@zebmina I am about to purchase ~30 433mhz controlled blinds that are normally controlled with a 15 channel remote - I think these are made by several Chinese manufacturers but all use Dooya style remote control. The manual says you must pair each blind to its own channel, and then there is an "all" control. How do you have 10 "zones"? Do 10 remotes each output a different signal, so you can have 10 "all" groups? Or can you pair multiple motors to one channel using one remote?
