stock template does not work with Tesla Virtual Power Plant #99

Open neildsb opened 2 years ago

neildsb commented 2 years ago

Magnificent work, I have a little bug, the animations and figures do not work when exporting the battery to the grid; hope this helps?

Hmm, can you post your card config? And maybe also your templates?

neildsb commented 2 years ago

I have the stock templates, I think basically it struggles with battery to grid concept -

template:

reptilex commented 2 years ago

The custom template does not have a tesla_card_battery_to_grid entity and doesn't have a configuration for the card to do this. I have no tesla powerwall therefore I cannot give you any indications. Please ask in the forum. Or look at my post, I think somebody already solved it there.

@neildsb left comments with a solution to this in the issue around it stopped working from core 2022.2.

reptilex commented 2 years ago

@Avatar1976 which template of that thread should I use to update the docs?

purcell-lab commented 2 years ago

This issue isn't confined to just VPP users, outside of the US many times your powerwall can export directly to the grid.

Fortunately help is at hand and https://github.com/AviadorLP has solved this issue for us at #96, though a complex set of templates which map the flows dependent on input/export & charging/discharging states.

I have now adapted this for the powerwall and my templates and configuration is below, which now correctly shows grid2battery and battery2grid flows and should work without modification for other powerwall users.

# Templates for Actual Powerflow transfer charts (APF - Actual PowerFlow)
#
# For the math to add up a new Real House Load must be calculated and used, witch includes
# the inverter consumption and excludes rounding errors and corrects inaccurate power readings.
#
# It never made sense that inbound power sometimes does not equal outbound power. This fixes it!
#
# Developed by AviadorLP
#
# Just replace the 4 words below "ReplaceWithYourSensor" with your specific sensors,
# for grid, house, solar and battery entities, example "sensor.powerwall_load_now" 
#
# If your sensor is negative when it should be positive replace that complete line with
#         state: "{{ 0 - states('ReplaceWithYourSensor')|int(default=0) }}"
#
# If you don't have a battery replace that complete line with
#         state: "{{ 0 }}"

sorry for so many questions, how did you display the kWh in the bubbles?

purcell-lab commented 2 years ago

sorry for so many questions, how did you display the kWh in the bubbles?

No problem.

You create three utility meters which reset daily, this is now easy with the new helpers; solar production, house consumption and grid consumption. Then use those new sensors for the extra_entity text which displays at the top of each bubble.

thank you so much!! RTFM Neil - it's all in the readme, I have also copied your display parameters by showing Watts over kW
