@scubamikejax904 sorry for the delayed response.. ive had this response saved as a draft for over a month..
This was pretty much where i hit a wall when i was actively developing this project. At the time (on version 2.2.x) there was limited ability to hook into the hsm intrusion and create a delay style entry.
if i were to try again i would likely use something like nyckelharpa: [Release] Nyckelharpa, an HSM Extension
where you can better control hsm arming/etc and have a custom entry delay. There would still need to be some work for it to display properly on the keypad,
unfortunately, using the keypad input display is limited currently, as there are inherent issues if other apps are attempting to display content on the input display, and you hit a key on the keypad, the keypad will take priority and wipe out the previous message, or in the case of a countdown, they might fight over the text input and it will flash between the 2 messages. There is definitely room for improvement of the keypad input display, that may include a 2nd line of text that can persist for a period of time or something. Definitely a lot of room for improvement.. unfortunately, I just dont have the free time to continue developing right now. I am happy to review pull requests, and can add other contributors to the github repo if someone wants to take on continued development of the project.
