here is the explanation:

Hub Firmware 18.x Beta

This is going to be a little long but I’ll try to explain what’s going on here. The percentage is calculated based on the battery voltage reported by the sensor. Previously a voltage of 3.0V was considered 100% and 2.1V or below was considered 1%. We did make some changes to the voltage reported by the sensor and yesterday we released changes to the SmartSense Multi Sensor and SmartSense Motion Sensor DTHs to adjust how that voltage is converted to a percentage. We made these changes in an attempt to improve the accuracy of the battery percentage reporting to the extent possible given the hardware design and the battery technology. The SmartSense Motion Sensor requires at least 2.4V to operate all the components in the sensor. The DTH change we released yesterday reports 2.4V as 1% ins…
