I’m not behind a computer right now so just re for - “send a channel refresh command” - please use something like
myItem.sendCommand(REFRESH)
my bet is that if you send above command to i.e. LP_hal it should trigger a status refresh …
There are many samples on how to use the REFRESH command, i.e. SystemInfo - Refresh Items Manually … Please let me know how it goes if you decide to give it a spin - so trigger a REFRESH when i.e. Button_on gets turned ON via Paper UI (or whatever UI you use) …
