Somfy
Somfy motorization that works with Selora and Home Assistant. Nothing is added device by device: a TaHoma or Connexoon gateway holds the io-homecontrol and RTS pairings, and Home Assistant talks to that gateway through the Overkiz integration, over the gateway's local API where the model supports it and through the Somfy cloud otherwise. The protocol a motor speaks decides how much of a shading design can be automated, because io-homecontrol reports real position back and RTS reports nothing at all.

Shades & Covers
6 devicesAltus 40 RTS
Altus 40 RTS is Somfy's workhorse mains tubular motor for roller shutters, exterior blinds, louvres, and projection screens, with the RTS receiver built in. It is everywhere, it is cheap to specify, and it is one-way: Home Assistant can command it but never learns where it stopped.
Glydea Ultra 60 RTS
Glydea Ultra 60 is Somfy's curtain track motor for heavy drapery, quiet enough for a bedroom and strong enough for 132 lb of fabric on a 36 ft run. The RTS version is the one most fabricators ship, and it reaches Home Assistant through a TaHoma, Connexoon RTS, or myLink gateway.
IZYMO Shutter Receiver io
The IZYMO Shutter Receiver io (1822661) is a micromodule that fits behind an existing shutter switch and puts a wired roller shutter onto io-homecontrol without replacing the motor. The existing wall switch keeps working, and the shutter gains position feedback through the gateway.
RecommendedOximo io
Oximo io is Somfy's io-homecontrol motor for exterior roller shutters, sold both on its own and as a retrofit kit that replaces any existing shutter motor whatever brand or technology it used. It reports position, detects obstacles, and is the standard way to bring a house of dumb shutters into Home Assistant one window at a time.
Sonesse 30 WireFree RTS (Li-ion)
The Sonesse 30 WireFree RTS is Somfy's battery interior shade motor: a 12 V lithium-ion pack inside the tube, about one recharge a year, and no cable to pull. It is the answer for a retrofit where running power to a window is not an option, at the cost of RTS being one-way.
RecommendedSonesse 40 io
The Sonesse 40 io is Somfy's quiet 40 mm tubular motor for interior blinds and projection screens, and it is the one to specify when a shade has to be automated properly: io-homecontrol means the motor reports its real position back to the gateway, so Home Assistant reads a position instead of guessing one.
Hubs & Gateways
6 devicesConnexoon io
Connexoon io (1811429) is the small io-homecontrol box Somfy sold as an entry point below TaHoma, with three app personalities for windows, access, and the terrace. It is discontinued, but Home Assistant still drives it through Overkiz over both the cloud and the local API.
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.
myLink
myLink is the North American RTS bridge Somfy sold before TaHoma, and it is the one Somfy product that does not go through Overkiz: Home Assistant talks to it with the dedicated Somfy MyLink integration over the local network. It is obsolete hardware that is still worth supporting, because the installed base is large.
TaHoma Beecon
The TaHoma Beecon is the RTS and Zigbee hub Somfy sells in North America, where it is marketed as the TaHoma gateway under reference 1811731. Home Assistant supports it through Overkiz, including the local API, and treats it the same way it treats a TaHoma switch.
RecommendedTaHoma switch
TaHoma switch is Somfy's current hub and the one to specify for a new install, because it is a multiprotocol gateway that Home Assistant can drive over the local API instead of the Somfy cloud. It ships in two regional variants, and which radios are inside depends on which one was bought.
TaHoma v2
TaHoma v2 is the previous generation Somfy box, superseded by the TaHoma switch but still in thousands of homes. It is worth knowing because Home Assistant supports it over the local API, so an older installation does not have to be replaced to get local control.
