If the data on your Eve Energy Strip accessory displayed in the Eve app is incorrect, pull it out of its power outlet, wait 15 seconds, and then plug it back into the power outlet. This partial reset may solve some problems.
If this doesn't help, then you can use these steps to do a hard reset:
1. Plug Eve Energy Strip into a socket and wait until the 3rd LED power button stops blinking
2. Press the 1st and 3rd LED power buttons at least 10 s, until the 3 LEDs blink
3. Release the power buttons and wait until all LEDs stop blinking
