I think that the consumption since midnight is what’s measured by the AMS and read by the Pulse. The calculation in Homey is based on the live watt info from the Pulse. But its not completely live, it updates about every 30sec. If I go to the Tibber app witch updates about every second, I can see the watt fluctuates very much within those 30 seconds that Homey updates. I think that’s why there might be a difference.
