ESP32 keeps sending commands in loop (Balboa GL2000, no functional keypad)

[BenouGui]

Hello,

I am testing this project with my Balboa GL2000 spa controller.
I managed to connect successfully, but I noticed a problem: the ESP32 keeps sending commands in a loop.

• The result is that the jets are constantly turning on/off repeatedly.
• In the serial monitor I can clearly see that the same command is being sent continuously.
• My original keypad (ML400) is no longer functional, so the GL2000 is only controlled through this integration.

Questions:

• Could the absence of a working keypad cause this loop behavior?
• Is there a way to avoid re-sending the same command if the state hasn’t changed?

Thanks a lot for your work, and let me know if you need logs or additional debug info!
