Steps
Confirm the installed TaHoma hardware model first; Somfy's documented local API Developer Mode is only supported on TaHoma Switch, TaHoma Premium, and TaHoma DINRail gateways, not all TaHoma products
Enable Developer Mode on the gateway (documented multi-tap-on-PIN activation) and generate a local API token from the Developer Mode menu
Reference the official OpenAPI 3.0 spec published at the Somfy-Developer GitHub repo/GitHub Pages site for the exact local endpoints and authentication flow, rather than assuming a cloud-hosted public API exists
Test device availability status carefully; there are open, acknowledged bugs where the local API reports an io-homecontrol device as unavailable even though it's functioning, so don't treat the API's available flag as ground truth without a manual check
For integrations needing broader platform reach (Crestron/Control4/Elan-class systems), check current Somfy Synergy/partner-integration documentation rather than the consumer local API, since these are separate programs
Known gotchas
Somfy does not currently offer an open public cloud API for arbitrary third-party developers; what exists is a local-network Developer Mode API limited to specific gateway models
Somfy has deactivated Developer Mode on some device classes (e.g., older Connectivity Kit devices) in past updates, so a workflow validated on one customer's gateway may not port to another's without checking hardware/firmware first
