Found a box of new MYGGSPRAY motion sensors at ikea tonight, it was $9.99 (vs vallhorn ~$15). They also had in stock the new matter water sensor, I should have, but didn’t grab one.
Both of these devices have a yellow lid on the otherwise white cardboard box, so I assume that will be a quick way to identify the matter stuff vs the legacy zigbee devices.
HA thread about the ikea matter stuff @ IKEA just announced 21 new affordable Matter-over-Thread smart home devices
They are one of the new matter over thread ikea devices. This is my first matter/thread device.
They are very similar physically to the vallhorn, but not quite the same, they are round instead of square and have a white led indicator outside the sensor, instead of the red inside the dome of the vallhorn.
It does not have any visual/led indication of when motion is sensed.
It comes with (what appears to be) a device specific qr code on the booklet, and inked into the side of the device, which will normally be covered by the cover/mount that snaps on the back like the vallhorn. It came with 2 small 3m sticky pads. Like the vallhorn, the battery cover comes off and there is a single physical button, which I assume is to reset it. I did not find any details about that button in the included setup info. it does not have the extra buttons for changing the occupancy delay and luminescence mode that the vallhorn does.
I put 2x ikea aaa batteries in it and it appeared to go into pairing mode automatically, with the led flashing.
I onboarded easily with my old iphone 8+ to home assistant, via home assistant app and the qr code. It was found immediately and took about a minute or so to pair, then prompted for a device name, and was added to HA successfully with no apparent issues.
The motion sensor seemed to work as quick or maybe quicker than the vallhorn, might be dependent on the size and RF cleanliness of your networks of course.
My matter setup had already been setup previously with a HA skyconnect/zbt1 in thread mode, t0bst4r’s matter hub integration/addon, the HA matter server, and the open thread border router addon, but this is my first actual matter/thread device. I have a couple apple mini’s and a google home as other connected matter controllers.
The device name that I entered when I was prompted for, did not seem to make it into, or change the HA device name, the default is apparently MYGGSPRAY wrlss mtn sensor.
I have attached screenshot of the HA device page with default sensors and diagnostics. It has 2 ‘identify’ buttons, but they both appeared to do the same (flash the led for about a few seconds), battery status, type, and voltage.
I will be testing out the reliability over time and post back with any interesting observations. LMK if any questions, I will try to answer.
