Domoticz

Trying my first test with blockly, but It looks that my events arent triggered @ all.
Even a test like this one doesn't work: https://www.youtube.com/watch?v=tgaNp1G4UcE

I can only find in "settings - other" that I can disable the EventSystem, but checked or unchecked it doesn't work either.
Also rebooted Domoticz, not helping,

Does anyone have a clue what I'm overseeing?

I'm running Domoticz V3.4834 on a Synology DS214+

Isn't that working as expected?

I found my issue, you can choose between 2 different "If-Do" blocks.
If you choose the one where you can choose the "Else If" option, you MUST select it, you cannot work without it,
So If you don't need the "else if" option you need to use the other "If-Do" block.
