This is awesome! I've been wanting to build something similar to this for many years. I also wanted to hack together a prototype with a Raspberry Pi and scale, and automatically add items to a grocery list whenever the weight dropped below a certain threshold. Automatic ordering and delivery would be great too, but I don't think that would be viable in most countries. I'd love to have a smart fridge / pantry where every spot on the shelf had a scale, and could detect when things are running low. Unfortunately most of the big appliance companies seem to be spinning their wheels on strange and useless "innovations" like putting Twitter on your fridge. I think starting with a single product and having a subscription model is a really smart idea. Unfortunately Amazon has an enormous edge, especially after acquiring Whole Foods. Also the Amazon Dash button, and Amazon Go for automatic checkout. I've been expecting Amazon to put out a product like this for a long time (maybe their own smart fridge with automatic restocking.) So I think it's very brave to go into this market! I hope it works out well with the coffee, and that you're able to expand into other products.
