BL had an article about the AMS humidity sensors awhile ago. They changed it from reporting a % value to the current graphic. IIRC, they said the AMS reads several sensors and from those readings create the bar graph you see. As for the cheep hygrometers you can get on Amazon, they don’t read below 10%. So getting a 5 on MQTT means the AMS is doing good for humidity. Anything less than 3 indicates it is time to change the desiccant.
