Tricky to install on our main1/4 turn water valve, perhaps because it’s diameter is larger than most water valve. It was difficult to secure without the valve tilting. >> A valve with two attachment points would work better.
Additionally, once installed, it would not connect to the camera hub G3. >> you first need to update the hub firmware through the Aqara App (Profile > Firmware Update). This will allow you to connect the valve to the hub. Then you can update the firmware of the valve. Once done, it worked fine. ** Aqara should provide a note in the box or in the instructions manual that firmware updates are required, as I lost valuable time finding this out.
Surprisingly strong mechanism by Aqara as our valve is not that easy to turn.
