Finally managed to flash this Mirabella Genio GU10. I started off using v2 of Tuya-Convert. I spend ages resolving all the errors on the PI but could not get it to flash. I started 3 times with fresh Stretch versions but had no luck. I also tried the old version but still no luck. I had given up as I spend countless hours without success. I decided to give it a last go. I had a fresh Stretch that only had version 2 of Tuya-Convert installed. I created a new directory. Downloaded the original Tuya-Convert. I ran the āinstall_prereq.shā and put my GU10 in programming mode. After a few seconds it stopped blinking so my first reaction was, here we go again, but after 15 seconds it went off and started flashing. Now I have 3 GU10ās on Tasmota. I struggled to find a template on blakadder but found this one to work.
