Controlling a room heater with a Fibaro FGBS-001 and a DS18B20

Hi, I am trying to create a scene to keep the temperature of a room between two values.
I have an electric heater controlled by a Z-Wave plug and a Fibaro FGBS-001 with a DS18B20 temperature sensor.
My first attempt used two scenes, one to switch on the heater when the sensor’s temp fell below 18 degrees, the other switching it off when the sensor reported above 20 degrees.
I found that the heater was correctly switched on by scene one, but the second scene did nothing.
I then played around with PLEG for a couple of fruitless hours.
Can someone point me in the right direction?

Cheers, Gordon

Umm, welcome.

I sound like a stuck record. Reactor can probably do that much more simply.

Thanks! I was hoping for confirmation (or otherwise) that what I wanted is not possible using standard Vera scenes. I dont understand why Vera can switch when the temperature goes low, but not when it goes high.

Use reaktor plug in and use the between condition…too easy
