HA sensor entity - change time (timestamp)

[ender001]

Hi,
I would like to ask you for help with Home assistant sensor entity in Node-red. I’m reading Energy data from source where the values are with 30-60 minut delay. I would like to save the values into HA database without this delay. Is there any posibility to overwrite the actual time (timestamp) in Sensor entity?

Not really possible.
HA saves the values to its database on receiving them regardless of what data there is in the state and attribute fields.

Please vote for this feature request, so we in the future might be able to do it.

Import old energy readings for use in energy dashboard

I am a homeassistant enthusiast since about 4 years and have been using Emoncms now for about 7 years. As homeassistant is now able to show historic energy usage it would be great if I could import historic data into the energy dashboard so that I can kill all legacy systems and have 1 holistic view of my energy consumption. Couldn’t care too much about the way it would allow me to import that data (excel, CSV, SQL) as long as it would be possible.

Thank you WallyR,
I voted and I hope they will implement this feature in near future :).
