Opus/Imagintronix XT300 Soil Moisture implementation

[Nettime]

Ok thought I'll have a go at this but seem to run in to dead ends.
As current there is no Domoticz device that fits the sensor if used with rtl_433.
The sensor have Air Temperature (not a problem) and Moisture 99-0%.
Which wont work with the Domoticz moisture device which has 0-200cB.
With rtl_433 only the temperature device is created.
The obvious fix would be to create a new device type for this sensor but that is not sustainable in the long run.
My thought was a new custom sensor that takes 2 values and 2 units. Something like
nValue: 0, sValue: "floatValue1";"floatValue1, Options: {'Custom': '1;<axisUnits1><axisUnits2>'}
Another thought would be to update the existing moisture device to handle "%"
Would also require rtl_433 to be able to create and handle 2 devices, which should not be a problem with idx+1.

Any thoughts?

As in my opinion Domoticz is heavily legacy ridden would not a few more custom sensors be a good idea?
