Controller operation outside the country?

Hi,
My Name is Mohamed, from NJ. Irrigation controllers contractor and I have clients in US, Dubai and Africa. I am so glad to be part of this wonderful forum.

My wish is:
I know from support that Rachio is not supported outside the US and definitely all functions that depend on connecting to server by way of Wi-Fi will not work abroad.
My wish and suggestion is, to add another option in addition the Wi-Fi connectivity, to program, reprogram and update schedules by Bluetooth, the App will be able to switch from Wi-Fi to Bluetooth by clicking on one of two option buttons . :pray:
