The separate transformer for my doorbell / house number light stopped working. My Rachio was mounted just a few feet away, so I wired them to my Rachio3 in unused zone12. Then I set a schedule to run that zone daily at sunset for 5hrs. Valve monitoring (open circuit monitoring) also helps. This seems to be working great for a few months. I’m sure the small but extra load on Rachio’s transformer would void any warranty, yet we’re years beyond that. My Eufy doorbell also has a battery, but this seems to help keep it charged with just 5hrs per day.
Anyone else found other non-recommended usages for their out of warranty Rachio controller?
