Is there a way to trigger an automation on the esp8266 use a card number? I would like a fail back way to trigger onboard autionation if wifi goes out. #2

Yup, you can just add code to the on_value to run a lambda to compare the card number and trigger the door.

Would it be possible to provide an example?

Sorry, ESPHome isn't really something i'm an expert in -- I would ask over there!

avwuff, I am hoping that you can help me out here as I have hit a wall. I am unable to get the keypad to group kep press together. I need to be able to press four keys and then enter to have it push out a code. currently it reports every key press as a single key press. It appears that you might have been trying to do this with we have a key code?

    void update() override {
        // See if we have a valid code
        noInterrupts();
        bool rc = DoWiegandConversion();
        interrupts();

        if(rc) {
            lastCode = millis();
        } else {
            if(keyCodes.length() > 0) {
                // We have a keyCode, see if the interdigit timer

expired if(millis() - lastCode > 2000) { // The interdigit timer expired, send the code and reset for the next string json_message(keyCodes); keyCodes = ""; } } } }

Actually, I didn't write my code to support keypads at all -- I'm kinda surprised you are even getting anything.
This was written for RFID keycards to be scanned!

I assume you are not interested at all in getting the keypad to work?

I don't have one to test with and don't need it in my use case... keep in mind, all I did here was take someone else's Wiegand reader module code and marry it so it would work with ESPHome.
