INFLEXIBLE_DEVICE_SENSORS
=========================

[Deprecated field] Power sensors representing devices that are relevant, but not flexible in the timing of their demand/supply.
To avoid using the field, use ``inflexible-consumption`` and/or ``inflexible-production`` instead, which make clear the sign convention.
For this field, each sensor's sign convention is determined by its ``consumption_is_positive`` attribute (default: false, i.e. production-positive).
Must be a list of integers.
