High cpu % usage with this node

[MattL0]

Hi,

all my nodered, npm, node.js, debian etc are updated to their latest stable release.

I created 11 nodes (alexa devices) with you plugin/package.

Today i was looking at htop and ...i saw node-red cpu usage is more or less constant to 50% usage. ( I have a amd 2700x cpu).

So, this is the only change in nodes i made to my node-red setup in the last days.
I tried to clean the cache of npm... but it doe nothing.

One thing I try is copy paste the flows i created with your npm package, then i removed them...and i deployed node-red. Since then.. my cpu usage is back to normal (0-5%).
Finally I putted the flows i just remove into node-red ... and deployed again.. ( had to rediscover with ALexa but this is normal). Unfortunatly, node-red process is back to 50% again.

I will send you my two flows in another message

So this is the first flow. I use those nodes to triggers events ( same as scene if you want) of my Homeseer automation system ( an example in homeseer would be...: when an specific mqtt message receive a payload with ''on'' then turn on the event ''goodnight''

So this is the second flow. I use those nodes to directly ( by mqtt) associate the value receives in the payload to a specific node in my Homeseer HS3 system. I needed to write a function for some of those to work, because they are dimming node in my Homeseer setup .

I think i know when the issue happen ( with dimming lights)

1. When i say alexa light to 25% ''
2. Alexa light off
   3: alexa light on.

then the node-red process goes directly to 50%
