In blockly it is easy to do somthing when a switch is on, or off, but what if I want somthing to happen if the switch is changed from eg off to on.

why? because if i eg want to receiv a E-Mail when a switch is turned on i will be spammed with emails if i use "if on"

Have you tested how it really works?

You can check the lastupdated time, you can create an additional virtual switch to check the status change.

In my scripting I 'memorize' when the last message is sent. I then only sent a new one if a certain time has passed. Like when someone presses the doorbell 3 times I only get 1 notification.
I would also suggest looking for another notification system than email. I believe Telegram or Pushover is way more suitable for this.

this is a good solution in your example with doorbell, but not if i want a notification when a light is tuned on (and it stays on for many hours, for example)

But yes, I will try Telegram or Pushover

I wrote 'In my scripting'
I don't use blockly, only php.
In php could be as simple as:
if($switch=='On'&&$switchtime>time()-60) telegram('switch X On');

lastupdate is in the forum or in the wiki somehwere.

Create a virtual switch
set it to on when e-mail sent and check if it is on and do not sent in that case
set the virtual switch to off when the concerning switch is set to off

Ok. So I don't understand the question. I have belived that all the switch action is event based and event occures only when switch is status changes so notification is send according change not state.
My bad.

I use lua, not blockly.
When an event is fired, all device lua scripts are run. It is up to the script to react or not.

Yes. But if in the beginning of your Lua script you check 'if devicechanged...' and so on it does trigger only with edge not from state? I understand that OP get spam emails from solid state and that's what confuses.

Devicechanged is only for the device that triggered the event scripts
