We have decided to kit a large number of ultra-small servers ** OpenBlocks ** for IoT gateways. The OpenBlocks IoT family has Web UI, a dedicated GUI application provided by Plat'Home, installed. According to FAQ of Platt Home, items that can be set from the Web UI such as network settings can be set from the Web UI. It is supposed to be set, and it seems that it should not be set with CUI (Linux command). If you include the scp transfer and execution of the application program, it will take 15 minutes per device. I decided to write a kitting script in Python because it is possible to reduce the total man-hours by creating an automation program from the beginning rather than repeating troublesome GUI operations dozens of times. It sounds good to say that it reduces man-hours, but in reality, I really didn't want to do simple work.

Automating web UI operations

Automated browser operations with Selenium. It's a simple web application, so you're not doing anything special just by making a GET request, typing in a text box, or clicking the save button.

Automate file transfer and ssh command execution

Using paramiko and scp packages, we automated the transfer and execution of the application deployment shell. If you try to do it manually, setting the key is a hassle.
