I’m about to do a mashup of the office coffee maker and an arduino. I want to get the coffee maker to tell me when it’s on/off, how long it has been on, how much coffee is in the pot and how hot it is.
All that should be fairly easy to solve but my problem is rather the communication. From my room to the kitchen it’s roughly 15 metres but the only open space is a narrow hallway. In other words alot of walls to penetrate. Most our wifi users have a problem with these walls.
What would be the ideal way to communicate with the arduino in this environment?
REGARDING WIFI ISSUE:
Regarding WIFI, since I do have a valid reason to do something about this, please dont refrain from suggesting it if you think it would be the best solution.
