DM Dots - Battery Life Estimator
Battery life calculator for the DM Dots

Battery life is extremely important for Bluetooth tags like the Dots, which are sealed and “deploy once”.
The battery voltage of the Dot Tags, Glows and Sensors is reported in the payload, together with a VBatt Good status flag, which is also reflected in the mobile app. The flag is set to 0 when the battery voltage falls below 2.7 V, and set back to 1 if the voltage recovers above 2.7 V.
See more info on the status flags here:
With our Digital Matter Wireless Provisioning Tool, you can adjust the Dots’ parameters to get the most out of your devices. See the effect of your parameters using the Battery Life Estimator below.
Note: This estimator currently models the DM Dot Tag only. It does not account for LED use on the DM Dot Glow, or sensor sampling on the DM Dot Sensor, both of which will reduce battery life. Please also note that battery life estimates are influenced by several factors, including parameter configuration, temperature, installation of the device, sensor sampling, accelerometer settings, and more.
