For what it’s worth, I’ve had mine a couple of months now without any connectivity issues. But it does go through batteries with some regularity.
I wanted to let you know that I also experience the connectivity issues using zigbee2mqtt.
Some posts here indicated that it might be a ZHA specific issue but I cannot confirm this. I tried both ZHA and Z2M and both had the same issue.
I would love to learn how to install that firmware update.
Hi all,
I have the same problem of conectivity. I contacted the Giex support and they told me about the new firmware, but it can be only be updated through Smart Life app, so I ordered a Tuya hub to update it and check if that update solves the issues. If not, I will return the valve as it is useless.
I asked them to provide the posibility of updating it through zigbee2mqtt, but looks like this is banned in China and they can’t provide any support for it…
Do you know where to find step-by-step instructions on how to update firmware? do you have FW bin file ?
So far an upgrade is only possible via the Tuya Smart-life app. And you need the GX zigbee hub. They sent me one for free but I didn’t got it yet. Eventually there is a way to extract the firmware file from the app, I will try at least.
If the device is useless without an update, I will open case and maybe I can update the chip plugged directly into it. I will also ask support if they can send me the FW file. My experience is: if you buy devices from china, you’ll have to dig into them yourself. I am ready 
P.S. ZHA OTA Firmware Update / Upgrade
Seems we need only to find BIN file.
im sorry i have a _TZE200_a7sghmms GiEX QT06, only on off in ZHA, is there any way to add other entities? with ZHA
I finally managed to update the firmware with a Tuya Hub, and surprisingly the device is now working (just 24h testing) and the range is improved, I can connect it from 5m long.
The firmware version was upgraded from V1.0.9 to V1.0.13.
I will keep testing it few more days.
zha or zb2mqtt?
With zb2mqtt
Is it possible to store FW file some how ?
no idea… I just updated it with the Tuya Hub, I saw no option to store it in the app
I think 100% it must be stored in some temporary folders. To update directly from network is very bad idea
I can’t find the file, either the temp folder… any idea where it can be stored?
If you have android, it is easier and you can just search for all files with the extension by the following template
*OTA*.bin
The name of the template is just my guess.
Hi all. I bought one GX02 valve in April 2024, added it to HA via zigbee2mqtt, everything works fine.
In May, I purchased 2 more GX02 valves and these valves are not added to HA with the following error.
Device ‘0xa4c1389999125c6d’ with Zigbee model ‘TS0601’ and manufacturer name ‘_TZE200_7ytb3h8u’ is NOT supported, please follow Support new devices | Zigbee2MQTT .
Any ideas?
I tried, but I found nothing… maybe it is a protected folder (I’m not root)
I have got answer from support, they would not share with us FW file for OTA update. It is another one “advertising” for such kind of devices 
I’m thinking of buying one and integrating it with my Zigbee2mqtt. I can’t find the dimensions of this device anywhere. Could you guys help me out? Thank you
I continue not getting any entity related to any control.
I’ve done the followed the procedure and configured the following on the lines on configuration.yaml
“”"
zha:
database_path: /config/zigbee.db
enable_quirks: true
custom_quirks_path: /config/zha_quirks/
“”"
and on the file ts0601_valve.py i edited line 384 (and it’s not 385)
“”"
MODELS_INFO: [(“_TZE200_sh1btabb”, “TS0601”), (“_TZE200_a7sghmms”, “TS0601”), (“_TZE204_7ytb3h8u” , “TS0601”)],
“”"
I’ve restarted HA and every time I add my new GIEX02 I just get firmware information and LQI and SSI as unknown.
Can anyone help me?
