"Does Overkiz work without internet when connected to Home Assistant?"

"It depends on the integration type. Many Overkiz devices support local control through Home Assistant, meaning basic on/off and brightness work without internet. However, some features like firmware updates or voice assistant integration may still require cloud connectivity. A managed Selora setup prioritizes local control wherever possible."

"Can I mix Overkiz with other lighting brands in Home Assistant?"

"Yes. Home Assistant is brand-agnostic — you can control Overkiz alongside Philips Hue, LIFX, WLED, or any other supported lighting system from one dashboard. Automations can span brands, so a motion sensor from one brand can trigger lights from another."

"How many Overkiz devices can Home Assistant handle?"

"Home Assistant itself can manage hundreds of devices. The practical limit depends on your network infrastructure and the communication protocol (Overkiz uses). A professionally designed network avoids the congestion that causes devices to become unresponsive."

Popular Integration

Lighting Security & Cameras Climate & HVAC Locks & Access Shades, Blinds & Covers Network & Hubs

The Overkiz integration connects Somfy, Atlantic, Hitachi, and other brands that use the Overkiz IoT platform to Home Assistant. This primarily covers Somfy motorized blinds, awnings, pergolas, and garage doors, as well as Atlantic heating systems.

Overkiz communicates through a cloud API connected to your Somfy TaHoma, Connexoon, or other Overkiz-based gateway. Home Assistant can control all devices paired to your gateway, enabling sun-tracking shade automation, scheduled cover positions, and coordination with climate and lighting systems.

Common Overkiz Issues

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

Cloud-only communication

All commands route through Overkiz's cloud servers. Internet outages or Somfy cloud issues make all covers uncontrollable through Home Assistant. Physical remotes continue to work as they use local RF.

Command rate limiting

Overkiz's API limits how frequently commands can be sent. Rapid position adjustments (like sun-tracking every 5 minutes) can hit rate limits, causing commands to be silently dropped.

Position reporting inaccuracy

Somfy motors estimate position based on runtime rather than actual measurement. Over time, reported positions drift from reality, requiring recalibration.
