Somfy TaHoma Developer Mode

Getting started

1. Open the TaHoma By Somfy application on your device 📱.
2. Navigate to the Help & advanced features ▶️ Advanced features menu in the application.
3. Activate Developer Mode by tapping 👇 7 times on the version number of your gateway (like 2025.1.4-11).

By completing these steps, you enable the local API on your TaHoma box 🚀.

4. Generate a token from the Developer Mode menu to authenticate your API calls.

Note

Multiple tokens can be generated, but keep in mind that they can only be 👀 read and copied at the time of their creation. Ensure you save them securely for future use.

Security

TLS certificate

Warning

Due to the local nature of the API, the TaHoma box uses a certificate signed by a self signed authority.

To avoid security issues, add the following authority to your HTTPS client trust store: https://ca.overkiz.com/overkiz-root-ca-2048.crt

API Authorization

All local api calls must be authorized. This authorization is made using the Bearer authentication scheme and the token retrieved previously.

Simply add the Authorization header when making request.

Authorization: Bearer <token>

Discovery

You can find your TaHoma box on the local network using the mDNS protocol.

TaHoma boxes with developer mode enabled broadcast a service with:

Service Type: _kizboxdev._tcp

TXT:

Key	Value
gateway_pin	gateway pin (eg. 1234-5678-9012)
api_version	Version of the available REST API (eg. 1)
fw_version	Firmware version of the TaHoma (eg. 2019.4.3)

Warning

Host name and service name are not a reliable way to identify a TaHoma by its pin. The TXT record gateway_pin has to match.

API Documentation

You are now ready to use this local API.

Get API details by reading the specification in docs/openapi.yaml or browse and try it online using swagger-ui.

Rate limits

There is no rate limiting on this local API. However, be aware that if you call the API too frequently, the gateway might be overloaded which will result in an unwanted latency during products control.

We advise you to call the required API endpoint when your application starts and use events to get future updates.

For example:

• Call /setup at application start
• Register event listener with /events/register
• Fetch events on /events/{listenerId}/fetch once every second at most

Caution

Our support teams are available if you have any problems or questions regarding the use or operation of the TaHoma system.

However, for questions related to the development of third-party software using this API, please refer to this gitHub project
