A WiFi controller that plugs into your Ewelift actuator board and gives you Home Assistant integration, MQTT, and a local web UI. No cloud, no subscription, no vendor lock-in.
The controller taps into the Ewelift control board’s RJ45 port, communicating over UART to send movement commands and read the actuator’s real-time position. It draws power directly from the same connection — no separate supply needed.
It mounts above the ceiling line next to the existing actuators. No visible hardware, no wall panels to replace. Your rooflight looks exactly the same — it just got a lot smarter.
Speaks the Ewelift serial protocol natively. Sends movement commands and reads real-time actuator position over the existing RJ45 connection.
Publishes as a Home Assistant cover entity with position reporting. Works with any MQTT broker — Mosquitto, EMQX, whatever you run.
Built-in responsive control panel served directly from the controller. No app, no hub, no account. Open a browser and control your rooflight from any device on your network.
Check off the components in your rooflight system. You need all three to be compatible.
Yes. Everything runs locally on your network. The controller hosts its own web UI and communicates with Home Assistant over your local WiFi. No cloud, no external servers.
No. The controller plugs into the existing RJ45 port on the Ewelift control board. No cutting, soldering, or permanent changes.
Yes. It publishes as a cover entity via MQTT with auto-discovery. You get position reporting, open/close/stop controls, and can use it in automations.
The controller replaces the 5-button wall switch. Your remote control continues to work as normal.
Your remote control still works. The controller will reconnect to WiFi automatically when it’s back.
Via the RJ45 port on the Ewelift control board. It communicates over UART at 9600 baud to send commands and read the actuator’s position.
No. It draws power directly from the Ewelift control board through the same RJ45 connection.
Yes. The controller runs a built-in web UI accessible from any browser on your network. No app to install.
It mounts inside, above the ceiling line next to the actuators in the roof void. It’s not exposed to weather.
Check for an Ewelift control board with an RJ45 port. Tested with the NKCB12-Y; other NKCB models may also work.
Yes. It’s a single cable connection — plug into the RJ45 port and you’re done. No electrical work required.
