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.

Follow the steps
Simply follow the steps and connect the Candle Controller to your wifi. You could skip making a web address at mozilla-iot.org.

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 attach the radio module. It will allow the controller to communicate with all the other Candle devices.

Getting to know the Candle Manager

Pic
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. You shouldn't have to change any settings. 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.

If you prefer your temperature in Fahrenheit, you can select this in the add-on's settings page.

 

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:

Installing Voco

Done!

Have fun exploring all the capabilities of your new privacy friendly smart home controller!
