Hi everyone,
I have successfully paired my Somfy blinds with RFLINK and HA 
What’s working
Every cover is working fine individually, and I can send UP/DOWN/STOP commands with almost no delay and every blind is within reception range.
I’ve added the physical remote aliases too, so when someone is using one of these physical remotes, HA is aware that the blinds state might have change. So far so good !
What’s NOT working
I’ve created a cover group including all my eleven blinds. When I try to CLOSE/OPEN the blinds using this group, I have a very erratic behaviour : only 1 or 3 blinds will randomly answer the command. Sometimes one upstairs, sometimes 2 downstairs…
It seems that HA is sending all the commands at the exact same time :

My guess is that this must create a transmission jamming (too many commands on the same frequency at the same time) but maybe I’m wrong.
My questions are :
- Do you guys have this problem ?
- Is it possible to tell HA to add a delay between each command (let’s say 1 second) ?
Feel free to ask me if you need more information.
