For 4 years he diced cold rains or is my portal begins to m ***. My installation is fully compliant yet. The electronic box ended up downright crashed and Somfy sent me a new one free plus a box (not waterproof!). Installation of the new case and complete review of the facility. After 2 months of new problems, so do not waste your money and your time trying to make repairs, it is useless, this is a design problem. I am studying the issue, but I think I'll try to put a simple opening manual. I'm not going to have fun re-drill every 5 years my portal to try to find a reliable system.
