I would expect these to be on continuously, but we have 30 minute gaps with zero draw.
(Granted, this is just a “detected device” and I really would need some current clamps on that circuit to tell the whole story. Since I have also solar, there is no spare. As has been discussed before, we really need a viable option to monitor such circuits directly. (I do have a handheld clamp meter, maybe I could do some casual tests)
