Wyze sensors

Wyze, the company whose $25 cameras have become enormously popular, recently released contact and motion sensors. Like the cameras, they're dirt cheap. Two contact sensors and a motion sensor in a startup kit for $20. Oh, they've also released smart bulbs.

Sure would love to see some Indigo support for these trinkets!

AFAIK, there still is no public API for any Wyse gear. There may be some reverse engineered stuff that a 3rd party developer could look into.

This one looks like it might work:

I ordered a starter kit to play with.

With a bit of luck, they'll be hacked in a way similar to what happened with the Wyze cameras. That camera project is amazing, BTW.

Keeping an eye on this thread. When Joe starts playing around, good things often follow.

I got the starter kit. Cute little package. Very small sensors.

I plugged it into a USB port, and I think this is it in the System Report:

Code: Select all

Composite Device:

  Product ID:   0xe024
  Vendor ID:   0x1a86
  Version:   1.0c
  Speed:   Up to 12 Mb/sec
  Location ID:   0x14532000 / 50
  Current Available (mA):   500
  Current Required (mA):   100
  Extra Operating Current (mA):   0


But I can't get it to respond using the sample program from the GitHub project above. That program assumes you're using the hidraw driver, which doesn't exist on MacOS X.

So I gotta figure out what driver is going to work with this device.

Standing by...

I could cobble something together with IFTTT and webhooks but local is so much cooler.

I'm making some progress with this. I was able to get the sample code for the Python module above working with an rPi. It doesn't work on MacOS X because the "rawhid" driver isn't present. But then I was able to query the device using the pyusb library. So I'm hopeful I can convert the WyzeSensePy library to use pyusb instead of the rawhid driver.

I could use some info from anyone else that has one of these devices. I need the info represented in System Information.app. I posted a sample of that above.

Go to Apple menu -> About This Mac -> "System Report..." button. Select USB in the left column, then look in the device tree on the right for "Composite Device". Please paste that info in this thread (use the CODE tags).

Will get mine posted on Monday.

Well, this is looking less and less likely. I've now discovered that a user-level program (like Indigo or an Indigo plugin) can't use pyusb to actually "talk" to a USB device on MacOS X. I can query the device registry and find that there's a device out there, but I can't write to it. That's to prevent user programs from writing to random USB devices (like hard drives).

On Linux, there's the hidraw drive which makes any unknown (to other drivers) USB devices available to user programs. This does not exist on MacOS X. So the only way to use this device is going to be to find (or write) a device driver that will claim this device and make it available via /dev/tty* type device.

I'll be looking into the device driver, but that's not going to happen any time soon.

So, the only way to talk to these sensors is to via USB? Doesn't that somewhat limit their usability?

There's a dongle that's USB. It communicates with the sensors via RF.

The dongle is normally installed in their camera, and then the sensors become sub-devices of the camera. All of which uses a proprietary app to control.

If you can talk to the dongle directly, then the sensors become available without the camera or app.

This shouldn't be that hard, if I could find the code for a working device driver. I just don't want to write one from scratch. Apple's docs at that level aren't real easy to follow.

Oh, I see. Maybe the source for the old PL2303 driver might help?

Yes, that will help. Boy it's been a long time since I did C/C++. This is going to be interesting...

I see it doesn't matter now but I have the Wyze bridge in a WyzeCam that's connected to my Mac via USB, but I'm not seeing a composite device in the system report.
