Smart Led Messenger

[laco]

I bought Smart Led Messenger. Someone can tell me how to set them up in DOMOTICZ.

I want to see the temperature, the clock, the on / off switch, and more.

Hi,

This Page (in French) says that you can send your text using

http://ip_address/?message=TEXT&intensity=AA&speed=BB
where ip_address is the ip of your messenger
TEXT = the text you want to display
AA = the brightness
BB = the scroll speed is the how fast your text moves

So, with this you can use your favorite scripting language to get the info from Domoticz and send it to the smart led messenger

[laco]

Can also be used in blockly?

[elmortero]

I never tried that, but according to this topic https://www.domoticz.com/forum/viewtopic.php?t=17006 it should work

With dzvents and bash I could help you but not blockly.

[laco]

Thank you it works for me perfectly. As it moves, it sends the text to the messenger and displays the digital clock sleep after 5 seconds.

Now I need to figure out how to send the temperature information. This may require a script.

[laco]

Can you please create a script that sends temperature information every 5 minutes?

[elmortero]

The script I am posting is for dzVents.
I understand that you are not yet familiar with it so please read these hints from waaren

by waaren
using dzVents would be an option. See below how that could look like. From your profile I cannot see which domoticz version you use.

When not yet familiar with dzVents please start with reading Get started Before implementing (~ 5 minutes). Special attention please for "In Domoticz go to Setup > Settings > Other and in the section EventSystem make sure the checkbox 'dzVents disabled' is not checked. Also make sure that in the Security section in the settings you allow 127.0.0.1 to not need a password. dzVents uses that port to send certain commands to Domoticz. Finally make sure you have set your current location in Setup > Settings > System > Location, otherwise there is no way to determine nighttime/daytime state."

More info on dzVents:
https://www.domoticz.com/wiki/DzVents:_ ... _scripting

This script (change to match your setup):

Code: Select all

return {
	on = {
		timer = { 'every 5 minutes'}
	},
	
	execute = function(domoticz, triggerItem)
	local smart_led_ip = '192.168.1.28' --replace by the ip address of your smart led messenger
	local static = 1 -- change to 0 if you want scrolling text
	
	local sensor = domoticz.devices('thermometer') -- replace thermometer by the EXACT name of your sensor
    	local tempe = sensor.temperature
	
	local url = 'http://'..smart_led_ip..'/?message='..tempe..'&static='..static
	domoticz.openURL(url)
	--domoticz.openURL('http://'..smart_led_ip..'static=0&local=0').afterSec(30)
	-- remove the -- from line above if you want to turn off the screen after 30 seconds
	end
}

Please let me know if you know more command, I have ordered a Smart Led Messenger too

It works great. Displays the temperature to 10 decimal places. This should be rounded to 1 decimal place or not. It would be good to add text about what temperature it is, exterior or interior.

Thank you very much for the great work.

1: easy: change "local tempe = sensor.temperature" to local tempe = domoticz.utils.round(sensor.temperature,1)

2: even easier:
In the line

Code: Select all

local url = 'http://'..smart_led_ip..'/?message='..tempe..'&static='..static

add your text between message= and '..tempe like for example

Code: Select all

local url = 'http://'..smart_led_ip..'/?message=Hall: '..tempe..'&static='..static

[laco]

Everything works but not rounding.

[laco]

Sorry it works. I had it badly written.

Function code dzVents:

Code: Select all

return {
	on = {
		timer = { 'every 5 minutes'}
	},

	execute = function(domoticz, triggerItem)
	local smart_led_ip = '192.168.1.28' --replace by the ip address of your smart led messenger
	local static = 0 -- change to 0 if you want scrolling text
	
	local sensor = domoticz.devices('Sklenník') -- replace thermometer by the EXACT name of your sensor
    	local tempe = domoticz.utils.round(sensor.temperature,1)
	
	local url = 'http://'..smart_led_ip..'/?message=Sklennik:'..tempe..'°C&static='..static
	domoticz.openURL(url)
	domoticz.openURL('http://'..smart_led_ip..'/?static=1&local=0').afterSec(10)
	-- remove the -- from line above if you want to turn off the screen after 10 seconds
	end
}

It might be good to send data only when the temperature changes.

I need to round the result to an integer.
I get 10.0 on the display and only need 10.
I ask for help.

Code: Select all

return {
	on = {
		timer = { 'every 1 minutes'}
	},
	
	execute = function(domoticz, triggerItem)
	local smart_led_ip = '192.168.1.146' --replace by the ip address of your smart led messenger
	local static = 0 -- change to 0 if you want scrolling text

	local sensor1 = domoticz.devices('Corona nakazení SK')
    	local tempe1 = domoticz.utils.round(sensor1.counter)
	local sensor2 = domoticz.devices('Corona nakazení vo svete')
    	local tempe2 = domoticz.utils.round(sensor2.counter)    	
    	
	
	local url = 'http://'..smart_led_ip..'/?message=Corona-nakazeni-SK:'..tempe1..'_ludi_Corona-SVET:'..tempe2..'_ludi&intensity=1&speed=50&static='..static
	domoticz.openURL(url)
	--domoticz.openURL('http://'..smart_led_ip..'static=0&local=0').afterSec(30)
	-- remove the -- from line above if you want to turn off the screen after 30 seconds
	end
}

Can you try this ?

Code: Select all

return {
    on = {
        timer = { 'every 1 minutes'}
    },
    
    execute = function(domoticz)
        local smart_led_ip = '192.168.1.146' --replace by the ip address of your smart led messenger
        local static = 0 -- change to 0 if you want scrolling text

        local sensor1 = domoticz.devices('Corona nakazení SK')
        local tempe1 = math.floor(sensor1.counter + 0.5)
        local sensor2 = domoticz.devices('Corona nakazení vo svete')
        local tempe2 = math.floor(sensor2.counter + 0.5)

        local url = 'http://'..smart_led_ip..'/?message=Corona-nakazeni-SK:'..tempe1..'_ludi_Corona-SVET:'..tempe2..'_ludi&intensity=1&speed=50&static='..static
        domoticz.openURL(url)
        --domoticz.openURL('http://'..smart_led_ip..'static=0&local=0').afterSec(30)
        -- remove the -- from line above if you want to turn off the screen after 30 seconds
    end
}

Perfect thank you very much.

I added a reading from Custom Sensor, how do I set it up correctly?

Code: Select all

        local sensor3 = domoticz.devices('Dnes nakazený SK')
        local tempe3 = math.floor(sensor3.customsensor + 0.5)

Reporting error

2020-03-26 18:56:00.449 Error: dzVents: Error: (3.0.1) An error occurred when calling event handler Script #9 SLM CORONA

you can do

Code: Select all

        local sensor3 = domoticz.devices('Dnes nakazený SK')
        local tempe3 = math.floor(tonumber(sensor3.rawData[1]) + 0.5)
