How to send sequential MQTT commands?

[877]

Hi everyone,

I am controlling a Hue bulb via MQTT, please see the image for example commands. I would like to be able to sequentially send commands, with a time interval in-between.

Example requirement 1:
Change colour to red
Send breathe effect
Change colour back to original

Example requirement 2:
Send blink effect
Change brightness to 0%
Timer for 25mins
Set brightness to 100%

Currently I am able to achieve example 2 with two trigger nodes, but I'm thinking there's a better way.

Example flow and image:

You could have commands in an array and use split node to send individual commands, with possible delays between each.
e.g.

[{"id":"d6ef1d4f.d3bbb","type":"inject","z":"5a245aa1.510164","name":"Brightness 128 (0-254)","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload":"[\"{\\\"state\\\": \\\"ON\\\", \\\"color\\\": {\\\"r\\\":255,\\\"g\\\":0,\\\"b\\\":0}}\",\"{\\\"effect\\\": \\\"blink\\\"}\",\"{\\\"state\\\": \\\"ON\\\", \\\"color\\\": {\\\"r\\\":255,\\\"g\\\":255,\\\"b\\\":255}}\"]","payloadType":"json","x":200,"y":2960,"wires":[["e4c3c2c8.f3c9d8"]]},{"id":"e4c3c2c8.f3c9d8","type":"split","z":"5a245aa1.510164","name":"","splt":"\\n","spltType":"str","arraySplt":1,"arraySpltType":"len","stream":false,"addname":"","x":400,"y":2960,"wires":[["771df0dd.4182f"]]},{"id":"771df0dd.4182f","type":"debug","z":"5a245aa1.510164","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"true","targetType":"full","statusVal":"","statusType":"auto","x":550,"y":2960,"wires":[]}]

You could have a lookup table of commands and just send the keys to create the commands array on the fly if you wished. You could also do all this in a function node, using node.send().

If the intervals are fixed then you could send them all at once and pass that through a Delay node in Rate Limit mode.

@E1cid @Colin thanks both, between the two suggestions I already have a better solution!

[Paul-Reed]

@877

I already have a better solution!

Are you going to share it?
It may help others reading this topic.

[877]

I see how my wording was not clear, I should have typed, ....now I have a better solution. I was referring to the solution in the earlier comments....

I always like to share the solution, normally I find my own posts many months later!
Here is the flow combining the two recommendations:
