Somfy
Connexoon RTS
Connexoon RTS is the RTS-only version of the Connexoon box, sold for homes whose blinds and awnings predate io-homecontrol. Home Assistant supports it through Overkiz, cloud or local, but everything behind it is one-way.
The cheapest way to get an existing RTS installation into Home Assistant without touching a single motor, and the reason to be careful about what gets promised on top of it. RTS is one-way: the box transmits open, close, stop, and the stored `my` position, and no motor answers. Covers therefore appear in Home Assistant as stateless, so a dashboard slider is a command rather than a reading, and any automation that needs to know where a shade actually is needs a different sensor. Somfy has folded the Connexoon apps into the TaHoma app and the box is no longer the current product, with the TaHoma switch as its replacement. Local API support is the same as the rest of the line, which is worth taking even here: it removes the cloud round trip and the rate limit, though it does not create feedback that the radio protocol never had.
Hardware availability
TaHoma switch is the current hub in both Europe and North America, in two regional variants: the European unit adds io-homecontrol to RTS and Zigbee, the North American unit is RTS and Zigbee only because io-homecontrol is not sold there. TaHoma v2 and the Connexoon boxes are no longer marketed, and Somfy’s own product page labels the Connexoon box discontinued, but both stay supported by Home Assistant and both still answer the local API. Somfy myLink is listed obsolete on the Somfy store. Motors are ordered through Somfy dealers and shade fabricators rather than retail, so several of the links below are manufacturer product pages rather than storefronts.
