A wireless access point is required for connecting wireless devices to a network. Most home networks rely on one wireless router combination device to fill this role. A home automation controller enables low-power wireless communications with simple, non-data-intensive devices such as light bulbs and locks.
I fly passenger Airbus A330s and A340s. I've never flown a cargo only aircraft so I can only answer about the passenger Airbus. We can set the temperature in the back cargo compartment (the hold or the bulk we call it) between 5 degrees Celsius and 25 degrees Celsius. The normal position for the selector is around 15 degrees Celsius.
Pets traveling as cargo. Whether your pet is flying as checked baggage or cargo, it will travel in a temperature controlled and pressurized compartment right under the cabin. Most airlines flying larger aircraft (not commuter planes) accept live animals as cargo and have made special provisions for their handling. Exceptions to this are Southwest, AirTran, JetBlue, Frontier, Virgin America, and those airlines that do not accept pets in the cargo hold.
