Never able to connect and threw it away
I just threw away a 200.00 device I was never able to use. My advice is save the frustration and anger and just throw the 200.00 in the trash now. I was very excited about airgradient. After countless hours of attempting to connect to the hotspot, having the device interfere with our wifi connection and to other devices I gave up and threw it away. You cannot connect the device to https period. Apple will not allow you to connect to anything g but an https. I attempted a connection on an android that was wiped clean and still could not connect the device to a hot spot. So, I just threw away a few hundred dollars. Very unhappy with this and do not recommend the device to a general user. I am tech savvy but not a programmer, so bye-bye Airgradient.
