Pin Roles

You can set pin roles in "Configure Module" section or use one of predefined templates from "Quick config" subpage. For each pin, you also set coresponding channel value. This is needed for modules with multiple relays. If you have 3 relays and 3 buttons, you need to use channel values like 1, 2, and 3. Just enter '1' in the text field, etc. Currently available pin roles:

• Button
• Button_n (as Button but pin logical value is inversed)
• Relay
• Relay_n (as Relay but pin logical value is inversed)
• LED
• LED_n (as Led but pin logical value is inversed)
• Button Toggle All - this button toggles all channels at once
• Button Toggle All_n (as above but pin logical value is inversed)
• PWM - pulse width modulation output for LED dimmers (with MQTT dimming support from Home Assistant)
• WiFi LED - special LED to indicate WLan connection state. LED states are following: LED on = client mode successfully connected to your Router. Half a second blink - connecting to your router, please wait (or connection problem). Fast blink (200ms) - open access point mode. In safe mode (after failed boots), LED might not work.
• DigitalInput - this is a simple digital input pin, it sets the linked channel to current logical value on it, just like digitalRead( ) from Arduino. This input has a internal pull up resistor.
• DigitalInput_n (as above but inversed)
• ToggleChannelOnToggle - this pin will toggle target channel when a value on this pin changes (with debouncing). you can connect simple two position switch here and swapping the switch will toggle target channel relay on or off
• DigitalInput_NoPullUp - same as DigitalInput but with no programmable pull up resistor. This is used for, for example, XR809 water sensor and door sensor.
• DigitalInput_NoPullUp_n (as above but inversed)
• ADC (Analog to Digital converter) - converts voltage to channel value which is later published by MQTT and also can be used to trigger scriptable events
