I'm assuming this is out of your hands but thought I'd report it anyway. I've just reviewed the Itead Sonoff B05 RGB lamp and their L1 Lite RGB Strip controller both of which work on the EWELINK APP.
I did note that the EWELINK API does not seem to support RGB control yet (unless I missed something) so I'm asuming thats why your NODES also don't seem to support RGB lights. I'm hoping all of that is on the way. The nodes you have worked fine on the latest Node-Red and it took me only a minute to get running what is supported :-)
