Remove the cover (I used a dull table knife in the slot turning counter clock wise, it has strong magnets holding the cover), then factory reset by pressing and holding the raised reset button 3 seconds per microprint in the instructions, then reinstalled the cover.
Then started zigbee pairing while pressing button, and it automagically paired. In other words I'm not sure why it paired after the factory reset.
I did find a lot of information about the button by searching github for
ZS232000178 and "linkind button". Perhaps you will understand it.
Got mine to pair with the Hubitat, used @arnb notes above, a little tricky, got to watch how you hold the reset button down without pressing the overall button, didnt need to reinstall cover to do it.
NVM - Got it! @mike.maxwell - Below is the secret sauce:
You have to ever so lightly press the reset button but NOT make the full button do a normal button press event while holding the reset button. Then the red LED starts blinking very quickly and it joined my hub very easily.
Clearly I have too much free time this morning (wife is sleeping in) and I'm playing around w/other button drivers I'm finding...tried the Konke driver that @arnb posted about above, and interestingly I can control button events from the device page (I set up an ABC automation to toggle a light).
However, pressing the button does not work to run the automation, but tapping the Push command does.
Logs - the button press events are from the Push commands on the Device page, the physical button presses aren't showing up in the logs and don't toggle the light.
Tapping/Clicking the command on the device page executes the routine normally associated with a physical event occurring on the device. So that will work as long as it does not send a response to the device.
As noted by @danabw, others, and myself, the button's parse routine logs nothing when the button is pressed, leading me to believe these buttons are doing something unusual. When operating as standalone devices tied to a bulb or plug, they likely act as if they are a hub, issuing commands targeted to the respective paired device rather than being a button and sending a command to a hub. No idea what they do when paired with a Linkind or HE hub, but my gut says it may "know" when it's paired with a Linkind hub.
Hopefully this can be deciphered and understood by @mike.maxwell.
Got two on Amazon with a 30% off coupon for around USD $8.80 each with tax and shipping. Paired immediately and work well. They are sold out on Amazon but remain available on the Linkind website for about USD $10 each. According to site: free shipping and no tax. Also shipping to EU and GB
My Linkind contacts paired as generic zigbee contact sensors with temperature reporting. They work great, but don't report temperature, and there is no Linkind Contact driver that I can find. Am I missing something?
Be careful what you promise, Unless HE are planning on releasing a platform update before Christmas, her new button may more likely be a New year's present.
The Factory Reset was a good tip. When I did that, the LED went solid red, then flashed Rainbow, and joined the C7 immediately as a Generic Zigbee Outlet.
Bad news for now, the button will not work currently, it is only capable of emitting broadcast commands which the hub currently doesn't process.
This is the same sort of issue that exists with some of the Ikea controllers.
We may look at supporting these types of commands in the future, but right now we don't.
Thank you for trying Mike, unfortunately my gut feeling was correct. As you said, perhaps in the future. I still believe the device may "know" when it's connected to a Linkind hub and act like a normal button.
Thank you @mike.maxwell for looking at these, hopefully sometime in the future your team can get these working, the Hubitat system is truly amazing at what it is capable of doing.
