IO with tahoma is better as it gives feedback on the status of the somfy devices and not that much negative reports. but expensive.
I have fibaro rollershutter 2 with somfy sonesse 40 WT (no RTS, just wires, 230v lift & tilt) should work ok, haven’t tested it yet as i get the horizontal blinds end of the month. but others using Vera and domotics tell me it works great.
Just try to avoid RTS as it doesn’t give feedback to homey, remote, etc and it doesn’t work great if the distance to homey is too far. also there a lot of posts on forums speaking negative on it.
forest works much better but expensive and xiaomi is cheap, availble on banggood now and seems to work fine.
i bought mine on http://www.onlinerolgordijnen.nl they sell blinds with motor allready built-in. avoid the non-somfy motor’s though they are crap. they are a lot cheaper then elsewhere. got 3 wooden blinds incl sonesse motor for 1800 euro where i got the exact same one 2 blinds without motor for 2100 euro at other store closeby.
