Scenes if then else

to create a scene there is the condition “IF” and the action “THEN”
if i want to check the temperature i say “IF temp >= 19 THEN Relay 1 OFF”
I would like to do “ELSE Relay 1 ON”
how to do

Try IFTTT, eWeLink doesn’t support ‘else’ logic.

thank you
do you have an example

why in the conditions to test the temperature we can only enter an integer ex: 19 and not ex: 19.5
