Hi @ugrbnk,
Thank you for testing! I see the sensor is detecting smoke physically (alarm sounds), but the data isn’t reaching Homey. Let me help you troubleshoot this step by step.
## 
Current Status
Based on your screenshot and description:
- 
Device paired successfully
- Physical alarm works (sounds when you smoke it)
- 
**No data transmitted to Homey**
- Tiles show no alarm status
This indicates the sensor hardware works fine, but there’s a **communication issue** between the sensor and Homey.

## 
TROUBLESHOOTING STEPS
### Step 1: Verify App Version
**Current requirement:** v3.0.17 or newer
Check your app version:
1. Homey app → **More** → **Apps**
2. Find **Universal Tuya Zigbee**
3. Current version shown at top
**If you’re on v3.0.16 or older:**
- Update to v3.0.17+ immediately
- v3.0.17 includes the Tuya cluster handler fix specifically for your gas sensor!
-–
### Step 2: Re-Pair the Device (CRITICAL)
Even if you updated the app, the sensor needs to be re-paired to use the new handler.
**How to re-pair:**
1. **Remove device from Homey:**
-
Go to device tile
-
Settings (
) → Advanced Settings -
Remove Device
2. **Factory reset the sensor:**
-
Press and hold the reset button for **10 seconds**
-
LED should blink rapidly (indicating reset mode)
-
If no LED blinks, try removing battery for 30 seconds, then reinsert
3. **Add device back:**
-
Homey → Add Device
-
Universal Tuya Zigbee
-
Search for: **“Gas Sensor TS0601 (AC)”**
-
Keep sensor **very close** to Homey during pairing (< 1 meter)
-
Wait 30-60 seconds for pairing
4. **Wait for initialization:**
-
After pairing, wait **2-3 minutes**
-
The Tuya cluster handler needs time to initialize
-
Check Homey logs for confirmation
-–
### Step 3: Check Homey Logs
This is crucial to see if data is being received:
1. **Open Homey Developer Tools:**
-
Go to: https://developer.homey.app/
-
Login with your Homey account
-
Select your Homey
2. **Open Logs:**
-
Click **System** → **Logs**
-
Or go to: Settings → System → Logs
3. **Look for these messages:**
```
GOOD SIGNS:
[TuyaCluster] Initializing for type: GAS_DETECTOR
[TuyaCluster] Found on endpoint 1
[TuyaCluster] Tuya cluster found on endpoint 1
[TuyaCluster] Reporting configured
[TuyaCluster] 
DataPoints received: {“1”:false,“13”:false}
[TuyaCluster] Processing DP 1 (gas_alarm): false
[TuyaCluster] alarm_smoke = false
BAD SIGNS:
[TuyaCluster] No Tuya cluster found on any endpoint
[TuyaCluster] 
No dataPoints in response
Cannot find module ‘../../utils/tuya-cluster-handler’
```
4. **Test the sensor:**
-
While watching logs, make smoke near sensor
-
Physical alarm should sound
-
**Watch logs for datapoint changes:**
```
[TuyaCluster] Processing DP 1 (gas_alarm): true
[TuyaCluster]
alarm_smoke = true```
-–
### Step 4: Verify Device Driver
Make sure the correct driver was selected:
1. Go to device settings
2. Check **Driver:** should show **“Gas Sensor TS0601 (AC)”**
3. If it shows something else, remove and re-pair with correct driver
-–
### Step 5: Check Zigbee Network
If still no data after re-pairing:
1. **Check Zigbee mesh quality:**
-
Settings → Zigbee → Network Map
-
Find your gas sensor
-
Check signal quality (should be green/good)
2. **Improve mesh if needed:**
-
Add Zigbee router between Homey and sensor
-
Or move sensor closer to Homey
-
AC-powered devices act as routers automatically
3. **Check for interference:**
-
Move away from WiFi router (2.4GHz interference)
-
Move away from microwave, baby monitors
-
Avoid metal walls/objects between Homey and sensor

## 
DIAGNOSTIC REQUEST
If still not working after all steps above, please provide:
### 1. Device Diagnostic Report
**How to generate:**
1. Go to gas sensor device page
2. Settings () → Advanced Settings
3. **“Create Diagnostic Report”**
4. Copy the diagnostic ID
5. Post it here
### 2. Homey Logs
**After testing smoke:**
1. Make smoke near sensor
2. Wait 30 seconds
3. Copy logs from last 1 minute
4. Post here (or pastebin if long)
### 3. App Version Confirmation
Please confirm:
- Universal Tuya Zigbee version: **?**
- Homey firmware version: **?**
- When did you last update the app?
-–
## 
EXPECTED BEHAVIOR
**After fixes in v3.0.17:**
When smoke is detected:
```
Physical sensor:
Alarm sounds (beeping)
LED flashes red
Homey side:
Device tile shows “ALARM: Smoke detected!”
alarm_smoke capability = true
Flow triggers fire
Notifications sent (if configured)
Timeline shows event
```
When smoke clears:
```
Physical sensor:
Alarm stops
LED back to normal
Homey side:
Device tile shows “OK”
alarm_smoke capability = false
Timeline shows “Alarm cleared”
```

KNOWN ISSUES & WORKAROUNDS
### Issue 1: Delayed Updates
**Symptom:** Data arrives 30-60 seconds late
**Cause:** Tuya reporting interval
**Solution:**
- This is normal for battery-optimized sensors
- Your gas sensor is AC-powered, so should be faster
- If delayed, check Zigbee mesh quality
### Issue 2: First Alarm Missed
**Symptom:** First alarm doesn’t trigger, subsequent ones work
**Cause:** Initial datapoint not read
**Solution:**
- Re-pair device
- Wait 3 minutes after pairing
- Test second time
### Issue 3: Sensor Goes “Unavailable”
**Symptom:** Device shows unavailable in Homey
**Cause:** Poor Zigbee connection
**Solution:**
- Improve Zigbee mesh
- Check power supply (AC adapter working?)
- Restart Homey as last resort

TECHNICAL DETAILS
### How Tuya Gas Sensors Work
Your sensor uses **Tuya proprietary protocol**:
- Cluster: **0xEF00 (61184)**
- Datapoints:
-
**DP 1:** Gas alarm (boolean)
-
**DP 13:** CO alarm (boolean)
-
**DP 2:** Sensitivity setting
The v3.0.17 handler automatically:
1. Detects Tuya cluster on endpoint 1
2. Configures reporting (0-3600s intervals)
3. Listens for datapoint changes
4. Maps DP1 → alarm_smoke
5. Maps DP13 → alarm_co
6. Updates Homey capabilities
7. Triggers flows
### Why Re-Pairing is Important
When you pair a device:
- Driver loads and initializes
- Cluster bindings created
- Reporting configured
- Initial state read
If you updated the app but didn’t re-pair:
- Old driver still loaded
- New Tuya handler not initialized
- No cluster bindings
- No data reception
**Solution:** Always re-pair after major app updates!

## CHECKLIST
Before reporting still not working:
- Confirmed app version is v3.0.17 or newer
- Removed device from Homey
- Factory reset sensor (10s button press)
- Re-paired with correct driver
- Waited 3 minutes after pairing
- Checked Homey logs during test
- Tested smoke detection (alarm sounds physically)
- Checked Zigbee mesh quality
- Verified AC power connected
- Generated diagnostic report
- Copied logs to post

## 
NEXT STEPS
1. **Check your app version** (most important!)
2. **Re-pair the device** (critical step)
3. **Test and watch logs**
4. **Report back with:**
-
App version
-
Log output
-
Diagnostic ID (if still not working)
I’m confident this will work after re-pairing with v3.0.17+. The Tuya cluster handler was specifically created to fix your exact issue!
Let me know how it goes!
