The following two files are updated to support both operation mode changes and battery reserve percent changes.
All the other files are identical to the excellent post of @estebanp from above.
The first, services.yaml, needs to be put into /custom_components/tesla_gateway:
set_operation:
description: >
Changes operation mode
fields:
real_mode:
description: Mode to set to the Tesla gateway.
example: 'self_consumption, backup'
set_reserve:
description: >
Changes battery reserve percent in self_consumption mode
fields:
reserve_percent:
description: Percentage of battery reserve
example: 70
The second, __init__.py needs to go in the same directory:
"""
Monitors and controls the Tesla gateway.
"""

That’s it! One thing to note is that if you use these and the Tesla app doesn’t show any changes, try killing and restarting the app. The Tesla app caches old values and so even if the changes happen you won’t see them unless you exit and restart the app.
