Looking for something like a scene controller, however one that is a keypad and can be used to do different things based off a code. (preferably battery controlled)
For example, if I put a smart lock on a door (one that doesn’t have a keypad or anything), and put the keypad next to it, if I set 0000 as a pin on the keypad, can I have the keypad to get home assistant to unlock said door?
As well as do stuff like turn lights in said room on, etc.
Was looking around but haven’t seen anything like this so far. Thanks!
Sounds like a cool idea, but think there might be a few caveats you will need to work out.
A keypad that requires more than one button press to trigger something - in your case 0000 to open the door, will require a controller to parse the input. Something like a raspberry pi or ESP board.
This would almost certainly rule out battery powered.
Then you will have to work out if you want the controller to the check the inputs to a known list of pins and produce the output you want, or try to do it in home assistant. Each way is possible (I think) but will certainly take some time to build.
If you are looking to create a smart access system, RFID/NFC might be a better option? Plenty of systems out there.
I have a ESP8266 connected to a keypad in my workshop that controls a few items, but is powered by power supply and each button is assigned to its own function.
