Is there a way to control this device directly from smartphone?
I want to make a portable device used in nature, and I'm wondering how can I access the device features without a router connection...
I mostly need to set timers, turn it on/off...etc
You can share internet from your phone, for doing this you will need a 2nd phone only during the pairing of the device to configure wifi parameters. Then if you plan to use the device, where you are and within wifi reach of your phone you should be ok.
