@Automated_House , I got an absolute ear-full by speaking w Somfy tech support today. I had it all wrong… MyLink and TaHoma are the same thing- Like a Gen 1 (MyLink) and a Gen 2 (TaHoma). MyLink is being phased out completely.
MyLink: 16 channels, capable of 16 scenes.
TaHoma: 40 channels capable of 40 scenes.
You were correct- TaHoma is the one that ST works natively with, no Groovy involved.TaHoma is Zigbee
ZRTSI: Converts RTS to ZWave. Theoretically it works w ST as a ZWave device, but like a light switch… either on or off (meaning the shades would be either fully opened or fully closed- nothing in between).
Somfy Clever is an RTS motor with its own ZWave embedded. You can integrate as RTS (via TaHoma), or directly via ZWave- however it might need a custom handler. Since TaHoma is supported by ST, that would be the choice way to go.
Before today, I was sure that I would be purchasing ZRTSI, but it turns out that would have been a mistake.
