Serial

  • Type : string

Unique sensor serial number, if supported or required by channel type.

Channel

  • Type : string

Resolution

  • required
  • Type : numeric

On data readout the stored/calculated reading will multiplied with this factor.

Unit

  • Type : string

Numeric

  • Type : numeric (boolean)

Channels can have numeric or alphanumeric data.

Offset

  • Type : numeric

This offset will be applied during data storage to the actual reading values to correct them.

Adjust

  • Type : numeric (boolean)
  • Default : 0

Adjust channel offset (for meter channels only) automatic, if the actual reading value is lower than last reading but <> 0.

Use this, if your measuring equipment sometimes looses/resets its counter.

Cost

  • Type : numeric

Cost per unit, for meter channels only.

Threshold

  • Type : numeric

A reading is only accepted, if the value is ± threshold from last reading, only relevant for writable channels.

Valid from

  • Type : numeric

Readings are only valid if they are greater or equal this limit.

For writable channels invalid values skipped on saving, for calculated channels they will be skipped on readout.

Valid to

  • Type : numeric

Readings are only valid if they are lower or equal this limit.

For writable channels invalid values skipped on saving, for calculated channels they will be skipped on readout.

Public

  • Type : numeric (boolean)
