Eve makes smart home hardware that measures rather than simply switches. The Energy plug meters what the appliance plugged into it actually draws, which is how a fridge or heater quietly running up a bill gets found. The Door and Window sensor reports open or closed rather than just detecting movement, so a locked-up check gives a straight answer. The Thread version of the Energy plug joins a low-power mesh instead of leaning on Wi-Fi. In a small office both earn their keep on after-hours checks.
