Experience ultimate convenience - shutters controlled via smart home and state synced

In our house we have pre-installed radio controlled shutters which listen to 433 MHz radio signals. I wanted to get them controlled in a smart way to make them wind up/down synchronized to the sunrise/sundown times and control them via smart speaker.
I took a deeper look into the radio control signals being sent out by the manufacturers original radio remote control with an oscilloscope and was able to recognize some patterns in the signals - there was one part of the signal identifying the addressed shutter and the other part of the signal defining the command up/down/stop. With this new information I was able to produce those control signals myself by attaching a 433 MHz sender to the Raspberry Pi and sending the control commands out via software, allowing me to control all of the shutters in my house with no limitations in number or timing concurrency. I now developed a timer that takes into account when the sun goes up / down every day and controls the shutters respectively - up in the morning, down at night. Additionally I was now able to connect my solution to the cloud and develop a smart home skill for #amazonalexa as well as a smart home action for #googleassistant. Super convenient to be able to control the shutters via app, via voice control, in automatic mode but also just still with the original radio remote controls shipped by the manufacturer (sometimes just handy to use those instead of an app / a smart speaker).
There was just one issue left - in order to maintain a proper state of each shutter in the cloud, it was necessary to be able to listen to the signals sent out by the original radio remote controls. Otherwise once one of those radio controls were used, state information of the shutters in the cloud was lost. Therefore I attached an RTL SDR device to the #raspberrypi which listens to 433 MHz band, receives those radio signals and transfers those to the cloud for updating the state there - voilà!
We are super happy with this solution that makes life much more easy and convenient. The whole solution is implemented in #python.
