The Candle controller 

The heart of Candle. It stores your data and manages your devices.

Browser based

Connect to the Candle with a tablet or laptop to manage your devices, create automations, or explore your data.

VOice control

Say bye bye to Alexa. Online voice services gather data about your private life, which reveals more than you think. Candle uses local voice control - no cloud connection required.

Making the Candle Controller

We don't sell it, you make it yourself.

1. Preparing the Micro SD card

Purchase all the parts mentioned in the shopping list below, and download the WebThings disk image for the raspberry pi

Plug the Micro SD card into your computer. Using the Etcher software you can 'flash' the disk image onto the micro SD card.

2. Setting up the Candle Controller

Power it up
Insert the SD card into the Raspberry Pi, and connect the power supply. After about 20 seconds it wil create a new temporary wifi hotspot.‌ 

On your laptop connect your wifi to this WebThings hotspot. A browser window will pop up automatically.

For a more detailed guide, click here.

Follow the steps
Simply follow the steps and connect the Candle Controller to your wifi. We recommend you skip making a web address at webthings.io.

Once done, the temporary wifi hotspot will disappear and you can re-connect to your home wifi. Open a new browser window and visit gateway.local.

3. Install the Candle Manager add-on

Go to settings, then add-ons, and click on the (+) icon in the bottom right.‌ Find the "Candle Manager" add-on and click 'Add'.‌


4. Create the receiver 

T‌he next step is to create the Candle Receiver. This is just an RF-Nano you plug into the Raspberry Pi. It will allow for encrypted communication with all the other Candle devices.

Getting to know the Candle Manager

Open the Candle manager
If you refresh the web page, you should now see the Candle Manager option in the menu. Select it.

The Candle manager allows you to upload the programming code into your Candle devices.

When asked to do so, plug the RF-Nano into an empty usb port on the Raspberry Pi.

Follow the steps
Select the 'Candle receiver' from the list, and click next. Then simply follow the steps until the upload is complete.

5. Install the MySensors add-on

The Candle devices communicate using the MySensors protocol. Install this add-on to teach the WebThings Gateway how to speak this language.

The Candle Receiver should now be available as your first 'thing'. Click on the (+) icon on the things overview page to add it.


6. Install the voice assistant (optional)

‌The Voco add-on will allow you to control your devices using your voice. It is 100% privacy friendly: it never communicates with any outside server.

T‌o install Voco please visit the detailed installation page:
