Quick Start

Pre-release documentation. CeilSense V2 has not been officially released yet. The design, specifications and firmware can still change until release. Check ceilsense.nl for the current planning.

This is the shortest route from box to Home Assistant. The Installation Guide has the full details for the ceiling, the cables and the first start.

Safety: Have mains connections made by a qualified installer and switch the circuit off first. CeilSense V2 is IP20, for indoor use only.

What You Need

  • CeilSense V2 base with your radar and, if you chose it, the SCD41 module
  • Power: a USB-C supply (5 V, at least 1 A, not included), a PoE switch or injector (IEEE 802.3af), or a mains connection made by an installer
  • A 2.4 GHz WiFi network or an Ethernet connection
  • Home Assistant
  • Firmware that matches your network choice and modules. Firmware and install steps are published at release: see Firmware.

Steps

  1. Fit the modules. Skip this step if you chose the assembly service. Disconnect all power first and follow Radar and Sensor Modules.
  2. Power it on the table. Test the device before it goes into the ceiling. Connect USB-C, or PoE if you use it. The LED ring stays off and the buzzer stays silent during start-up. That is normal.
  3. Connect it to your network.
    • With WiFi firmware, connect your phone or laptop to the network CeilSense V2 Setup. Choose your own 2.4 GHz WiFi network in the captive portal and enter the password.
    • With Ethernet firmware, connect the network cable.
  4. Add it to Home Assistant. Go to Settings > Devices & services. ESPHome devices are discovered automatically: select CeilSense V2 and add it. If it does not appear, see Network Configuration.
  5. Check the entities. Open the device page. Presence should change when you move in front of the radar and Illuminance should show a value. Switch on LED Ring and press Buzzer Test. With the SCD41 module, CO2 updates every 30 seconds.
  6. Mount it. Disconnect the power, make the Ø 76 mm cut-out, connect your cable and push the sensor in. The spring clips hold it against the ceiling. Follow the Installation Guide.
  7. Tune the radar. With LD2412 + LD2450, empty the room and press LD2412 Start Dynamic Background Correction. With an LD2460, do the walk test. Both are explained in Calibration.
  8. Build on it. Create your first automation, or add the optional SmartHomeShop.io integration for the Room Designer and the CeilSense card.
