Most keypads can only be programmed with one “release” pincode as far as I know.
I found a Popp outdoor keypad at Robbshop, but it’s not available anymore…
The Popp Keypad is indeed the device is was looking for.
Did found one at POPP Keypad Z-Wave Plus kopen? | Momotica but apparently I bought the last one because now they are out of stock.
Yes, for the purpose discussed here even without Heimdall. Any code entered on a Ring Keypad will be available as a tag on a trigger card. Mind you, this device is to be used indoors.
