Comparing two temperatures & controlling one plug

Hi!
I have a fan with a plug that I want on if “Bedroom C°” < “Office C°“ else off. I think I have managed to create the flow as it works when tested, but not alone.

What am I doing wrong?

This will trigger once and that is not what you are aiming for.

Replace the WHEN card with “Temperature has changed”.
In the AND section place a logic card where you compare both temperatures.

Here an example with LUX:

The flow should work this way, but not with the “else” option.
So you need an additional flow to turn the fan off again:

When…
– Temperature (Bedroom) becomes less than temperature (Office)
Then…
– Turn off

This makes perfect sense. I’ll try!

Hi!
When I try to create the temperature comparison (on my Aqara sensors) in the “And” section I can’t access temperature at all - only “Battery alarm”. Also if I do the comparison in “when” I can’t add the “temperature changed” in “And”.

Help!

Use a Logic card, as seen in my flow example.!

Don’t feel silly. We all started with nothing.

Almost every one misses this one the first time, so basically it is nog a particularly good user experience design.
