Energy & EV

Blueprints for energy monitoring, EV charging, and battery management.

EV Smart Status

Aggregates EV battery, charger connection, and energy prices into a single actionable status.

States

State	Condition	Action
CHARGE_NOW	Plugged in + (Low Price OR Excess Solar OR Critical Battery)	Start charging
STOP_CHARGING	Plugged in + High Price + Battery has buffer	Pause charging
PLUG_IN	Home + Low Battery + Disconnected	Connect charger
FULL	Battery at 100%	Charging complete
IDLE	Disconnected with sufficient charge	No action needed

Inputs

Input	Description
car_battery	EV battery level sensor (%)
charger_status	Charger connection status
grid_price	Energy price sensor (optional)
solar_power	Solar production sensor (optional)
min_battery	Critical battery threshold (force charge)
max_price	Maximum acceptable price threshold

EV Charging Logic

Automation blueprint for smart EV charging based on solar/grid conditions.

Features

• Starts charging during cheap rate periods
• Charges on excess solar production
• Emergency charge when battery critical
• Pauses during peak pricing

Battery Status

Monitor device and home battery levels.

Features

• Multi-level battery status (Good, OK, Low, Critical)
• Outage tracking
• Last charged timestamp
