Somfy Window Shades & SmartThings Integration Guide for the year 2020! (ZRTSI)

[mrmrmrmr (ilker Aktuna)]

@Hershey , thanks for the great instructions.
I was also using the sync app from:

[OBSOLETE] Blinds Sync

For folks who have Somfy blinds where you have multiple channels on your Somfy controller, this app will synchronize the status of your desired channel to the rest of the other channels on your Somfy controller. It does not actually send the zWave commends to the other channels, but rather just retrieves the master blind status and replicates it across the other channels to maintain an accurate state of all of your blinds. This is needed since the Somfy controller ZRTSI does not inform ST about it’s state and some people will have an all blinds channel which controls multiple blinds. It will only work with @E_Sch’s Somfy Device Handler which can be found at Device Handler Eventually, I will get this on GitHub and figure that out. Special thanks to @tgauchat who provided guidance here. …

this was working fine with the old ST app. But now with the new ST app, I can’T make any change to this smart app.
is there any experience on this ?
why can’T we modify the smart app settings ?

edit: solved
I had forgotten that I modified the DTH to remove window shade feature.
of course like that it doesn’t find the shades.

but why did I removed the window-shade capability ?
because it doesn’T work fine on Alexa
