I searched on ebay and found most if not all of these keypads do not have any labels on C and R on the pins. Do they have a “standard” pin assignment? If so, what would that be?

Hi! I’m using this keypad https://learn.adafruit.com/assets/89978 and have wired via your instructions above, except for the C4 connection (mine doesn’t have a 4th column).
I’m able to get it to connect to homekit, and am able to access the panel, but only the number 3 is working, which makes me think I’m wiring things incorrectly somehow. Any recommendations? Does this support 3×4 matrix?

Hi, I really like this! Can one use multiple Keypad devices in one HomeKit system? I just flashed a second ESP and it works ok in WiFi, I just cannot pair it to the HomeKit system.

Using the same HomeKit code (11111111), it allows me to register the 2nd device if I disable the 1st but afterwards both don’t work…
If I don’t disable the 1st I cannot register the 2nd because it says its already registered… somehow the 2 devices are not seen as different ones by HomeKit.
If I unplug one the other works.

I got it installed. I can add 2 devices to HomeKit and assign Automations, but they don’t get executed even though I can see the sensors trigger…

Yes, it triggers the event correctly but the automation doesn’t start, strange…
