I try to build an events that will send a single messages when temperature drop below 90 degree C. In this examples its start to send message when temperature is under 90 but it’s continue to send until I deactivate the events 

How to make this event to send just one message when temperature passes 90 and below and then only send message next time the temperature drops???

I'd suggest adding a user variable for which you give some desired value (true/false, 0/1, on/off...) when temp passes the notification threshold to either direction. Then for the notification, add additional check for the user variable to send it only when the variable still says temp > 90 but actual temp is < 90. At the same time the user variable updates and with the next check it will not send a message anymore.

Also, add a condition to update the user variable only in case the value needs to change (otherwise it will keep updating the same value).

This might actually be a bit easier to be done with LUA but should be working in Blockly too...

ahhh ok so if i have a variable send= 1 or 0

If temp is higher then 90 then send = 1

If temp is lower than 90 and send = 1 then send message and then set send = 0

Nice thanks

Yes, something along those lines was exactly what I meant

And possibly also consider: ...and vice versa - if you want to avoid updating the variable when the target value is the same as the current value.

Thanks This works

Nice!
