Regex command

Hello, the other day I saw about such a wonderful program as commandFuison, it can replace the standard interface on any drawn you. And here I began to understand this program and then faced the question how to make status updated, that is, that when you turned on a light indicator in your program changed the colour. I saw on Domotiga and there to implement it only in Feedback Properites in Regex to specify this command “^id_value1(\d*)”, where id is the id of the device. But this method did not fit me as OpenHab no id, and maybe someone knows what is the command for Regex help.
