Hello, I just bought an Wiz motion sensor at my local store to control a WiFi power Switch. I planned on doing this in HA as I did see that there was an Wiz integration in Home Assistant. However, now that Im home trying to set things up, it seems that I cant set up the motion sensor unless I have a Wiz bulb (what a joke). Is there no way to hack this device and use it in HA without actually buying a Wiz bulb that I dont want to use?
You probably have to add it via the mobile Wiz app first, in order for it to connect to your wifi network first. Then, hopefully HA will see it via it’s own Wiz integration.
I just got a couple of Wiz motion sensors at half price, cheap enough to just try and play with, but I’m having the same trouble.
I’ve had no issues connecting Wiz light bulbs and switches before - add them to Wiz app then they appear in HA no problem and can control them from HA (only use Wiz app as a setup, no control).
But the motion sensor does seem to be different. Doesn’t appear in HA and doesn’t even show up on my network - Unifi software doesn’t see it at all. Wiz website says it can connect to any Wiz light within 15 metres. Sounds a lot like it’s doing it’s own network thing and not actually using my Unifi network at all.

I was looking at the documentation on this, assuming it’s this motion sensor:
The docs may be found at the very bottom under the Other+ section.
It says it does NOT use WiFi so it must be using either Bluetooth to communicate with the Wiz App or some other proprietary technology. Maybe this is why these units seem to be on sale in many places for 50% off or more.
I have tried and use many motion sensors. The best by far I have are the SmartThings ones. They are Zigbee however, but they offer extremely good range and decent battery life. While they are a bit pricey, they are indeed worth it.

I also got one of this. Interesting that inside it has esp8266 (esp-wroom-02d) and ST soc (STM8L101F3P6) to handle motion sensor. When it sees motion it powers up esp8266, talks to it via i2c. Then shuts the power to esp. I downloaded the original firmware. Then I had to change it to keep esp powered all time through cutting PCB trace and soldering the input of the Ldo voltage to always high. Then I connected output from motion sensor to gpio of esp and used esphome. It works. I need to measure how long batteries will last in such configuration.

Hi @MaksymK , I also bought one of these WiZ Motion Sensors in the hope it would use Zigbee. What a disapointment however.
But reading your post makes me willing to try to adapt the device.
Would you be willing to share your work on these devices?
Perhaps you have some documentation, e.g. on Github or a document, on how you modified it and hopefully with your adapted firmware and some pictures?
It would be a great help for guys like me who want to make use of these devices.
Kind regards, Bert

I would also be interested in this. Could you share in more detail how you approached this?
Much appreciated!
