I couldn’t find the firmware file and bought Tuya Multi Mode ZigBee Bluetooth Gateway Hub.
How to update.
Lets see if GX02 will be more stable with new FW. Keep you posted,
You can connect it to Tuya Multi Mode ZigBee Bluetooth Gateway and gateway connected to your network by WIFI, but in this case use Tuya integration. I agree with you, buy it only if you are ready to struggle with troubles 
Hope they will improve this device with our help too
How is it going after some days?
I’m considering buying a Tuya Zigbee Gateway just to update the firmware (and eventually try to sniff the ota url via wireshark).
It’s very unstable, stop responding after a few hours.
Device is connected now to Zegbee amplifier and after update I did not see disconnects. I have not checked if the sensitivity and consumption has improved. The current battery charge is 60% and still works.
To sniff and save OTA image is good idea. Second idea, what I have, is to find this file in Android file system, finding the file in IOS is going to be an impossible task.
Works fine for me, please see below Irrigation Dashboard using this device.
Yeah… but you are also using a Tuya Soil sensor that is rubbish in my experience 
Last year I used the giex with solarpannel build in (around 50 euro on Ali now). Works great, but can’t deal with frost…
So… how’s this device with the newest firmware? Working?
The one i have now is connected to z2m, but I am unable to control it. The device just doesn’t respond…
Mine seem to be working fine. Time will tell.
Mine, after updating it to last firmware, is much more stable and working well, despite the limited distance. I’m currently using z2mqtt
Hey - I purchased the hub and updated the FW of two of my valves to 1.0.13. However, now it seems I can’t get them to pair with zigbee2mqtt anymore. Is anyone experiencing the same?
I just bought GX02 and updated it to 1.0.13. Zigbee2mqtt now shows this in logs and the device is not working:
(unsupported device)Device ‘0xa4c13855ef78b0f8’ with Zigbee model ‘TS0601’ and manufacturer name ‘_TZE284_7ytb3h8u’ is NOT supported
not sure what to do
Have you tried several times? I get this error too but the second time I paired it worked perfectly.
yes, I tried 3 times. No luck.
It seems ‘_TZE284_7ytb3h8u’ is a different footprint. according to this, the next release of Z2M should get rid of the error message. Judging by the release periodicity, this could drop any day…
PS: What’s the difference between GX02, QT06 and QT06_2? I ordered a GX02, but after the update to 1.0.13 (through an extra tuya gateway I bought) it identifies as this ‘_TZE284_7ytb3h8u’ which according to the devbranch of z2m is a QT06_2…
Z2M v.1.39.0-1 just got released:
Fixed device detections:
_TZE204_a7sghmms as Giex QT06_2 (@ayasystems)_TZE284_7ytb3h8u as Giex QT06_2 (@Koenkk)_TZE204_4fblxpma as GiEX GX02 (@Oggymator)I just updated the firmware of my two, and will see how they go. To prevent overwatering, I always set the duration of the watering period on the device before turning the water on - that way if there was any drop out, or home assistant restarts etc, it would be controlled by the device.
Essentially, whenever the Smart Irrigation calculated a new watering duration, it would be sent to the valve.

Yes, I probably should handle unavailable/unknown errors…
Excellent 
Hello, I think it depens on firmware version.
I ordered two GX02 and they came with firmware v.1.0.8 and had Zigbee Manufacturer_TZE200_7ytb3h8u.
It apperars in Z2M as GIEX QT06_2.
After updating one of them to firmware v.1.0.13, it has Zigbee Manufacturer _TZE284_7ytb3h8u and appears as GIEX GX02.
I just got my tuya zigbee controller yesterday, and was hoping to update the valve. However, 24h later the controller still says there are no updates available for the valve.
It’s running zigbee module v1.0.8 and MCU module v1.0.15.
Am I missing something?
