I guess I am taking a little more cautious/skeptical stance when it comes to the auto-replenishment feature touted by many IoT pundits and vendors. If you aren’t familiar, this would allow a device to determine that you were out of or running low on a given consumable (be it a food item, dish soap or toilet paper) and then order more of it on your behalf.
Here is the problem: the vendor and the device don’t have your best interests at heart and might tend to exaggerate the current state of consumable and (maybe) tend to order more of it more frequently that you might actually need (or want). For example, if you have ever owned an inkjet or laser printer you have probably experienced this already – persistent warnings/notifications to replace a toner or ink cartridge when, in reality, the useful life of the item is much, much longer that you are being led to believe. Heck, I have a laser printer that has been telling be for 13 months that I need to replace the toner. In that time my family and I have printed hundreds of additional pages with this ’empty’ toner cartridge.
Consider also the existing confusion over the meaning of ‘sell by’ and ‘best by’ designations on other consumables (most notably food). What if vendors add a ‘replenish by’ or ‘order by’ date into the mix? Not a great situation for consumers, especially if they have delegated this to an networked device in the name of ‘convenience’.
