I'm sure it is, but not having done much playing around with web hosting sites in the past I had me scratching my head for a couple of hours. Hopefully adding the info will save others the hassle.
As I said before, I have my devices set to check for new firmware in the early hours, and they send me a Pushover message when they restart, The message contains the MAC address of the device and the Firmware compile date/time. The next morning I see the Pushover message and know that the update was successful, then I manually go and delete the code from the webserver. Not very elegant, but it works fine for the occasional tweaks to code that I have to do,
