Smart JUNG Wall Switch AS is designed to make your blinds smart without having to replace the old buttons from the JUNG AS series. The blinds are controlled in the control box via SOnOff 4CH Pro with Tasmota flashed.
Initially, the idea was to use the original button and switch to 230V wiring via 5V or 12V. However, after a lengthy internet research, this was advised against. To solve this problem, a 433Mhz wireless switch from SOnOff was purchased and the microswitches were connected to the wireless switches.Soon we plan to take a SOnOff Mini and connect a PCF8574 IO I2C expansion module to it. This will avoid the use of batteries because it can be connected directly to 230 volts. It is also smaller and more compact.
