I’ve hacked-around your earlier code to add-in the necessary serial print statements.
In the process I’ve seen some things that are problematic and tried to fix them. I can’t do a test compilation, as I don’t have the necessary libraries installed, so there may be the odd compilation issue that needs to be fixed…

There is an issue with the logic around the timer intervals, as once the setInterval timer is initialised it won’t be updated when your airflowduration and airflowdelay values are changed in the app, the device will need to be rebooted to re-initialise the timer with the new values.
Once the code structure and functionality is resolved then we can look at a solution for that.
When this compiles and is uploaded, if it doesn’t work as expected then post the full serial output from boot-up, with timestamp turned on.
Once again, please do not paste snippets of code and snippets of serial output, they mean nothing. If you amend the code then post the full code and the full serial output.
Pete.
