Great, thank you for the hints!
I will update my solution, maybe can be helpful for the forum.
One more thing: Is possible to run some simple code (like a clock on the small screen) without an internet connection?
I'm new here, I started using Obniz only in the last few weeks and it's very funny.
I made my obniz to control the light and AC in the room, like the example, I would like to know if there's a way to have the code (like html page) always running on the board and then access to that page to control the house by pressing buttons or automatically (for example when the temperature goes down automatically start the AC).
