The firmware file is embedded in the exe file as a binary.. I have extracted many of these using a hex editor and then running it through a bin2hex converter .
I got the same thing. Worked great for the zooz, but got the sleepy device msg on the Red Inovelli LZW30. Tried to 'wake' the switch up but couldnt get it to update.
At which point in the update did you get this message? Because if I understood the previous poster, it did update but he had to restart the switch when it got to that point.. Pull the air-gap switch and push it back in
Ooh I wonder if I could flash an Oomi Power Outlet with Aeotec Firmware ??
That'd help sort out my OCD as they appear to be just rebadged, reskinned Aeotec Smart Switch 6's but at 1/2 the price.
EDIT:
Saw this on the Aeotec Supprt page so I have NOT tried updating. Warning - Do not update Oomi Plug FT096 with Aeotec Smart Switch 6 firmware, this will cause your Oomi Plug to lose energy report calibration.
It's possible.. All it can do is tell you no.. If the firmware descriptor doesn't match the firmware on the device it will refuse to update.. So it's safe to try..
