Domoticz

Hi,

I have a Soil Moisture device using Mysensors Arduino code, this shows up in Domoticz as a soil moisture sensor with no issues (see JSON output below).

I've been trying to read the sValue in a separate script using LUA to export this value to a txt file for another purpose. Unfortunately the code will return a 'nil' value using this line of code:

sSoilmoist = otherdevices_svalues[soilmoist_dv]

(soilmoist_dv is declared as my soil moisture device name).

I notice in the devices 'show current state' this device has no sValue so i assume this is the issue. Is there another way to extract the value or get better still get the sValue populated? Can anyone help please?

Something like this? (Don't forget the ' ' )
sSoilmoist = math.floor(tonumber(otherdevices_svalues['soilmoist_dv']))

thanks - just tried that and the script returns much the same as before;

Seems that sValue is null or blank. I may have to change the device to 'humidity' to get around this.
