LinknLink eMotion Ultra Review: HA Floorplan Setup & MQTT Presence Detection

Unboxing: Checking out the eMotion Ultra, the new magnetic stand (big improvement), THS cable, and door/window sensor.

App Setup: Adding the device to the LinknLink app, connecting WiFi, and updating firmware.

Sub-devices: Configuring the presence sensor, light sensor, and temp/humidity sensor within the app.

MQTT Integration: Enabling MQTT in the app to connect the sensor locally to Home Assistant.

Home Assistant Dashboard:

• Floorplan Setup: Using the picture-elements card to create a visual floorplan.

• Conditional Elements: Configuring images to light up rooms (green) when presence is detected.

• Code Editor: Using YAML copy-paste for faster setup of multiple rooms/floors.

Door Sensor: Adding a door sensor icon to the floorplan and scaling it up for visibility.

Conclusion: The eMotion Ultra is a "real step up" from the Max, praising the new stand and all-in-one sensors (IR, Light, Temp/Humidity) as a high-end solution.
