The only view I’d trust
(Not all, 3 out of 4 of mine are, idk why) AMS 2 Pro RHs can be a bit BS. “3%” is more like 12%. “0%” means “below 10%”. I’ve worked with these Zigbee/Apple Home ones long enough against other humidity sensors that I can trust them better. Just make sure no desiccants are directly next to it.
