Somfy Home Center 3 integration
In this blog I’ll show you the Quick App I created to connect to the TaHoma switch ecosystem via the Somfy API.
To come straight to the point, every smart home owner who has Somfy equipment wants to have it connected to his Home Center 3 in order to integrate the devices into scenes and build cool automations with it. Integrating a Somfy product with the Home Center 3 is not that easy, but I managed to create a Quick App to integrate the TaHoma switch!
How Somfy works with the HC3
The Roller Shutter 3 Z-wave module made by FIBARO allows you to control electric blinds, awnings, roller shutters, roller blinds, and gates with the HC3. For Somfy devices this module is not an option, so I created a Quick App that reads the Somfy devices from the TaHoma switch box and creates child devices with the
com.fibaro.rollerShutter device type. This allows you to control the devices in almost the same way the Roller Shutter 3 Z-wave module does.
The Quick App supports the following device types:
|Exterior venetian blind||No|
Because I only can test motorized roller shutters, I got help from Tim (Peertje Projecten) who gave me access to his TaHoma Switch so that I could test more device types!
The standard open, close and level commands are supported. Automatically the Favorite Position button is mapped to the My button on the Somfy system. How cool is that!
Most Somfy devices are not capable of reporting their status. Devices that use the IO protocol are capable but at the moment this is not implemented in this Quick App. You need to be aware of this when creating scenes with the HC3. Maybe I will implement this in the future, but I can’t say when.
You can download my Somfy TaHoma Switch Quick App and documentation from the FIBARO Marketplace.
Before you can integrate your Somfy devices into the Home Center 3 (HC3) you must meet the following prerequisites:
- You need a TaHoma switch,
- Your Somfy devices needs to be configured and connected to the TaHoma switch via the TaHoma app,
- My Somfy TaHoma Quick App installed on your HC3.
Quick App installation
- Start your favorite browser and open your Home Center 3 dashboard by typing the correct URL for your HC3,
- Go to Settings and Devices,
- Click the blue + icon to add a new device,
- In the Add Device dialog click on Other Device,
- Choose Upload File and upload the
.fqafile downloaded from the FIBARO Marketplace.
- Additionally you can change the icon of the Quick App with the attached icon.
Quick App configuration
- Go to Settings and Devices,
- Expand the imported Tahoma Switch device,
- Select the Variables tab,
- Fill in the userid and userPassword fields with the credentials you use to login the TaHoma app on your phone or tablet.
- If you press the blue Save button the Quick App will be initialised, reads all devices from the TaHoma box and automatically creates child devices in your HC3.
Block scene example
With motorised roller shutters you don’t have to keep manually changing your blinds when you go to bed at night. With this example I’ll show you that my Quick App fully supports block scenes by creating a block scene to close the roller shutters when you activate the Night profile in the HC3:
Lua scene example
In this example I’ll show you how to automatically lower your exterior screens when the sun gets strong by reading the current UVI value from my Ventus W830 weather station:
local uvi = fibaro.getValue(50) -- read the current UVI if uvi > 4 then fibaro.call(60, "close") -- send close to the end
This will automatically maintain an optimal temperature inside your home with just 4 lines of code!
Using the “My” (or favorite) position
Somfy remotes have a my button to easily set your blinds to a favorite position. In the Quick App I mapped the Favorite position button of the child devices to the my button action. Most Somfy devices are based on the RTS protocol and don’t allow to set a certain level. By assigning a favorite position to your my button you can still set your blinds to a certain position in a Home Center 3 scene.
The Somfy API may change in the future and I cannot provide any support or advice of any kind when you use my Quick App. I made this Quick App in my spare time as a hobby and am publishing the Quick App for others to enjoy the integration in their smart homes too.
This Quick App has been written in such a way that it respects the Somfy API guidelines. Your use of the Somfy TaHoma switch Quick App is solely at your own risk. If your public IP address is blocked by the Somfy API servers, that is your own responsibility. If Somfy changes or stops offering the API that this Quick App uses, I will not be responsible for the failure of automations made with this Quick App.
