Well with a LOT of help on the templating from @tom_l I was able to modify this script to be a little more user friendly on the front end, as well as include a user name that I can use for presence announcements when some arrives. I thought I would share it, so hopefully someone can take it and make it even better. The original premise is still in place. I created the following helpers for each lock:
->input_select.code_slot (as per the original script w/ 6 code slots for my needs)
->input_text.code_slot_front_user_0x (6 individual Code Slots for each lock to store the individual user names)
->input_number.front_lock_code_0x(6 individual Code Slots for each lock to store the individual user codes)
I ended up putting the following in a package because the script editor kept destroying the code when I put it into the scripts.yaml
script:
set_lock_frontdoor_code:
alias: Set Front Door Lock Code

- service: zwave_js.set_lock_usercode

Obviously you would need to create a card and code for each individual lock you want to control, but for me it’s still way less bulky than Keymaster (which I think is a brilliant integration! Just more than I need). This has been tested and confirmed working on my three Yale YRD256 locks. Hopefully it works for you. Good luck!
Thanks to @dposluns for sharing the original code and inspiration behind my hack!
