Script to send value from one domoticz to another one

[tage]

Is it possible to make a script to send a temp value or rain or wind etc to another domoticz on a easy way? I know it is possible to connect domoticz together but I just want to send a few values to a friends domoticz. An mqtt broker are also able to use if it makes it easier...

Yes is possible:

My first option would be to use a JSON-API Look here from a dzVents script using the domoticz.openURL() command

[tage]

Aah that sounds easy

/json.htm type=command&param=udevice&idx=IDX&nvalue=0&svalue=TEMP

But how do I get my value in to that "temp" ?

In its most basic form (dzVents script)

Spoiler: show

Code: Select all

 --[[ 
 jsontest.lua 
 ]]-- 

return {

on = { devices = {'temp deviceName'}},
    
    execute = function(dz,trigger)
    local myURL   = "http://xxx.xxx.xxx.xxx:yyy/json.htm?type=command&param=udevice&idx=nnn&nvalue=0&svalue=" .. tostring(trigger.temperature)
    
          dz.openURL({
                                    url = myURL,
                                    method = "GET",
                                    callback = "only needed when you want to check the result" })    

    end
}

You could do this in a bash script:

Code: Select all

Temp=$(curl -s "YOUR_DOMOTICZ_SERVER/json.htm?type=devices&rid=TEMPERATURE_DEVICE_IDX" | jq '.result[0].'Temp'' | tr -d '"')

it produces a clean temperature in format XX.X
then you can sent it to your friend:

Code: Select all

curl -s "YOUR_FRIENDS_DOMOTICZ_SERVER/json.htm?type=command&param=udevice&idx=FRIENDS_DEVICE_IDX_HERE&nvalue=0&svalue=$Temp"

In short, retreive your value, sent it to your friends domoticz.

But why the hard way? you also would have to make a planning for say every five minutes sent an update (run the script), while this can all be done with the domoticz connection (make new user for your friend and limit his acces to the temp device you want to share).

thx for helping me.. did a quick test and the dzvents script didnt work i got this error :

Code: Select all

2018-05-18 06:37:44.278 Error: EventSystem: in /home/pi/domoticz/scripts/dzVents/runtime/dzVents.lua: /home/pi/domoticz/scripts/dzVents/runtime/EventHelpers.lua:567: attempt to concatenate local 'vv' (a table value)

guessing it is for i dont use beta version ?
have not try the bash script but should not be to hard to try that

More than likely. openURL is part of dzVents > 2.3.0
Would be moving to Beta an option for you ?
Moving is a relatively easy step and providing you have a backup (and tested the restore) without a big risk.

Upgraded to beta and it seems to work
And the script also working ! Thx.
Is it possible to lower the decimals of the value ?
Right now it is like this : 18.3212456
18.3 should be enough.

@tage

Sure, change

Code: Select all

tostring(trigger.temperature)

to

Code: Select all

tostring(dz.utils.round(trigger.temperature,1))
