The present disclosure relates to an environment control device (ECD) and a method. The ECD and method comprise a first communication interface, a second communication interface of the Wi-Fi type, and a processing unit. The processing unit sends a DHCP-DISCOVER message via the first communication interface. The processing unit also configures the ECD to operate the second communication interface as a Wi-Fi Access Point if a DHCP-OFFER message is received in response to the DHCP-DISCOVER message via the first communication interface. The processing unit also configures the ECD to operate the second communication interface as a Wi-Fi hotspot if no DHCP-OFFER message is received in response to the DHCP-DISCOVER message via the first communication interface.
