yeah, I had the same thought. but then I didn’t any way to actually order from them so it seems kind of a waste of their time too.

I find it interesting that, if you look at their website, their wireless modules look incredibly similar to those made by Haccom. Specifically, what caught my eye was the connectors used. Those connectors on the Haccoms are terrible - so I find it interesting that two Asian companies produce similarly featured modules with identical terrible connectors.

Do they work in irrigation system? Can I buy it in Hong Kong?
