It’s entirely possible to run browser tests solely on a Raspberry Pi with Firefox, Selenium and PyTest. With Virtualdisplay, not even a display for the Raspberry Pi is required (headless).

Home automation with rpi-rf_send and rpi-rf_receive for 433MHz rc switches

So far, i’ve used the Python module pi-switch for controlling rc switches, but it is no longer maintained. rpi-rf is a very viable alternative. In this tutorial, you’ll use a 433MHz receiver with rpi-rf_receive for decoding the switching code for a common rc switch, then trigger that switch with a 433MHz sender and rpi-rf_send.
