• Make sure Air unit is updated to latest version (above 21).
  • Switch the mobile internet from wifi to 3g and check if delay exist. If it works fine then there is some issue with the wifi to which the mobile phone was connected.
  • When many devices are connected to the same wifi then considerable delays can occur while controlling. 
  • Wifi should have good signal strength at the Air units location.

  • If the wifi repeater has the same name as the main wifi then try changing the repeaters name.

  • Change the wifi settings in Air unit  temporarily to connect to a mobile phone's hotspot and check if the delay exist. 
  • Change the network settings in Air App to forced local so that local network is used whenever possible.
