Domoticz

Posted: **Wednesday 07 February 2024 12:59**

I am setting up an MQTT display (button+https://button.plus/). There are also physical buttons on this. I want to switch lighting with 1 button. E.g. with payload: {"command": "switchlight", "idx": 268, "switchcmd": "Toggle" }

However, I also want that when this switch (idx268) is switched in domoticz, an MQTT command is sent from domoticz that turns on the LED of this button so that I see that the relevant light is on (and vice versa).
I can control this LED via topic 'buttonplus/wk1/button/7/ledrgb' + the RGB number such as '8323072'.

What is the best (and easiest) way to switch this in Domoticz? Script? What should this approximately look like? Unfortunately I don't know enough about domoticz to come up with a good solution for this.

What happened with this: https://www.domoticz.com/forum/viewtopic.php?p=313495

You can make a dzvents script that sends mqtt payloads to your button plus based on the domoticz trigger device. Similar as the script you used in the previous topic

I listened to your advice and now use an execute shell. I use a script for each value. I tried converting such a script to this functionality:

Code: Select all

return {
    on = {
        devices = {
            'lamp keukenkast'
        }
    },
    logging = {
        level = domoticz.LOG_INFO,
        marker = 'template',
    },
    execute = function(domoticz, device)
        domoticz.log('Device ' .. device .. ' was changed', domoticz.LOG_INFO)
        domoticz.log(device.text)
        domoticz.executeShellCommand ( 'mosquitto_pub  -h 10.0.1.122 -p 1883 -t domoticz/out/ButtonPlus/wk7/btton/7/ledrgb/8323072 -m ' .. device.. '')
    end
}

However, this gives error messages, so I am doing something wrong somewhere.....

Error:

2024-02-07 12:43:38.196 Error: dzVents: Error: (3.1.8) template: ...e/pi/domoticz/scripts/dzVents/generated_scripts/test.lua:12: attempt to concatenate a table value (local 'device')

The RGB color number must also be sent as a 'raw' value, I don't know if this is done this way

Your device is an device object, So use device.name to log the device name in

Code: Select all

domoticz.log('Device ' .. device.name .. ' was changed', domoticz.LOG_INFO)

The same probably for the device in the mosquitto_pub command.

What is the correct mosquitto_pub command to make the button change color?
I suppose it should be something like

Code: Select all

mosquitto_pub  -h 10.0.1.122 -p 1883 -t domoticz/out/ButtonPlus/wk7/btton/7/ledrgb -m 8323072

or when rgb value as text

Code: Select all

mosquitto_pub  -h 10.0.1.122 -p 1883 -t domoticz/out/ButtonPlus/wk7/btton/7/ledrgb -m "8323072"

t=mqtt topic
m= mqtt message, so the value to be set onto the topic.

Additional I would advise you to use mqtt explorer were you can look to the mqtt topics and also send messages to test. https://www.emqx.com/en/blog/connecting ... t-explorer

I'm using mqtt explorer. With this command 'domoticz/out/buttonplus/wk1/button/1l/ledrgb' I can switch a buttonLed with the value ' 8323072' as a raw value.

I adjust my script:

Code: Select all

return {
    on = {
        devices = {
            'Lamp keukenkast'
        }
    },
    logging = {
        level = domoticz.LOG_INFO,
        marker = 'template',
    },
    execute = function(domoticz, device)
        domoticz.log('Device ' .. device.name .. ' was changed', domoticz.LOG_INFO)
        domoticz.log(device.text)
        domoticz.executeShellCommand ( 'mosquitto_pub  -h 10.0.1.122 -p 1883 -t domoticz/out/buttonplus/wk1/button/1l/ledrgb -m 8323072' .. device.name.. '')
    end
}

Nothing happened. I also tried:
'domoticz.executeShellCommand ( 'mosquitto_pub -h 10.0.1.122 -p 1883 -t domoticz/out/buttonplus/wk1/button/1l/ledrgb -m "8323072"' .. device.name.. '')'
Same result (my log says ' 2024-02-07 17:22:57.095 Status: dzVents: Info: template: nil'

I think I' almost there:
if I use in the sript:
domoticz.executeShellCommand ('mosquitto_pub -h 10.0.1.122 -p 1883 -t domoticz/out/buttonplus/wk1/button/1l/ledrgb/ -m "8323072"')

I get in mqtt explorer: 'domoticz/out/buttonplus/wk1/button/1l/ledrgb/ 8323072'
there are 2 spaces in between, maybe this is the problem my buttonled doesn’t switch on?
This is sent as raw data with ' -m'?

Posted: **Wednesday 07 February 2024 19:23**

Try
domoticz.executeShellCommand ('mosquitto_pub -h 10.0.1.122 -p 1883 -t domoticz/out/buttonplus/wk1/button/1l/ledrgb/ -m 8323072')

Posted: **Wednesday 07 February 2024 20:08**

that gives the same result:
domoticz/out/buttonplus/wk1/button/1l/ledrgb/ 8323072

Hi,
Try to remove the trailing slash:

Code: Select all

domoticz.executeShellCommand ('mosquitto_pub -h 10.0.1.122 -p 1883 -t domoticz/out/buttonplus/wk1/button/1l/ledrgb -m 8323072')

maybe you are publishing in topic domoticz/out/buttonplus/wk1/button/1l/ledrgb/<blank>

That do the trick. Many thanx! When I switch off the led does not switch. I have to send ' off' or '0' when off. Is there a way to combine this in one script?

Posted: **Wednesday 07 February 2024 22:03**

Just copy the execute shell command line and put the other mqtt command in it.

Posted: **Thursday 08 February 2024 11:24**

I combined these two execute shell commands with this script:

Code: Select all

return {
    on = {
        devices = {
            'device xx'
            }
    	},
    	execute = function(domoticz, switch)
    		if (switch.state == 'On') then
    		    domoticz.executeShellCommand ('mosquitto_pub -h 10.0.1.122 -p 1883 -t domoticz/out/buttonplus/wk1/button/1l/ledrgb -m 8323072')
    	        domoticz.log(device.text)
    		--	domoticz.notify('Hey!', 'I am on!',
    		--	domoticz.PRIORITY_NORMAL)
    		else
    			domoticz.executeShellCommand ('mosquitto_pub -h 10.0.1.122 -p 1883 -t domoticz/out/buttonplus/wk1/button/1l/ledrgb -m 0')
    		     domoticz.log(device.text)
    		--	domoticz.notify('Hey!', 'I am off!',
    		--	domoticz.PRIORITY_NORMAL)
    		end
    	end
    }

This works fine.

correction; it doesn't work very well anyway. I get an error in my log that I cannot explain:

Code: Select all

return {
    on = {
        devices = {
            'Beveiliging buttonplus schakelen'
            }
    	},
    	execute = function(domoticz, switch)
    		if (switch.state == 'On') then
    		    domoticz.executeShellCommand ('mosquitto_pub -h 10.0.1.122 -p 1883 -t domoticz/out/buttonplus/wk1/button/1r/ledrgb -m 8323072')
    	        domoticz.log(device.text)
    		--	domoticz.notify('Hey!', 'I am on!',
    		--	domoticz.PRIORITY_NORMAL)
    		else
    			domoticz.executeShellCommand ('mosquitto_pub -h 10.0.1.122 -p 1883 -t domoticz/out/buttonplus/wk1/button/1r/ledrgb -m 0')
    		     domoticz.log(device.text)
    		--	domoticz.notify('Hey!', 'I am off!',
    		--	domoticz.PRIORITY_NORMAL)
    		end
    	end
    }

Error:

What does this mean/what am I doing wrong?

The script also keeps running continuously and that is not the intention. The script only has to do its work in the event of a switch state change.....

Posted: **Monday 12 February 2024 16:33**

The error is referring to line 15 (buttonplusled1r.lua:15) wich probably is the line

Code: Select all

domoticz.log(device.text)

You have that 2 times in your script. But "device" is not known in your script. so nil value, as you you execute the script with

Code: Select all

execute = function(domoticz, switch)

you better change that in

Code: Select all

execute = function(domoticz, device)

Posted: **Monday 12 February 2024 16:36**

additional: device.text will also give an error because it should probably be device.name (String. Name of the device)

thx, I adjust the 'switch' function.

This is my script now:

Code: Select all

return {
    on = {
        devices = {
            'Beveiliging buttonplus schakelen'
            }
    	},
    	execute = function(domoticz, device)
    		if (device.state == 'On') then
    		    domoticz.executeShellCommand ('mosquitto_pub -h 10.0.1.122 -p 1883 -t domoticz/out/buttonplus/wk1/button/1r/ledrgb -m 8323072')
    	        domoticz.log(device.text)
    		--	domoticz.notify('Hey!', 'I am on!',
    		--	domoticz.PRIORITY_NORMAL)
    		else
    			domoticz.executeShellCommand ('mosquitto_pub -h 10.0.1.122 -p 1883 -t domoticz/out/buttonplus/wk1/button/1r/ledrgb -m 0')
    			domoticz.log(device.text)
    		--	domoticz.notify('Hey!', 'I am off!',
    		--	domoticz.PRIORITY_NORMAL)
    		end
    	end
}

With this code it looks like the 'off' function keeps repeating:

Is there a way the script does nothing until the state of 'Beveiliging buttonplus schakelen' is changing?

Posted: **Thursday 15 February 2024 10:21**

according your script it should only be triggered when device 'Beveiliging buttonplus schakelen' is being switched.

PS
you still have a message like 2024-02-15 09:38:37.393 Status: dzVents: Info: nil
this is because of the lines
domoticz.log(device.text)
that should be changed into
domoticz.log(device.name)
as device.text is nothing..... so nil.
