Hi liudr. Thank you for the revised code. This does work but when the alarm is tripped any keypad press turns the alarm off. I tried it this morning. I am reading all I can find about state machines too.
Perhaps I should leave it today as I have had more injections into my spine and they hurt badly. I may have a look later if I feel better. I hope I am not taking up too much of your time on this.
Regards
Jeremy
Good! Yes, that feature can be turned on and off inside the alarm case. I don't kow what you exactly wanted.
