That doesn't really make a ton of sense. Stores have personnel in them pretty much all the time, who can take action when necessary. Data collection for monitoring, forecasting, etc. is a reasonable thing to do obviously, and centralized aggregation clearly makes sense. But remote control smells more like a fanciful shiny tech bauble than an actually useful, let alone necessary, feature. It's easy to imagine how that feature got sold internally within an engineering organization, but it's very hard to imagine customers clamoring for it.
