I have Digital Weather Station from Sencor with external remote sensor model - SWS THS

It was working very good for me all the time. Recently I bought some 433 RF receivers and was playing around,
when I decided to try to tap data from this external device and read it in Arduino/Wemos.
I started looking for different ways to achieve this goal, started reading different reverse engineering tutorials, like:
http://hackaday.com/2015/03/01/reverse-engineering-wireless-temperature-probes/
http://rayshobby.net/reverse-engineer-wireless-temperature-humidity-rain-sensors-part-1/
https://rayshobby.net/interface-with-remote-power-sockets-final-version/
But being lazy I searched the web for any existing codes. I came around this example: http://arduino.cz/meteostanice-ovladana-arduinem/
It is done by Czech enthusiast : Zbyšek Voda and he already decoded and provided main elements of the SWS THS protocol.
After some translating, cleaning and structuring , The result is obvious:
