Hello, I'm a bit stumped on this one. My skimmer is currently stuck in the off fallback state. I can manually turn it on but I don't like to do that because I have an external collection cup.

The skimmer should turn off when the skim collector input is wet or when the return pump is off. Currently neither of those are true so I'm not sure what fallback is being activated.

I added some screenshots of the inputs/outputs. Am I missing something?

See your If Input / Dependency Unavailable setting? It's Off. That means if either skim collector or Varios Return are unavailable for some reason the skimmer will goto FALLBACK OFF. If that setting were On then skimmer would have gone to FALLBACK ON. But don't just change it because that'd mask a problem. The skimmer is off because there is something wrong with either skimmer collector or Varios Return or both. Could be Varios Return experiencing Check Pump (..typically power or cabling issue...). Can't tell because it's not included in your screenshots. If you share the status and config we can help out a bit better.

Looking at it closer, think it is your skimmer collector causing the problem. The skimmer output is expecting a wet/dry condition but you may providing it an on/off condition. Or it may specifically be expecting a level sensor and rejecting the 0-10V even if the correct condion is sent. At least assuming you are using a DIY float switch with 0-10V input. Try sharing that input config. Something there just doesn't look quite right. This may end up being something you need to refer to supoort.

Thank you for the reply, it seems like the fallback cleared up overnight. I tested the float switch that should shut down the skimmer and it seems to be working. I'll just keep an eye on it, I made a few changes yesterday so I'm guessing everything just needed to settle?

It typically shouldn't need time to settle but the sensor and output states are shared between the multiple collective members and possible something wasn't shared properly or simply wasn't shared at all. If either were to happen and your input and output are on different controls that would definitely explain. Not something common but have seen similar before. If you experience similar again, try rebooting collective master as your last troubleshooting step. Not the entire collective, just master. This may clear the issue as master is responsible for monitoring inputs and making control decisions then instructing others what to do with outputs. Other controls only act independently in a failure situation.
 
Figured it out, when I added the wave engine to the collective it seemed to have moved all the 0-10v inputs (just 2) to the black wire. I still can't explain it but my sump lights were not coming on so I looked and it was "off fallback". I moved the switch to the right wire in settings and everything is back to normal.
