Measurements
Overview
Haltian Field displays real-time and historical sensor measurements for each device. The measurements shown on the Device Details screen depend on the selected device — the app automatically displays all measurement types that the device reports.
Different devices support different measurements. For example, an environmental sensor may show temperature, humidity, and CO₂ readings, while a presence sensor shows occupancy status and movement counts. Device health measurements like battery level and boot count are common across most device types.
Check the device specifications for your specific device model to see which measurements it supports.
