Lost in mqtt channel add

Close but…Spent lots of time on this, not sure I really need the transformation as the tasmota only has command on and off.

Summary: See item, see commands in log, broker at *.228 sees message from OH and from mqtt util. Only util makes it to switch.
Mystery but guessing OH broker sees (Green Line) message but not formatted correctly so no change made to switch. (could be knowledge of message formats)
Orange line points to result from util, light changes and status. Not using user client info could be issue?
Feels like I’m trying to put pegs in holes with blindfold on? Help point me in right direction? Must be messing up channel somehow?
sorry about small pic
