IKEA VALLHORN motion sensor (ZHA)

Hardware
5

Hi,

This is just to confirm that vallhorn from Ikea works pretty fine, at least for me.
Setup is:

  • 2 x vallhorn motion sensor, each equipped with 2 x Ikea Ladda 750 mAh AAA size accu

  • haos running on a virtualbox machine, the hass.io virtualbox image itself

  • Sonoff Zigbee 3.0 USB Dongle-E, installed in the PC front panel USB 3.0 port

  • use USB Filter to make Sonoff available for the VB machine (Fig 1)

  • no USB-A to USB-A extension cord for the dongle just because I ordered it yesterday and it did not arrive yet

  • running Zigbee Home Automation (Fig 2)

This one detects the Sonoff dongle, then in integration/zigbee home automation/1 device/zigbee coordinator you get to “Add devices via this device” (Fig 3)

When getting there, ha is looking for your zigbee devices. (Fig 4)

In order to add these vallhorn things you need to push the vallhorn device link button 4 times in max 5 sec, as stated by device’s specs to factory reset. They’ll be then found and added to your devices list. Don’t push the link button for “at least 10 seconds” - Ikea advice, I think you have better things to do with your time.

A vallhorn device presents these properties: battery status, identify (pushing this from HA will make the sensor flash reddish for a couple of times), illumination level (at device level), opening (sdfjbg), occupancy (motion detected).

Do not use the default blueprint named “Motion-activated Light”, just create an automation from scratch, it simply works.

Good luck!
