If it's now 19° it can't do anything. It's not lower than 17 and not higher than 20, right?

ok heating scenario part 2....

anyone have any ideas how i would go about adding a scenario or perhaps another else if, so that if i turn my heating on remotely it will work..
as you can see ive got presence running with occupied so that when no one is home the heater turns off...
but i would like something so that if im half an hour from home and i know its cold i can turn it on before i get home

One way would be to add a virtual "Manual Override" or an "Auto" Switch

In your scenario you could add an "Override" switch that can work with the Occupied switch:-

If [Heating =On] And [Occupied = Off] And [Override = Off] Do Set [Heating = Off]

Then add the appropriate conditions to the first "Else If":-

Else If [Temp <= 17] And [Heating = Off] And [[Occupied = On] Or [Override = On]] Do Set [Heating = On]
(Note how the "Or" is "nested")

Below is a Blockley I use to successfully control a ceiling fan. Note where the "Auto" condition is required to be on to run the fan or turn it off. So I can switch this to regain manual control.
