Hi.
This is a very old issue which now I have fount time to bring. When the HA companion is set to languages that are RTL (Right to Left), the numeric keypad in Alarmo is reversed. The 1 digit is in the right hand side and the 3 is in the left hand side. This is natural in text but it should be considered LTR at all times.
This is a custom integration so it’s best to escalate your issue/FR in the GitHub repo
