Press button to send msg.payload

[diegotorpocop]

Hello,

The dashboard I am creating will be used in a touchscreen, therefore I am placing buttons (numbers from 0-9) that will emulate a keypad. When I press a button it will send the number 1 to a text input.

The problem I am facing is that it only sends one message of value 1 or if I press the button 2 it erases the value of 1 and it only lets one value of 2. I want to be able to for example type an ID but the button will only send one message payload (something like concatenation of strings or summing numbers that will be later stored as a string).

You would need to store the previous numbers and add the new number to the end of the stored value each time. example below
