Chinese New Year is coming up (February 8?) and most vendors take 1-2 week vacations around this time and shipments can be delayed. Keep this in mind if you wish to order from Ali or eBay, do it soon or your order may wait until after the holiday.

For the internet you could add a GSM shield to the gateway or a 3G usb stick to the Rpi. If you only pay for the data that's send than you could leave the internet on 24/7. I would put the Rpi running the controller in the same house as the gateway so no data is lost because of a loss of the internet connection. If you would want to connect to the controller to check the statistics or status of the switches and sensors you would connect to the controller via the internet. Using a dynamic dns service it wouldn't be a problem if the ip-address of the controller changes. Sensors are connected to the arduino via cable. The sensor arduino connects to the gateway wirelessly. Thinking of it you could connect the Rpi to a VPN server running in your home so it will get a local ip-address of your home network. That way there's no need for the dynamic dns service.
