Reporting back on my succesfull Tuya covert of the Hama switch. 
The converting process was rather straightforward with the instructions from their Github page and my rpi 3 B+ and for reference this youtube video https://www.youtube.com/watch?v=dt5-iZc4_qU.
Finding the right configuration took a bit of trial and error, but it’s now fully functional but this video helped to get a hang of the basics https://www.youtube.com/watch?v=eDoIkd58HRM. I’ve added the configuration to the Tasmota repository, up for review at the moment.
Thanks again for pointing me in the right direction and good luck for those who are facing a similar situation.
