Welcome,
I am planning to upgrade my existing external roller shutter installation, which is controlled by Nice Mindy TT1N and add a Shelly 2.5 (*), allowing me to control the external blinds additionally via HomeAssistant.
What I want to achieve is to be able to control the roller shutters with both the remote control Nice Ergo 6 and the (new) Home Assistant automation.
I would like to make sure that the wiring diagram of my planned installation shown below has no major flaws and is safe for the existing installation.
.
The reason for keeping the existing Nice TT1N wireless module is to allow children and visitors to control the existing roller shutters (as they will not have an easy way to access the HomeAssistant).
(*) - Shelly 2.5 is the module I am familiar with, but I am open to other suggestions that can work seamlessly with HomeAssistant and do not need a connection to the public cloud (they are only controlled locally).
