23 years in the making. Finally--reliable room level presence thanks to mmWave

Why not use some of the non spammy mmwave sensors instead?

you have one in mind that's Zigbee, around $20 and work with Hubitat?

I have one of these exact sensors that I bought for testing. It worked great for weeks, but absolutely destroyed my 5ghz wifi at home as they emit 5.6-5.8ghz radio as their means of operation. I was going to live with it honestly, as 2.4ghz worked fine, but after about 3 weeks of installation, my ZigBee radio crashed and every ZigBee device had to be reconnected to Hubitat again. Since it had been stable for years until that moment, I blamed the mmwave sensor and removed it.

[Navat604]

Thank you for the good infos. I was looking into the Aqara FP2 but just couldn't stand the size and price right now. But then again, my ring motion sensors are also huge...

@ddalder

As much as the Aeotec TriSensor has given me a lot of grief,

What kind of grief? I have one and love it.

The 24ghz mmwave sensors are above $20. There is a thread on the forum with a discussion on 24ghz sensors.

The OP should open up one of their sensors and take a photo of the mmwave board. There is a good chance they are 5.8ghz and not 24ghz. 5.8ghz is microwave.

Here is my computer WiFi antennae within three feet of the device.

Wifi seems to be unaffected...

@a.mcdear

my ZigBee radio crashed

I was also having the zigbee crashing issue in this thread.

No one could ever confirm a cause. I now have more of these sensors than previously. My zigbee network still goes down occasionally. 3 times Tuesday, 2 times yesterday, and 0 times so far today, but it comes back up in 14 seconds since I updated to *.152

1. Seems like they work.
2. They cost $20.

@ddalder

The sensor you're using, ... looks dreadful. A big emblem on the front...

A white label (sticker) could fix that. I'm more concerned about the cords. I'll be adding wire track for esthetics once I am sure that they are all in the best locations.

I have one that I fried with a nonstandard micro usb cable.

Here is what the inside looks like...

void any warranty

Bought from China. I don't think that there is a Chinese word for warranty.

There actually is:

Good Luck

[JumpJump]

Thanks. These are 5.8ghz and not 24ghz. They are microwave and may or may not have issues with sensing through walls too far. These have trouble with some of the micro movements that 24ghz sensors can pick up.

[Ken_Fraleigh]

The 24GHz ones are $29 on Amazon last I checked. Although if it ain’t broke…

[JumpJump]

That Linptech is one of many options for a zigbee 24ghz sensor.

[a.mcdear]

I have one back in AZ ready for me to tear open like a kid having a birthday. (The Linptech, that is) Tomorrow's the day.

[danabw]

If this is true about the Linptech, that's pretty impressive.

One on the way to play with, the easy overnight via Amazon pushed me over the edge.

Plus they were offering a 10% off coupon, so I've saved billions!

Please report back.

[danabw]

Will do...need to determine which driver is the correct one for this device.

@kkossev or @JumpJump or @Ken_Fraleigh - can you help w/which driver?

I'll put the images here for easy reference. For those wanting to change the case on this device it looks pretty simple to bypass the USB socket and wire a pigtail to the board. It would not be hard to get power out the back side. [image] [image]

[pomonabill220]

DAMN YOU!!! I just ordered 5 with 1 of them discounted.
I have places that I can use these, and of course, 30 days return if they don't work.....

[JumpJump]

Great. Looking forward to more folks in the other thread so we can share.

Damn! Those are even cheaper...

These are BlueTooth !
Beware as they look exactly the same as the Zigbee version.
