How to scrape humidity only from wtgr800?

Good Morning,
is it possible to only scrape the "humidity" from a WTGR800 sensor?
i can't find it on the forum, nor the internet.
I want to make a irrigation system with it, so need some (variable?) values in blocky to turn on/off a (virtual switch) watervalve.

Hello,
you may find examples here
https://www.domoticz.com/wiki/Smart_Lua_Scripts
I use :
Code: Select all
smoistsensorTemp, smoistsensorHumidity = otherdevices_svalues["TempHum1"]:match("([^;]+);([^;]+)")
debug("-- Irrigation ==> [TempHum1] - Soil Temperature: " .. smoistsensorTemp .. " ")
debug("-- Irrigation ==> [TempHum1] - Soil Humidity: " .. smoistsensorHumidity .. " ")
See ya, GD

Hi George, i've looked into there but that's not very easy

Sorry,
debug is a function of mine, you can replace it with print to see the values in "Setup / Log" of Dz.

2016-04-24 11:31:05.661 (rflink) Temp + Humidity (Grondvochtigheid)
2016-04-24 11:31:05.856 LUA: -- Irrigation ==> [TempHum1] - Soil Temperature: 17.0
2016-04-24 11:31:05.856 LUA: -- Irrigation ==> [TempHum1] - Soil Humidity: 99
okay, it seems that it prints the output, but now i want it to an (virtual) device so i can use it in blocky!
thanks

Why is it so hard to export a variable value to an (virtual) device, so i can switch on/off things when a value is to low or to high..?
maybe i need to work with variables?
anyway, this drives me really crazy.
working with temperatures in blocky is no problem at all, but for humidity it doesnt work

This is the result if you
where xxxxxx is the idx number of my wtgr800 connected via RFLink
Code: Select all

In my Frontpage.html (by G3rard) I just grab the field "Humidity" and "Temp" to get a number only value.

@BarryT
Just wondering about your question:
1) Is the humidity-sensor of wtgr800 showing itself under Dashboard/ Devices (possibly in combination with Temperature)?
2) Subsequently (when activated under Devices), does the humidity-sensor of wtgr800 then show itself under the list of 'blocky'-elements?

1) Yes it is showing itself, indeed with combination temperature.
I just want to have them as "single" values in a dummy.
2) Yes i seen them in blocky, ofcourse as single ones (temp and humidity).
I just want to have the values as single ones.
I have many devices, and the temperature and humidity takes up much space in the (index) layout of my mobile device.
