Somfy is a French maker of motors and controls for shutters, blinds, awnings, gates and garage doors. Its TaHoma and Connexoon gateways link those motors, over radio protocols such as io-homecontrol and RTS, to one app.

Works with full table
Somfy motors talk to a gateway over Somfy's own radio protocols, io-homecontrol and RTS, and in some regions Zigbee. The TaHoma gateway then connects to the TaHoma app and to Somfy's cloud, with a local API available in Developer Mode on most gateways. Third-party platforms mostly reach the motors by way of that gateway.
That suits anyone with Somfy shutters, blinds or awnings who wants scenes, schedules and voice control from one place. It is weaker for a Matter-first setup, since Somfy has described Matter as a bridge plan and we found no Somfy-certified Matter product.

The current app, published by Somfy. It supports the TaHoma switch, Connexoon, Connectivity kit, TaHoma Premium and TaHoma DIN-Rail hubs, with scenes, schedules and Alexa, Google Assistant and Apple HomeKit control. Version 2.8.0 on the App Store adds up to three hubs in one app. The Android link comes from a third-party app tracker, and we could not open the Google Play page itself.
An older app, still listed on the App Store, for the TaHoma box with scenarios, schedules and alarm sensors. A 2023 update note and the new-generation wording on the separate app suggest it has been superseded, but the listing does not say so.
For installers, dealers and manufacturers rather than homeowners. It configures and troubleshoots TaHoma switch installations, including Zigbee motors, and needs a SomfyPro login.

| Platform | Status | What it means | Sources |
|---|---|---|---|
| Connection | |||
| io-homecontrol and RTS | Official | Somfy's UK page says the Connectivity kit uses two Somfy radio protocols, io home-control and RTS, and that the TaHoma switch brings together over 300 Somfy and partner product ranges. A third-party guide describes io-homecontrol as an encrypted two-way 868 to 870 MHz standard, and Home Assistant notes that stateless RTS devices do not report their state back. | Somfy UK: smart home Selora Homes: io-homecontrol Home Assistant Overkiz |
| Zigbee | Official | Somfy North America's 2023 release covers the TaHoma switch and Zigbee motors for interior window coverings, and the TaHoma pro app lists Zigbee motor management. A third-party guide says North American Somfy hubs and motors use RTS and Zigbee rather than io-homecontrol. | Somfy NA: Apple Home press release TaHoma pro app listing |
| Wi-Fi, Bluetooth, Z-Wave, Thread | Not mentioned | None of these are described as the way Somfy motors connect on the Somfy pages we opened. Thread appears only in Somfy's Matter plans, where Somfy says it sits on Thread Group committees. Home Assistant's page notes Zigbee and Z-Wave devices behind a gateway are not handled by its Somfy integration. | Somfy NA: Matter article Home Assistant Overkiz |
| Matter | Not mentioned | Somfy says it will use TaHoma as a Matter bridge, turning Zigbee 3.0 motors into virtual Matter motors, and in October 2023 targeted a first Matter motor and control from 2024 in small quantities. Its FAQ gives no date and says Zigbee motors will not become Matter compatible through a firmware update. Wikipedia reports no Matter-certified Somfy product announced as of 2025. Third-party options exist: mediola's certified Matter bridge for RTS (January 2024) and a community Matterbridge plugin for TaHoma that can use the cloud or Developer Mode. | Somfy NA: Matter article Somfy FAQ: Matter Wikipedia: Somfy mediola Matter bridge Matterbridge plugin |

| Apple Home | Official | Somfy North America announced Apple Home certification on 26 September 2023 for the TaHoma switch and Zigbee motors for interior window coverings, with Siri control.

| Home Assistant | Yes | Home Assistant's built-in Overkiz integration covers the TaHoma, TaHoma Switch, Connexoon and other gateways, and is not maintained by Somfy. Cloud mode polls every 30 seconds. Local mode needs Developer Mode and a token, polls every 5 seconds and works without internet, but lacks scenarios and climate entities. Stateless RTS devices do not report their state. | Home Assistant Overkiz |
| Homey | Community | A community app by RockSoft Solutions, with Lennart Kuijs and Adrian Rockall credited, not by Somfy or Athom. It needs a TaHoma, Connexoon, Switch or Connectivity kit, and the store page lists Homey Cloud, Pro, Pro mini and Self-Hosted Server while marking every device Homey Bridge required. We could not resolve how that applies to each model. The store page shows only cloud access, but a forum post says a test version added local access for TaHoma and TaHoma Switch through Developer Mode. | Homey app page Homey community thread |
| openHAB | Yes | openHAB's official add-on list includes a Somfy Tahoma binding for TaHoma and Connexoon gateways. It works in cloud mode, or locally in Developer Mode, though Connexoon does not support Developer Mode and group actions fail locally. The page does not mention the TaHoma Switch. A forum thread reports firmware 1.29 breaking local mode around January 2025, with later firmware seeming to fix it. Somfy does not maintain the binding. | openHAB Somfy Tahoma binding openHAB community thread |
| Node-RED | Community | No dedicated local node is mentioned in a Node-RED forum thread. A user reached the local API with the HTTP request node and, after trouble, with curl through the exec node, and another suggested a cloud-oriented overkiz node, untested. | Node-RED forum |
| Samsung SmartThings | Official | Somfy's UK page says TaHoma switch devices are controlled through the SmartThings app and are Works with SmartThings certified, and Somfy's North American page describes linking TaHoma by adding a Somfy Window Treatment device. A community-made Edge driver for Connexoon, by Damien Emmerson, also exists. | Somfy UK: platforms Somfy NA: TaHoma integrations SmartThings community driver |

| Control4 | Official | Somfy's UK page lists a Control4 driver for the TaHoma switch, certified and validated by both companies, covering Zigbee and RTS solar protection motors. Somfy North America lists TaHoma, myLink and UAI Plus drivers. A separate paid TaHoma Switch driver by Hop Soft is sold on DriverCentral, and Crestron, Savant and Elan drivers are also listed. | Somfy UK: platforms Somfy NA: Control4 DriverCentral: Hop Soft driver |
| Philips Hue | Official | Somfy North America says the TaHoma app can connect to a Philips Hue Bridge so lights and shades share scenes. | Somfy NA: TaHoma integrations Works with Philips Hue |
| IFTTT | Official | Somfy's October 2023 press release lists IFTTT among five ecosystems it integrates with directly, and its UK platforms page metadata mentions IFTTT. Somfy North America's integrations page does not list it, so availability may vary by region. | Business Wire release Somfy UK: platforms |
| TaHoma Developer Mode (local API) | Official | Somfy's Developer repository documents a local REST API on most TaHoma gateways, switched on by tapping the gateway PIN seven times in the app and generating a token. It has an OpenAPI specification and mDNS discovery and no stated rate limit. The first-generation square TaHoma box and the Connectivity Kit are excluded. We could not confirm the status of Somfy's older Open API portal. | Somfy TaHoma Developer Mode |
