RGB dimmer devices access to build in states

2 issues:

1.====
for RGB dimmer devices brightness seems to either 0 or 100, nothing in-between.
in the sdk is also no example on how to set this,
how is is calculated. just 0 or 100 for on/off?


2.===
the building devise stated eg redLevel can be set withe dev.updateStates ...()
but i am not able to read them:

tried

Code: Select all

 if "redState in dev.states .. is False

Code: Select all

xx = dev.states["redLevel"] throws error

Code: Select all

dev.redLevel shows None

doing indigo.log( unicode(dev) ) shows

...
batteryLevel : None
blueLevel : None
brightness : 0
redLevel : None
...

although they do show a value in the detailed device pane


======
And finally a python question:
how do I access dev.ppp
with ppp a variable = "redLevel" / "greenLevel" / "address"... (dev.redLevel works but shows None)
shows error: 'DimmerDevice' object has no attribute 'ppp'


Karl

it seems the devices was not properly initialized -- the properties supportXXX was not set .

BUT still the 2 questions remain:

== for RGB dimmer devices brightness seems to either 0 or 100, nothing in-between.

Karl

as for the python question:

This works,

Code: Select all

xxx="redLevel"
exec("aa = dev."+xxx)
indigo.server.log("returned: "+ aa)

but there must be a pythonic way

Karl

[jay (support)]

Code: Select all

xxx="redLevel"
value = getattr(dev, xxx)

ok thanks,

and the brightness value =0 or 100, nothing in-between?

Some more questions on brightnessLevel (not brightness)

The attached:

Screen Shot 2020-03-01 at 11.04.32.png (15.1 KiB) Viewed 1906 times

shows a dimer device w prop SupportsOnState True, SupportsWhite True
I am updating state: "brightnessLevel", the number in the slider is correct, the position of the slider is NOT as well as the Brightness number on the right
setting state "onState" to False sets brightness to 0 as well as the slider - and the other way around

I here a setting I am not aware of, or how should:

Code: Select all

"SupportsColor"
"SupportsRGB"
"SupportsWhite"
"SupportsWhiteTemperature",
"SupportsRGBandWhiteSimultaneously"
"SupportsTwoWhiteLevels",
"SupportsTwoWhiteLevelsSimultaneously"
"SupportsOnState"
"SupportsSensorValue"
"SupportsStatusRequest"
"AllowOnStateChange"


be set to for
1. a simple dimmer
2. a dimmer with white color / temp
3. a dimer w RGB only
4. dimmer w RGB & W & temp

The RGB Color devices support overall brightness as well as individual R, G, B (and up to 2 white channels) levels to specify the color. The Example Device - Relay and Dimmer plugin in the SDK has the best documentation on all of the properties and their dependencies:

Code: Select all

SupportsColor:                                  True or False
-> SupportsRGB:                                 True or False (requires SupportsColor to be True)
-> SupportsWhite:                               True or False (requires SupportsColor to be True)
      -> SupportsTwoWhiteLevels:                True or False (requires SupportsWhite to be True)
      -> SupportsTwoWhiteLevelsSimultaneously:  True or False (requires SupportsTwoWhiteLevels to be True)
      -> SupportsWhiteTemperature:              True or False (requires SupportsWhite to be True)
      -> SupportsRGBandWhiteSimultaneously:     True or False (requires SupportsRGB and SupportsWhite to be True)

So note SupporsColor needs to be set to True for any of the other properties to be used.

I red all of that, that is clear..

after some more testing it seems to be:
when "onOffState" is used brightness only follow sTHAT state, not brightnessLevel
with property SupportsOnState off and no use of updateStateonserver("onOffState"..) the brightness works fine

I'm having a hard time following what you mean. Can you walk me through a specific example and the results?

when "SupportsOnState" is true
brightness follows dev.udatestateOnServer("stateonOffState" ,true/false)

[matt (support)]

What do you mean by "follows?" Can you give me a specific example, with values?

If you are wanting the On command to go to the last known brightness (before it transitioned to the OFF state) then see this thread.

In dev edit / props: "SupportsOnState" is true

dev.updatestateOnServer("onOffState" ,True) ==> brightness=100
dev.updatestateOnServer("onOffState" ,False) ==> brightness =0

dev.updatestateOnServer("brightnessLevel" ,50) does not change brightness

Karl

[matt (support)]

Did you try changing dev.onBrightensToLast as shown that other thread?

However, I don't see how that would fix this:

dev.updatestateOnServer("brightnessLevel" ,50) does not change brightness

I don't know how / why that would fail. That should always set the brightness if it is a dimmer instance. No error logged in the Event Log?

no errors in log

and what does dev.onBrightensToLast do?
its not in the dimmer example

anyway I am happy now.. do not use SupportsOnState for dimmers then everything works -- for me

Karl

[matt (support)]

I suggest you try:

Code: Select all

dev = indigo.devices[123]
dev.onBrightensToLast = True
dev.replaceOnServer()

I don't understand why changing SupportsOnState would change the behavior (no doubt it does, but from looking at the code it is a mystery). Regardless, the instance does support the on/off state so you should leave it set to True. Note it is set to True by default for all relay and dimmer instances when it is created. I think the root problem here is probably that we should be defaulting dev.onBrightensToLast to True for new instances but we aren't and you need to explicitly do it yourself.
