I have two S220 battery doorbells that have given me very few issues for the better part of a year. In the last week both have drained seemingly instantly at different locations. They don’t have a lot of detections. They are both connected to Homebase in their respective locations. Indoor wired C220s working fine on same connections and systems. Unfortunately can’t get to them for a month because they are in remote locations. What happened?
