Abstract: The present disclosure relates to an environment control device (ECD) and a method using a wireless communication infrastructure for exchanging environmental data. The wireless communication infrastructure comprises a first Wi-Fi hotspot, and at least one of a second Wi-Fi hotspot and a mesh network. The ECD comprises a communication module for exchanging environmental data with at least another device over the wireless communication infrastructure. The communication module is capable of establishing the first Wi-Fi hotspot, associating with the second Wi-Fi hotspot, and communicating over the mesh network. The ECD further comprises a processing module capable of processing environmental data received from the other device via the wireless communication infrastructure, and/or transmitting generated environmental data to the other device via the wireless communication infrastructure. The ECD may consist of an environment controller, a sensor, a controlled appliance, and a relay for wired devices.
