how to change switch-icon on the fly

[BartSr]

I am controlling a light in the garden via an url sent from Domoticz to arduino. e.g.:
http://192.168.2.17/LED=ON and http://192.168.2.17/LED=OFF
Up to now the switch icon immediately turns into yellow-color but I only want to change the switch icon if it's sure the light is on. (Same as with Zwave switches.)

Communication in two ways works already fine for me but it's unclear how to change an icon control.
e.g. set a var named 'LightIsOn' [1=on; 0 I=off]. depending on status of that var the icon should change.

So if the light is on Arduino (in the garden) sents:Domoticz_IP:8080//json.htm?type=command&param=updateuservariable&vname=USERVARIABLENAME&vtype=USERVARIABLETYPE
&vvalue=USERVARIABLEVALUE. A contact of a relay which is connected across the lamp informs Arduino : light is on.

Basically same procedure will be applied later on in the project to show whether or not a gardendoor has been locked (by activation of inductive limit switch). In that case only comm from Arduino towards Domoticz.


Any suggestion?

Hi.
Over 2 years since I asked about changing icons on the fly but never got a suggestion.
Maybe now?

Code: Select all

http://<domoticz ip: domoticz port>/json.htm?type=setused&used=true&name=<name>&description=<description>&idx=<idx>&switchtype=<switchType>&customimage=<iconNumber>

or in a dzVents script:

Code: Select all

domoticz.devices('device name').setIcon('icon number')

Hi Waaren,
Is it possible with this dzVents command to change the Icon 'text' at a custom dummy created device?

Yes but you need to be on the Beta version build >= 12750.
Please note tat the iconchange will only be visible when you reopen the screen or after you manually refresh [(ctrl] r in Chrome) or switch back and forth via another screen.

Great!

Ehh @waaren, how do I find the Icon number? I've got the name but not a number

Maybe there are better / easier ways but I do

Code: Select all

cd <domoticz dir>
sudo sqlite3 -header domoticz.db " select id+100 id ,name from customimages"

to get the to be used number.

Hi Waaren,

Thanks for this info.
I played a bit but for me it seems to academic (syntax).
Would it be possible that you give kind of practic example?

Sure, if you have a dzVents script in where you want to use the setIcon() method and an icon number you uploaded, I will show you how it can be done.

I use it in below dzVents script but because of some of the other techniques used in that code I don't know if it will help or confuse you more.

Dear Waaren, I hoped you might make available an example using the http:/domoticz-ip,domoticz-port etc syntax.
That way It would be possible to change an icon from a device such as esp-easy as well other network devices too. Can you give me a hand on this?
Thanks
Bart

[waltervl]

Why not make a virtual switch instead of a text device? Then you have an on/off icon. If you want to make a custom icon garden lights then you can do that too. No need to do a complicated thing with scripts, just update the device status on/off with the domotica API/json from Arduino.

I already did earlier in this topic.

Dear Waaren. That one I referred to when I spoke about "academic" .
I know once you know how to interprete the syntax it's pretty easy. But the otherway around it might, as for me, have an academic look....

for me this translates to

where MoonPhase is the name of my Sensor (which does not have anything in the description field)
the idx of this Sensor = 164 and is a Generic device type (0)
The customImage number can be found
using

Code: Select all

cd <domoticz dir>
sudo sqlite3 -header domoticz.db " select id+100 id ,name from customimages"

for me this translates to

Waaren, thanks a lot. This makes sense to me. Going to try and will of course revert with results.

..after playing with changing the icons in domotic it helped me a lot..
but I can't figure out how to actually change the icons to on or off. If I write down the numbers assigned to the icons, the group of icons (where there are two icons on and off) has only one number...
