I have 3 Fingerbots at present. Two Fingerbot Plus units and one Fingerbot. I discovered that there are MULTIPLE companies selling HW identical devices called Fingerbot. So the initial product I ordered wasn't an Adaprox one, and there is no documentation that would let you know that clones abound. Searching on Amazon easily brings up devices called Fingerbot which are not from Adaprox.
Then I discovered there are at least 3 apps you can onboard these devices with.
The Adaprox one, SmartLife, Tuya Smart, (you also have some level of access via Tuya Developer). You can onboard on any of them (but you've got to reset between each).
Trying to bridge to Apple Homekit is confusing as all heck, because there are multiple web pages that describe how to do it for all the apps, though it seems that somehow Tuya is be the main source of truth. But I've tried them all, and at present I still can't get any of the bridge
descriptions to work (via HomeBridge).
There needs to be SOME PLACE for real, tested, and working instructions for this. And SOME documentation to say that this design is apparently "OPEN" and that multiple companies have manufactured these devices.
Second, it comes with only one "tip" that can fall out of the device if you're not careful.
And this tip isn't necessarily long enough to push a good number of buttons. I had to pay extra for the add on kit (though I've seen seen that there are also 3-D designs, not sure the author, that you also can print). But the add on set of tips SHOULD COME STANDARD.
