I've been chasing this mythical Tuya Zigbee Smart Knob for more than 3 months now.
And I am still in doubt if it really exists! 
I put 4 orders to 4 different AliExpress sellers, I've got 3 refunds so far, still waiting to receive it from the 4th seller 
Outside of that Smart Knob being THICK .. it looks awesome
Do you have it?
I do not .. just found this thread today. But I want it
What I am afraid of is that these may use the same Zigbee inbound group messaging that are not supported by HE and prevent IKEA and LIDL remotes to be used here... But let's hope we will understand soon,
OK mine was ordered beginning of January and apparently its now on a plane....we will see.
I managed to get one of the smart knobs. It will pair with HE but after that no more events are captured by HE. Well mostly, I did have it sending events for button pushes briefly. I know nothing about zigbee protocols or messaging so now it waits until I feel like I could learn about it.
@bbholthome can you try this ~~experimental driver?
First, change the driver manually, then pair the knob again to HE.
You can send me the logs in a PM to avoid spamming this thread with technical data.
Try the driver from the link above.
It should handle the single, double and held key presses. Clockwise rotation should generate a button 2 pressed simulated event, Counter-clockwise rotation should be button 3.
Seems like this is all that can be done when paired to HE for now.
Yep that's all working, shame that it's not quite what I was expecting.
Is it a Hubitat or driver limitation do you know?
What were you expecting?
I thought that it was going to allow me to dim lights, but now I'm writing this I'm thinking it will as I could set each button press 2 increase by 1% and button prss 3 decrease by 1%.
Just going to try that now
And just like that out of the junk draw and in action, not quite as smooth as my fibaro dimmer 2s but it works well enough.
So push and rotation doesn't work not a biggie, But is this possible????
Any clue if these are standard Zigbee 3.0, or ?
Zigbee 3.0
You can experiment with 10% or even 20% increase/decrease, that may work better. What is the minimum time between two rotations in the same direction (clockwise or counter-clockwise) that generate events? I expect to be around 1.2 seconds, i.e. faster rotate rate will not generate new events?
It is not possible now. We must wait for HE engineers to implement the missing inbound group messaging processing in HE hub, that still seems to be not a top priority in 2022 (see this link)
Zigbee specification document is 565 pages, I can't tell.. 
But again, this is a HE limitation, that prevents some IKEA and LIDL and also Tuya remote dimmers to have the full functionality in Hubitat. At the same time, these remotes work with HomeAssistant ZHA, zigbee2mqtt and even with SmartThings hub... This has been discussed in many threads in the past.
Thanks - Wasn't aware about SmartThings. Do you mean Tuya devices in general play nicely w/SmartThings, or were you referring the knob device in particular. I have a SmartThings hub that is sitting pretty much idle. Could be an option to share Tuya devices from ST to HE.
A lot of Tuya Zigbee devices use Tuya specific clusters, so there is no native support for these in any home automation platform (except Tuya own Zigbee hub), until a custom driver is written for it.
I wouldn't say SmartThings has better support than HE for Tuya devices, probably the only exception is the above-mentioned possibility ST to handle remote dimmers broadcast packets (StepUp/Step Down).
Technically, this is what we are talking about:
I am not aware of any other Tuya devices that are supported by SmartThings, but not in HE. If such devices are found, it can be easily corrected The only exception are functionalities related to these inbound group messages.
Hi ! Is there any update to this topic? I tried clicking the link to the experimental driver but it sends me message 404 not found. Thanks!
I have edited the link to point to the driver release thread.
What works with this smart knob is the singe and double click and left/right rotation.
