In the IR menu -> klick "MANAGE" -> click one of the kebab menus (...) and then "Play".
The command works every time.
But when the command is connected to a button and the button is pressed it only works every 1 of 3 or 1/6 times.
The connection between the hub and button if ok, because i can se the Led blinking on the hub every single time.
And the IR receiver is fine and can receive commands very fast from different remotes.
i have tested this on all my 6 Hubs, with 6* 4 buttons, all have the same problem.
It seems to be a software error since it works perfectly with the "Play" test action .
