Can you insert this line just before line 136 ? It should show the value of type.

Code: Select all

dz.log('type: ' .. tostring(type),dz.LOG_FORCE)

i put the command on line 133. but i think i made a mistake.
I think the problem was in the notification. must be set in the sensor and not in the Alert

[mojso]

how to enter this command: if PM10 is greater than 50 and less than 100 changes the light color to yellow

How to make a light-color switch from the value obtained from the device

What is the name, type , subtype hardware of the colorLight ? (look at the devices tab)
Can you please describe the complete value - color mapping (e.g. 0 - grey, < 50 - Green, < 100 Yellow, etc..)

name : desk light , type : Arilux AL-LC0x , subtape: rgbwz

0 to 50 green
50 to 100 yellow
101 to 150 orange
151 to 200 Red
201 to 300 purple
301 > Maroon or purple-blinks

[waaren]

301 > Maroon

Can you try this. (not completely tested yet) and no blinks as I have no clue how to set that.

maybe the colors in the Hex/RGB color code will solve this

[waaren]

maybe the colors in the Hex/RGB color code will solve this

No, that will not help. Your device does not support the setRGB method. Can you replace line 72 with these lines

Code: Select all

-- device.setRGB(control.red,control.green,control.blue)
device.dump()

and send me (via PM) the complete resulting log (> 100 lines). It will not change colors but will help me understand why this device does not support the setRGB method yet.

Hi,

Do you know that a Domoticz plugin for air quality exists?

See: https://openaq.org
Plugin: https://github.com/Xorfor/Domoticz-OpenAQ-Plugin

It's easier than inventing the wheel twice.
If you are in The Netherlands you can also use the script in this thread:
https://www.domoticz.com/forum/viewtopic.php?t=17334

Regards.

Thanks. Didn't know about the plugin from Xorfor. Makes life much easier. [strike]Do you happen to know how often this plugin updates?[/strike]. Found it, once about every 60 minutes. Which is fine.

Hi, I have a question again, the script works great, but I can not see the data from the previous year or it is not saved at all, how can I make it look at the data (report link in other sensors)

Hi, @mojso

It is not available. Also many other sensors are not available.

Regards

Hi, I have a question again, the script works great, but I can not see the data from the previous year or it is not saved at all, how can I make it look at the data (report link in other sensors)

That functionality is not implemented for custom sensors. Data is available in database in table multimeter_calendar but if you need a multiyear report you will have to export the data from the database to something like excel.

Code: Select all

cd <domoticz dir>
sudo sqqlite3 domoticz.db
.mode csv
.out report.csv
select * from multimeter_calendar where devicerowid = <device id>;
.quit

[mojso]

thanks Waaren for the reply. I do not want to export the data for now, just have a preview in domoticz (Report link) thanks in advance

thanks Waaren for the reply. I do not want to export the data for now, just have a preview in domoticz (Report link) thanks in advance

I don't think it will be implemented for custom sensors any time soon; if at all.

I use only the PM10 status.

                    else
                        dz.log('No sensor for: ' .. tostring(type),dz.LOG_FORCE)
                    end

I think the log is better now:

Hello,

I'm also experiencing log errors on air quality. in fact, it's flooding the log quite considerably.

2021-10-07 11:00:10.049 Error: dzVents: Error: (3.0.2) An error occurred when calling event handler Air Quality
2021-10-07 11:00:10.049 Error: dzVents: Error: (3.0.2) ...moticz/scripts/dzVents/generated_scripts/Air Quality.lua:51: attempt to index a nil value (field 'pm25')

When i manually enter the url in the browser, i do get information for pm25. maybe the api changed a bit, but i really am not good enough a programmer to troubleshoot this. it used to work, and i don't quite know when it stopped...

Any pointer where i should start searching for clues towards a solution?

thanks
Willem
