customicon script Topic is solved

[jarmoboy]

Can someone help me to make script in LUA which changes icons?
device is general custom sensor with idx 118 and it can have value from 0 to 100.
I want to have for example: if value is > 20 and < 40 than set custom icon 115.
Is it even possible? Iam looking for it for ages but my knowledge of scripts is poor.
Thanks

Hi jarmoboy,

yes that's possible and no big problem, i've done this often. Just give a few informations more please....

Should the custom sensor show percentage? And the icon? Battery load?
How is the device triggered? (At this trigger the icon should be triggered, too.)

See an example here:

Exactly, is percentage of battery from robot, data are evaluated from nodered and exactly this icons I have already in domoticz. So I need only example for one case and the other cases (percentage state) I can evaluate and edit myself. I need only the main code to change the icon.

[bewo]

Ok... I use the icons for mixed things. One of this is a vacuum robot. See script details (if needed here): https://www.domoticz.com/forum/viewtopi ... 47#p232887

Here's the piece of code for set different icons:

Code: Select all

-- Batteriestatus (Symbol und Stand) aktualisieren:
        
        batterie_device = Roboter.Name..' Batteriestand'
        
        -- Passends Batterie-Icon festlegen:
        if Batterieprozent <= 20 then
            batteriesymbol = '102'
        elseif Batterieprozent > 20 and Batterieprozent <= 50 then
            batteriesymbol = '104'
        elseif Batterieprozent > 50 and Batterieprozent <= 90 then
            batteriesymbol = '101'
        elseif Batterieprozent > 90 then
            batteriesymbol = '103'
        end
        
        -- Batteriestand schreiben
        if Batterieprozent ~= tonumber(otherdevices_svalues[batterie_device]) then
            commandArray[#commandArray+1] = {['UpdateDevice'] = otherdevices_idx[batterie_device]..'|0|'..Batterieprozent}
            print('Staubsauger-Roboter: '..Roboter.Name..' -> Batteriestand auf '..Batterieprozent..'% aktualisiert.')
            os.execute('curl "http://localhost:8077/json.htm?type=setused&idx='..otherdevices_idx[batterie_device]..'&name='..Roboter.Name..'%20Batteriestand&description=&switchtype=0&customimage='..batteriesymbol..'&devoptions=1;%25&used=true"')
        end

If there's a question - just ask.

Hi Bewo,
this topic iam examination whole month and piece of code you gave me I was trying to use yesterday. There is so many variables and things which I don't understand so I wasn't successful at all. BTW. This piece of code you gave me is depended on the other part of lua which work together with this script. After several issues(koalazak plugin made my domoticz crash once a day) I have decided I don't need to control the robot, I want only read the state so I dismissed the plugin and use only nodered to read from API. Honestly, I need something simple and more user friendly. Thank you

[bewo]

Hi jarmoboy,

you don't have to use any plugin. You've asked for an piece of code for self construct. There it is (was).

You need a kind of trigger to set the icon. So i thought the right moment is, when a new battery value is reported. There you could integrate the code piece.

But if you don't like to or it's not possible...:
It's even possible to trigger the script once a minute (time trigger), in worst case there's a false icon for an minute.
Would that be ok for you? If yes i would write this few lines of code for you, no problem.

[jarmoboy]

If you can.... It would be great

[bewo]

If i don't forget something..... Here it is:

Generate a new Lua-Script, device triggered (So the icon should change immediately. )

Please change the variables - try out and report.

Code: Select all

-- Set your devices and variabels here:

Icon_Nr_ORANGE = '123'  -- ORANGE = low
Icon_Nr_YELLOW = '123'  -- YELLOW = ok
Icon_Nr_GREEN = '123'   -- GREEN = full

-- Your Domoticz Port in URL (default: 8080)
Domoticz_Port = '8080'
-- Load the domoticz LUA library (Change the path only; default at raspberry is /home/pi/domoticz/scripts/lua/JSON.lua)

    end
	return str
end

BatteryLevel = tonumber(otherdevices_svalues[Device])

Did you set up as device triggered?

Please read again I made edit. Thx

[bewo]

A sorry my bad... I've didn't seen...

Make sure that localhost has the rights to collect the json.
Therefore you have to set localhost (127.0.0.1) in your settings under local network:

[jarmoboy]

I have add it but still says the same...

[jarmoboy]

Is there something i can write to command line to find out why is unauthorized?
THX

[bewo]

Sorry the delay...

Did you restart Domoticz after add 127.0.0.1 in the settings? Sometimes there some network issues...

Yes, you can test this in CLI. In your case type:

Code: Select all

curl "http://127.0.0.1:8084/json.htm?type=command&param=getversion"

And you should get some information about domoticz version.

[jarmoboy]

HI,
No preblem, i've got info about version, so it works.

[bewo]

And the script still doesn‘t work?

If not, maybe your network is not well configured.
Please change in my script „localhost“ to „127.0.0.1“. It‘s near under „Look for the icon which is used in the moment“

[waaren]

And the script still doesn‘t work?

Are you aware that you could use dzVents and apply the method setIcon(iconNumber) ?

[jarmoboy]

Tadaaaaa, it works,
Problem was "localhost". When i replace it with 127.0.0.1 everything works.
Thanky you Bewo for you magical skills.
So for further use and others iam including working code:

one more thing, iam perfectionist...
ive tried myself to use the code also for text device, ive checked few step with "print" to check if it uses right icon it says it does but it doesnt.
What is wrong there?
