Shamless project plug - Introducing Roll Pole. A Photon based toilet role pole which, when you run low, tells IFTTT to put toilet paper into your Tesco.com shopping basket.
Perhaps more interesting than automated ordering is the use of the Photon in low power mode and trying and get a single set of batteries to last a year, or at-least longer than a pack of toilet rolls! Ask me in 12 months how it has gone.
Side note: Yes I could use an Amazon Dash button, ironically having just written the project up on Hackster yesterday Amazon launched the Dash buttons in the UK today. However, the Roll Pole is way more fun and doesn’t need somebody to press a button
Actually, don’t ask me how the batteries have done, you can see how they are doing for yourself: https://ddd.tinamous.com/Devices/LooRoll2/VBatt
