@rich_l_oliver It seems like you’re having some challenges with the mounting bracket for your Aqara Valve Controller T1 on your main water line. Based on the reference information, the mounting bracket provided is suitable for pipes up to a maximum DN20 size, and if there’s a large gap during installation, inserting a rubber gasket on the outer side of the pipe before securing it with the bracket is recommended. However, if the standard options aren’t suitable for your setup, exploring modifications or custom solutions might be necessary.
Unfortunately, our current resources don’t include specific suppliers for modified brackets. I recommend reaching out to the community for any DIY solutions or local suppliers who’ve tackled similar challenges. Your initiative in finding a solution could help others facing the same issue.
