sensor.py - RuntimeError: dictionary changed size during iteration

[larobo]

When the pop() runs from the code below:

sensor.py:
        for measurement_time in self._measurements.keys():
            if measurement_time < (now - self._period):
                _LOGGER.debug(
                    "period_rain update_data_from_sensor removed (%s: %s)",
                    datetime.fromtimestamp(measurement_time).isoformat(),
                    self._measurements[measurement_time]
                )
                self._measurements.pop(measurement_time)
            else:
                total += self._measurements[measurement_time]

you get the exception:
RuntimeError: dictionary changed size during iteration

A possible fix is:
for measurement_time in list(self._measurements.keys()):
