Be able to disable or relocate '/data/node-red-contrib-home-assistant-websocket.json'

[bjornstevens]

Hi there,

In my case I use node-red as a Energy monitoring system for Home Assistant. I am a very happy user of this integration but I did notice something very annoying; the amount of writes.

While looking pretty much everywhere I found out that the 'node-red-contrib-home-assistant-websocket.json' file was doing these writes. In my situation I have around 8 values being updated nearly every second, causing the data also to be written to that file every half a second ( ~4 every 0.5 sec).

Is there a way to relocate this file/ turn it off completely?

Thanks,
Bjorn

(do notice in the picture, it ain't the size of the file, it's just the amount of writes!)

I'm assuming you're using the entity node. It was saving the payload on each input even if resend wasn't checked. I changed it to only save when resend is checked. So if that was what was causing all your disk writes it was changed in the latest release.

Hi, Thanks for the reply!

What does the resend mean/do?

Btw, also a funny backstory:

My SSD had an insane amount of writes, here is the difference between the disks where node-red is on VS a SSD with VM's:

Node-red had a lot of writes comming in per second. In total I would guess around 10 per second. In total that would make it 864.000 writes per day 😆. This fix litterally saves my SSD's lives lol.
