⚠️ Potential issue | 🟠 Major

Constrain the humidity offset range to prevent invalid values.

The offset range of -70.0 to 70.0% could produce invalid humidity readings outside the valid 0-100% range. For example, a 50% humidity reading with a -70% offset would result in -20%, or an 80% reading with a +70% offset would produce 150%.

Consider reducing the range to -50.0 to 50.0 (or even -30.0 to 30.0) to minimize the possibility of invalid values.

In @Integrations/ESPHome/Core.yaml around lines 174 - 187, The humidity offset
sensor (platform: template, name: SCD40 Humidity Offset, id:
scd40_humidity_offset) allows an excessively large range; change its min_value
and max_value to safer bounds (e.g., set min_value to -50.0 and max_value to
50.0, or -30.0/+30.0 if you prefer stricter limits) so offsets cannot produce
humidity readings outside 0–100%; keep all other properties (restore_value,
initial_value, unit_of_measurement, step, mode, disabled_by_default) unchanged.
