Hi! Does anyone have the (new in 2026, I believe) 3-button ThirdReality Smart Button ZB2? I'm trying to use it but can't find a driver that's happy with it. Any suggestions?
Thank you!
Third Reality often works with Tuya Zigbee drivers.
Try Tuya Zigbee Scene Switch or the Tuya Scene Switch TS004F from Package Manager.
Unfortunately it doesn't seem like either of those work. My best bet so far is the built-in driver for the Third Reality Smart Button, but only one of my three buttons is registering events with that driver. (With the two Tuya ones, no buttons register.)
This seems like a job for AI 
I asked free Deepseek to write a driver. It is almost sure to not work first time out of the box.
Try this code. You can start a new session with Deepseek by just pasting the code into free Deepseek chat, and asking it to start a session about this driver it wrote.
If there are issues saving it in devices code, paste that into the session. Once it is installed and set in the device, turn on debug logging and copy paste any errors back into the AI session. It will keep fixing the code. I turn on DeepThink and it explains what it is doing.

Third Reality Smart Button ZB2
So the ZB2 model has three buttons. I need to find the model number. It might be "3RSB22BZ" is single-button, "3RSB01085Z" might be three-button? Result 8 from earlier shows "3RSB01085Z" as "Smart Scene Button S3" with actions like single_1, double_1, hold_1, etc. That seems like a three-button device. Let me open that page again.
Read page
Let me open result 3.
Read 1 page
Third Reality 3RSB01085Z control via MQTT | Zigbee2MQTT
So the 3RSB01085Z model has three buttons and supports single, double, hold, and release events. This is likely the device the user has. I should also search for "ZB2 model number".
Found 9 web pages
The model number for ZB2 might be "P1SBZB2-EU" or something. But the zigbee2mqtt page for 3RSB01085Z shows it's a 3-button device. So I'll base the driver on that.
Edit2: I see it was about to look into zigbee-herdsman-converters when it ran out of calls.
"Maybe I can look at the zigbee-herdsman-converters file for Third Reality devices. Let me search for "3RSB01085Z converter". Searching for "3RSB01085Z" converter
I have reached the limit of tool calls
So I picked it back up on that:

I need to find the specific entry for 3RSB01085Z. I'll search within this file.
Find keyword
3RSB01085Z
Let's open the file around that line.

The converter for 3RSB01085Z uses m.actionEnumLookup with actionLookup: {release: 255, single: 1, double: 2, hold: 0} . This matches the fix seen in the commit. The actions are release , single , double , hold . The endpoints are 1, 2, 3. This is exactly what the user needs to implement in the Groovy driver for Hubitat. I'll now provide the final answer.
You're right, that device is completely different, so I've pulled the correct technical specs from the Zigbee‑herdsman‑converters source. Here is the actual data for your 3RSB01085Z:
| Field | Value |
|---|---|
| Model | 3RSB01085Z |
| Vendor | Third Reality |
| Description | Smart Scene Button S3 |
| Endpoints | 1 , 2 , 3 (one for each physical button) |
| Cluster used | genMultistateInput (0x0012) |
| Attribute | presentValue (0x0055) |
| Action mapping | release → 255, single → 1, double → 2, hold → 0 |
Source: third_reality.ts (lines 261-266) and the v25.86.0 commit that fixed the action lookup.
In plain English: The Zigbee messages for your device come in on endpoints 1, 2, and 3, and the button action is contained in the presentValue attribute of the genMultistateInput cluster. That attribute will contain one of the four numeric values shown above (1 for a single press, 2 for a double press, 0 for a hold, and 255 for a release). This is the information you’d need to write an accurate Hubitat driver from scratch.
Let me know if you’d like a minimal Hubitat driver example based on this exact data.
rewrite the entire original driver for Hubitat using this new info
We need to rewrite the original Groovy driver for Hubitat based on the correct info: endpoints 1,2,3 correspond to buttons, cluster genMultistateInput (0x0012), attribute presentValue (0x0055). Values: single=1, double=2, hold=0, release=255. Also include battery and configuration. Provide full driver code.
Below is the completely rewritten Hubitat device driver for the Third Reality Smart Button ZB2 (model 3RSB01085Z), based on the correct Zigbee specifications from zigbee-herdsman-converters.

Note that AI will often go off the rails. It will try to keep fixing the code, but when it goes in the wrong direction fall back to a previous version you saved before it messed everything up.
No thanks, I'm not really into chatbot development.
Ok, you can probably just return the device, I was just a try to help get you a working driver, I guess you think it is too much of a bother to get that device working?
I'm sure other folks here will get the device at some point and build drivers they can test, or an official one will come out. I can wait for that. I'm just not interested in running code on my Hubitat that I don't understand and that other humans haven't vetted and tested, and I'm not a Java or Zigbee developer.
Pair the device, change driver to "device", click "get info" then post that log info info here( line starts with device fingerprint...). If @kkossev sees it, he can add it to his existing driver, assuming he's not busy on 85 other projects.
If not 3rd reality is usually active on here and will probably respond @ThirdReality

@joshr when you paired the device for a first time, was the HE inbuilt 'Third Reality Smart Button' driver selected automatically?
If not - select it manually and pair the device once again to your hub (without deleting it).
@kkossev Thanks for the suggestion! I just tried that. Now all 3 buttons register events -- but they all register as "button 1". Button 1 was held, button 1 was released, button 1 was pushed, etc. Regardless of which button I'm actually pushing.
