Integration Threshold - supporting attributes

Currently the THRESHOLD integration works fine for states.

Example to monitor the daily DSL speed minimum lower then 100 MBit/sec:

- platform: threshold
  name: "SHS Dsl Speed Min"
  entity_id: sensor.network_download_24_hours_min
  lower: 100

Would nice to have something like
attribute: <attribute of a sensor> with default "state" if missing

Did you find any workaround to do this? I would like to have a threshold sensor based on the brightness of a deconz group.

I dont use tthreshold anymore but I guess you can create a template sensor with state equal to the attribute of your original sensor and use that in the threshold helper.
