I work for local.ch, the swiss phone book, and one of the challenges we face is keeping the information about opening hours up-to-date and correct. Correct is particularly tricky to get right for SMEs and Mom&Pop's kind of stores because there are always exceptions to the general opening hours (most common case being close for holidays).
So, we thought it would be cool to use LoRaWAN to experiment with an automated approach to opening hours collection. The idea would be to retrofit old-school "We're open NOW" signs with a tilt sensor and an Arduino+LoRaWAN to collect info every time the owner opens/closes the shop.
With that info, we can extrapolate general opening hours + get all the exceptions = perfect information.
We've started now working on prototypes of the idea, if it goes well, it'll be tested on the TTN in Zurich.
