Blockly 1=0 always true and other problems Topic is solved

[AlanGpio]

Hi I've spent most of the day experimenting with a Blockly script without success. It would be nice to get another opinion. This is the script:

The Else if 0=1 is for "parking" unused bits of script as I' was getting fed up with deleting and recreating bits of script.

The ShutdownButton (gpio6) is normally High and goes Low when pressed. It is defined as a Push Off Button in Domoticz and as Both rising and falling edge in sys/gpio. When the button is pressed for just a second this is the log:

10 seconds later the ShutdownStatusEnd Light/Switch comes on. Logic says that 1=0 should never be true.

Further the log entry "Else if if is triggered" should also never happen as both variables ShutdownStatusStart and ShutdownStatusEnd have been set to 1 and 0 respectively.

Note that my first version used dummy switches for ShutdownStatusStart and ShutdownStatusEnd and the behaviour was the same.

I'm running this on a Rasp Pi 4 under Buster and within a Docker container. Domoticz V4.10364 (c)2012-2019 GizMoCuz and Build Hash: 1cacdddf, Date: 2019-01-25 10:01:48

I'm tempted to do this in python script but I'm having problems accessing the gpio pins.

Thanks for reading.

Hi I've spent most of the day experimenting with a Blockly script without success. It would be nice to get another opinion. This is the script:

There are quite a number of posts on this forum mentioning that nested if's in Blockly does not work as expected. Just type

nested Blockly

in the search window on the forum and you will get dozens of hits.
Bottom line: "Don't use nested if in Blockly "
