Can anyone suggest a basic rain sensor autocloser that I could retrofit to an existing top-hung Velux window? The only ones I can see on the Velux website are for centre-hung windows.
Ideally, the window would be opened manually, and close automatically if and when it rains - so no need to fanny about with remote controls. Is there a cheapo/DIY solution which simply winds in a chain attached to the window frame when activated by a rain sensor?
The Window is a GHL M08. Approx. size 700x1300mm (w x h). Maximum opening from sill to bottom of open window is approx 650mm. The wider I can open it and have it reclose, the better. It's for a loft bedroom that overheats in summer.
Mains connection, transformer, battery or solar would all be fine, in terms of power supply.
I'm confident DIYer and can handle mechanical/electronics projects, so it doesn't need to be a single off the shelf product.
Thanks!
