I’m trying to setup Enphase (with the integration) to monitor my Solar Grid im/export and house Consumption. The numbers look off (like the spike from 1-2am) im not sure I have the right metrics plugged in the right places. i did try this Enphase tutorial but i feel this is headed down the wrong path or maybe this is the reason its reporting weird.
Can it be you configured the Envoy Today values in the HA Energy dashboard? If so, change the ebergy dashboard to use the Envoy Lifetime values. The Today values get reset at 1 am during daylight saving time period which results in the spikes as shown in your picture.
