flow (Menu >> Import) and click the Flow 1 tab

Step 3: Edit the set node id node and change "Replace with" to your node ID, for example kit-power-controller:0 (click List paired nodes to find your node ID)
Step 4: Click led-strip set color #ff0000
