Hello,
I have 7 roller shutters that I want to control with Zigbee or Matter controllers. I am looking for something that I can put under the existing Gira 55 wall switch buttons, inside the wall. It has to work with the buttons on the wall for manual control. Preferably the buttons should also be detected by the controller and available over Zigbee (or Matter). The reason for this is that I want to detect that a button was held for > 1 second, which should initiate the roller shutter to move all the way up or down by itself. Normal operation would be dusk/dawn based control. Does such a module exist, and for a reasonable price?
I had some pretty small and nice Zigbee modules that I ended returning because I wasn’t able to calibrate the up and down position and it was only a pass-through for the wall switch buttons.
