Just started using Homey Flow and Advanced Flows. Trying to get Homey to reset zwave energy meters to zero at midnight and I keep getting flowcard\_not\_registered error. Any ideas what that means and how to fix this error? Thanks ---

It is a bit of guessing if you don’t share the flow right away. Thanks 🙃 Maybe it is a syntax error, or something in the zwave app’s code. ---

Aha, I suspect it is in the App code. I’ll just send a zwave string to do an energy reset. I thought the error was something more fundamental, you have tweak the bidet before you use a flow type of thing. No problem workaround exists.
