I've several roller shutters, and my plan is to enhance all with a dedicated Shelly 2.5, but after the first installation, the physical switches just don't work anymore.
So I stopped until I found a solution...
The switches are from the Italian brand BTicino, model L4037 (interlocked switch), and, before the Shelly installation, work just fine.
Someone can explain to me if and what can I do?
Thanks in advance
Enrico
