I’ve already created a lot of advanced flows. Suddenly, all the advanced flows are grayed out and can no longer be started. Even when I create new advanced flows, they’re grayed out and can’t be started. A standard flow can be created and used.
I’ve read on forums that there might be an error in the flows or duplicates. I’ve tested it, and everything seems to be fine. For example:
The advanced flow in the example does not have a “Start” button anywhere. So the application does not know how to start the flow from the Homey app. So the flow is grayed out in the app. That is normal behaviour.
Thanks for the super quick respons.
Never had any problems without the start button but i’m going to try.
I’ve no idea where to put the start button but it seem to work. Any tips?
Thanks for the quick response.
Depends on what you like this advanced flow to do when you run it manually 
Ok, thank you for the tip.
Learned sonething todat 
Note that this is not a change in Homey. This behavior has always been this way: Advanced Flows that are not manually startable (= have no start/play button) are grayed out 
.
Only add the start button if you need it, either to start it manually (from the app or webpage) or by the Flow card “Start flow” in the Flow section of “Then”.
It’s even more detailed:
