Node-RED: Sending multiple commands to dimmer

[rakeshg]

I have recently added a dimmer (Ultrapro) and I wanted to always set the level to 25% when it is turned on (in case someone messes with the level manually). Currently I am doing this in two steps - msg.command = on and then a device node with setLevel hardcoded to 25.

Q1: Is there a way to send both commands at the same time?
Q2: What would be the correct syntax for msg.command if I wanted to set the level in the flow (not hardcoded in the device node). Would it be msg.command = setLevel,25?

Thanks for your help

I have a couple of those and don't send an On.. just the setlevel. If it's non-zero, that's the level it goes to. "On" is implied. I understand that there are brands that don't behave like this. I don't have any and would return them if I found I had gotten one

Thanks for the tip - let me try that.

That seemed to work but only when I hardcoded it in the device node. I was using msg.command = setLevel, 25. I also tried msg.command=setLevel;25. Thoughts?
There is also an odd "flashing" behavior when it turns on/off - not sure what that is about.

Works for me. The Above is an experiment. The OFF node is hardcoded.

The dimmer node has no Arguments, but hints at the format.

The two Change nodes set two different levels like that.

It could have been "24, 30" to have a 30 second ramp.

msg.command = setLevel, 25. I also tried msg.command=setLevel;25.

msg.command = setLevel
msg.arguments = 25

msg.command is a string.
msg.arguments is a number, but the hubitat nodes are forgiving, so you want to specify a ramp time, you can make it a string (like "25,30")

You can have a single change node in which you set both msg.command and msg.arguments.

Thanks so much @csteele and @aaiyar. I’ve used msg.command and msg.arguements before but completely forgot the syntax!
