My offering here is nothing new.... A humidity sensor in my garage used with a Kasa smart plug to run a dehumidifier when it gets humid, using Ernie's Smarter Humidity Fan Community App. As an added extra, I use the switch option in the app, then use the Energy Monitoring of my Kasa plug to monitor for lower power usage than expected, triggering a non-committal notification that the Dehumidifier "may be full". Also using @bertabcd1234 's notification proxy, unrelated to this topic, but another great option for those running multiple HE hubs.... I just need to use it more than I do....
