All Grove sensors should come with the mounting rivets they were designed to be attached with, or you should sell packs of the rivets.
Mounting the grove sensors with the plastic push rivets is really the best way. You don't sell the rivets separately. Why not?
My original mounting kit had some, but I have used them all on projects, and I need more. I know you still make them because I see that they are used in your grove environment kit for Edison.
Please notify me how I can get some more rivets. Maybe I will have to buy them from your supplier directly.
