sub slave devices

[snellejellep]

I have a question about sub slave devices, the manual said that it was the most difficult and complicated part and that seems to be true so i hope someone over here can help me.

What i want to acomplish:
i have two led strips, for now call them LED_strip1 and LED_strip2. If i turn LED_strip1 on i want LED_strip2 to turn on with it but when i turn on LED_strip2 i do not want LED_strip1 to turn on.
That i accomplished with the sub slave devices and it works fine but there is one problem, If i dim or change the color of LED_strip1 LED_strip2 does not dim or change color als LED_strip1 does, the sub slave device connection does seem to only affect the on/off state. is this normal behavior or am i configuring something wrong?

i hope someone can help me and possibly others.

no one an idea?

afaik is usable only for on/off state...
you will have to use some sort of script (dzvents)

too bad i am not really good at that sort of thing, blockly is what i use and some example lua scripts.
i can read most things in scripts but writing them is a whole other level, respect to those who can!
but if any one has some spare time, feel free to suggest something because i have no idea how i can accomplish that.

wow thanks, i will check that out! and thanks for the comments in the code, maby i can pick up something from that and try it out myself. again, massive thanks!

On / Off and dimLevel is now handled in the script but Color and brightness is a small challenge. What type / subtype are your LED strips ?

i noticed that when i dim it turns off the "slave" and when i dim again it turns back on, i dont know if that is normal or not but i wanted to mention that.

for what led strips i use: the so called master is an philips hue led strip and the slave a yeelight led strip.

if you need more information/tests etc. feel free to ask

[waaren]

Thx for your reply.

I was referring to the type / subtype as displayed in the devices tab.

When I have that info I will play a little bit further with the script and also try to copy the color and brightness Will then also look into your remark that the slave switches off when you dim the master the first time.

[snellejellep]

well i do not have dzvents hardware but these are my devices



i hope this helps you?

[waaren]

@snellejellep,

DzVents weather is just a name of one of my dummy hardware. In use only to define virtual devices.

and yes this is the information I need to continue my little script puzzle. Will get back to you once I have something and tested the different scenarios.

[snellejellep]

@waaren,

i tried the script, it does work fine when i use the switches in domoticz but when i use my hue dimmer switch that i have on the wall it does not seem to react. or is it because i first saved the script, tried it and then realized that there were comments that said i had to remove the checkfirst, which i did afterwards? because i saw in the log that it created a lua script? so maby that is not updated when i update in domoticz? i cant seem to find it in the logs

Please try this updated script. Much obliged if you could report your findings. Master - Slave setup with colors is not completely straight forward as the time the script is triggered the color value is not yet landed in dzVents. So script must be forced to execute a second time.
To do this a couple of vars must be stored in the data section.
I tested with a HUE bulb and a Yeelight bulb and color is following now but still look a bit different.

it now works! wow! thanks! only one small thing is that it does not seem to mirror te color to the second strip? or maby that is because the hue strip is an rgbw strip with two white tone leds in addition to the rgb ones and the yeelight only has the rgb ones. but sill, massive thanks!

[EDIT]
Error was "Error opening url: http://127.0.0.1:8080/json.htm?param=se ... hite=false"
this means dzVents has no access to the domoticz API via a HTTP json call

Solution: SETUP -> SETTINGS -> SYSTEM -> SYSTEM SETUP
[ LOCAL NETWORKS (NO USERNAME / PASSWORD ]

enter (at least) 127.0.0.*

after [APLLY SETTINGS] dzVents will be able to send / receive information to/ from domoticz using HTTP json calls

@waaren
Thanks for your example, just the thing i was looking for but could you maybe explain how to use it?
If i understand it correctly i should make Led_strip2 a slave of Led_strip1, then i add your script as a Lua Device (or All) script or should i add it as a dzVents script and again Device?

Thanks in advance.

[waaren]

If i understand it correctly i should make Led_strip2 a slave of Led_strip1, then i add your script as a Lua Device (or All) script or should i add it as a dzVents script and again Device?

Using this script Led_strip2 will follow state and color of Led_strip1. No need to set anything else as long as the device types / subtypes are the same.
How you add the script using the event editor does not change the behavior of it. That choice does only change the template used in the editor but you should overwrite it completely with this script.
Hope this clarifies.

[schumi2004]

Hi waaren,

Thanks for the feedback.
Eventually i got it running without errors but for some reason the Strip2 did not follow Strip1 although devices are the same.
Maybe it's because of a misconfiguration on my side but i will debug that later tomorrow.

Is it possible to use this also for Ikea Tradfri Bulb's ?

I tried but it returned an error.

2019-04-25 19:56:05.357 Status: dzVents: Error (2.4.18): Ikea GU10 Comp Nis Slave: An error occured when calling event handler Computer NIS Slave
2019-04-25 19:56:05.357 Status: dzVents: Error (2.4.18): Ikea GU10 Comp Nis Slave: ...scripts/dzVents/generated_scripts/Computer NIS Slave.lua:21: attempt to concatenate field 'color' (a nil value)

Is that because Tradfri lights don't actual have a color option?

[waaren]

Is it possible to use this also for Ikea Tradfri Bulb's ?

I am afraid not. I don't own Ikea bulbs but understand they are managed by a plugin.

Is that because Tradfri lights don't actual have a color option?

Yes. The script can only work if both source use the color field. Maybe you can ask the developer of the plugin if this master / slave function can be implemented ?
