I have working TCP communication with heating main unit.
This flow will send a TCP commands (sep by step) to main unit to make a temperature change :

Problem is, that I want implement confirmation, that I want send this commant to prevent unwanted click on the smartphone and also implement status that operation is running - like LED when semaphore is running. After each command I'm also receiving answer from main unit 0xFF that command was successfull, but I don't know how to implement into flow.
Thank you for help
