Q: neopixel color change based on relays (lights) in vera

[rchamp]

Hi there, i created a very crude sensor that connected to a strip of neopixels. i have it simply fade to white when the light is pressed on and fade to black (off) when pressed off in vera.

However, i've tried to now create some more "relays" as switches to allow me to trigger different light effects/modes, but i don't know how to create a switch, or case to check "when relay 1 on, color mode 1, relay2 on color 2, etc" It always reads a general 1 or 0, regardless of which light send the command from vera.

Any ideas on how i can change the code in the receive function to listen to each switch(relay) and then trigger a different condition from there?

below is my code

I have a RGBW node that also have mode selection and I send the mode from Vera to the node using V_VAR1.

This is maybe not what you are looking for but maybe it can give you some idea or be helpful someway.

@korttoma

thsnk you for the input. how does the interface look in vera? I'm not too clear on using the V_var options. I do like doing this through a single sensor vs trying to use different.

I think my biggest problem right now is understanding how to write the code to understand the differences of the messages coming in from vera/the myS gateway

[korttoma]

I actually do not have anything in the interface for setting the mode. I just use a simple lua command:

luup.call_action("urn:upnp-arduino-cc:serviceId:arduino1", "SendCommand", {radioId="11;3", variableId="VAR_1", value=1}, 24)
