FAQ: How Sleepy Devices Report Battery Life (tier reporting)

Many battery-powered " sleepy" devices reports battery levels in tiers. The exact tiers will vary by device. For most contact sensors, the tier that is reported as “88%” really means “above 87% and below 100%” So as soon as battery level drops below 100%, even to 99%, it will likely be reported by SmartThings as 88%, although the exact buckets vary by DTH/Edge Driver. What you need to watch is the trend. If it drops 10% in one day. That was probably just a tier drop. You can even bounce back-and-forth by 10% because it’s right at the threshold of a tier. But if it’s dropping 10% every week, that’s a different problem. If you’ve had any device off-line for a while, it’s really common for it to come back in the next lower tier, which looks like a 10% drop but might’ve been a drop of ha…
