I would like to use a NodeMCU with esp8266 flashed with Tasmota to bridge a Velux KUX 100 remote control the up and down buttons for my shutters. The NodeMCU has several GPIOs. Is a direct control possible or in addition a relay is needed. I still have an Elegoo 4 channel DC 5V relay module with optocoupler at home which would work, but that's way too big for me. Is there mini ralais if needed. I mean something: https://www.pollin.de/p/miniatur-signal ... ler-340615. For every tip or suggestion I would be grateful.
many Greetings
