home-assistant-rest-sensor.yaml

# Home Assistant REST integration for Pylon-Monitor (Pylontech battery monitoring)
# No MQTT broker required - Home Assistant polls the device's built-in JSON API directly.
# The device's own Settings page generates this block for you with your current IP
# pre-filled; this is the generic form. Replace <DEVICE-IP> below.
#
# Note: if you already use MQTT auto-discovery (recommended, 10 sensors, zero YAML),
# do not also add this REST block for the same values - you'll get duplicate entities.
