Can Home Assistant track the sun to adjust Somfy MyLink shades automatically?

Yes. Home Assistant has built-in sun tracking that calculates the sun's azimuth and elevation for your location. Automations can adjust Somfy MyLink shade positions based on these angles — closing shades when direct sun hits a window and opening them when it passes. This requires careful configuration per window.

Can I still use the Somfy MyLink remote after connecting to Home Assistant?

Yes. Most motorized shade systems continue to respond to their original remotes alongside Home Assistant control. The physical remote always works as a fallback, even if Home Assistant is offline.

How much energy can automated shades save?

Automated window coverings can reduce cooling costs by 15-25% by blocking direct solar heat gain during peak hours. Combined with climate sensors, Home Assistant closes Somfy MyLink shades precisely when they make the biggest impact.

Somfy MyLink & Home Assistant

Shades, Blinds & Covers Network & Hubs

The Somfy MyLink integration drives a myLink bridge over the local network using Somfy’s Synergy API, and it is the one Somfy product that does not go through Overkiz. Every RTS shade, blind, awning, or shutter paired to the bridge becomes a cover entity in Home Assistant, with no Somfy account and no cloud in the path.

Setup is a config flow that asks for the bridge’s address and its system ID. myLink is obsolete hardware, replaced by the TaHoma switch, but the installed base in North America is large and integrating an existing bridge locally is usually a better outcome for the client than replacing it.

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.

How Somfy MyLink Works with Home Assistant

Getting Somfy MyLink connected to Home Assistant and running reliably.

1

Connect & calibrate

Add Somfy MyLink through the integrations panel. Motorized shades and blinds appear as cover entities with position and tilt control.

2

Position & tilt control

Set exact positions from fully open to fully closed. For blinds with tilt, adjust the angle to control light direction precisely.

3

Sun-tracking automation

Build automations that adjust Somfy MyLink based on sun position, room temperature, or privacy schedules. Home Assistant calculates solar angles to optimize natural light.

Common Somfy MyLink Issues

The problems installers run into with Somfy MyLink and Home Assistant — and how a managed setup prevents them.

Every cover is assumed state

RTS is one-way radio. The bridge transmits open, close, and stop, and no motor answers, so Home Assistant cannot track where the shade actually is. Where a dashboard needs to show open or closed, that state has to be held alongside the cover, typically in a template cover, and it is only ever as right as the last command that got through.

Covers can arrive reversed

A motor programmed or wired in reverse presents as open when it is closed. The integration's options let you flip individual covers, which is the fix; doing it at the motor instead means a service visit per shade.

Addressed by IP, with a system ID

The bridge is referenced by address and authenticated with its system ID, so a DHCP lease change silently breaks every cover until the entry is reconfigured. A reservation on the bridge is the first setup step, not an optimization.

Obsolete hardware with no successor firmware

Somfy lists myLink obsolete and points new work at the TaHoma switch. Nothing new is coming for the bridge, so a failure is a migration rather than a repair, and the RTS channels have to be re-onboarded onto the replacement hub.

Why installers choose managed myLink setups

Bridge on a reservation and monitored, so a lease change is not diagnosed as broken shades
Cover directions verified per shade once, rather than found by the client one room at a time
Scenes designed around assumed state, with real position sensing added where an automation needs it
A documented migration path to a TaHoma switch, ready before the bridge fails rather than after

Altus 40 RTS

Somfy

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

Somfy

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.

Sonesse 30 WireFree RTS (Li-ion)

Somfy

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.

myLink

Somfy

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.
