Daily/Weekly/Monthly Consumption Issues from MQTT
When I look at the Daily, Weekly and Monthly Consumption values that I get from my Smart Meter via MQTT from the Glow IHD/CAD there is strange behaviour between 00:00 and 01:00.
Is anyone else able to look at these values? How does your data/ Smart Meter compare?
The Daily Consumption resets at 1am - that may just be summertime? (But my supplier definitely works my smart meter tariff from midnight 'local')

My weekly and month resets have a bigger problem in that at midnight they drop to a smaller value, then increase (as we use power) till 1am when they are reset to zero

My other issue is that my tarif changes five minutes late:

My tariff change is 8 minutes adrift, I think it only has to be be accurate to +/- 15 minutes but not 100% sure.
So I have done some detailed digging here and have now read the SMETS2 meter spec....yawn! Each meter has a randomised factor added to when it switches tariffs, from 0 to 30 minutes. I can't determine for how long this is fixed so all I can say is.
This is normal.
The delay could be up to 30 minutes.
There is no advance, only delay.
It may change in the future...
