Some time last night, my airconditioning flow stopped working. I wanted to have a look at it today, but if I try running it I get an error saying “Invalid arguments”. If I try to save it, I get the same error. The only way I can get the flow to partially run is right clicking one of the later cards in the flow and select run from here.

Anyone here know how I can find the culprit? There’s nothing in the normal log. I’m pretty sure something’s broken in power by the hour, but until I’m sure I would rather not change the flow too much.

Thanks!

Maybe there is something changend in a flowcard? A non existing value?  
This link is in Dutch, maybe you can do something with it.

Thanks, this was the first thing I started looking for - but what I _didn’t_ look for was that power of the hour no longer supports “20 lowest”. It can now at most do “16 lowest”, and that triggered the error. Thanks 🙂
