While it isn't easy to combine on/off into a single flow, there's a way to do it making use of an ONLY IF, as indicated in my "cat heaters on/off" flow.
When I'm at home, the temperature is 70°F, so I don't need the cat heated beds to come on.
When I'm not at home, I need them to turn on when it drops below 69°F in my bedroom, and turn off when it rises to be above 69°F in my bedroom.
The flow has two WHENs (over/under 69°F), and two targets (cat heaters on/off). The ONLY IF is that the flow runs when I'm away from home.
