3d printer octoprint domoticz monitoring

[DAVIZINHO]

finally im trying to configure MQTT in domoticz
now i need to create the node-red flow. im in progres!!!

edit:
I install MQTT and node. but im very lost with this.
Im really noobs with this and i dont know how to create the node flow and link the octoprint plugin (mqtt) to send the info to node and domoticz
some help?
thanksssss

EDIT2:
works! this not so easy but fine

@DAVIZINHO
I did describe exactly how to paste in the node flow - maybe you didn't read this... anyway I will then post the link:
viewtopic.php?f=21&t=14021#p162935my guide?

yes I read but only apears the "orange box" not the others.
This was the first time i use node, maybe my fault but like I said, i can solve the problem and now it works perfect!
thanks

Hello,
I've made a lua script to get data from Octoprint through the API.
It's still a work in progress and when the printer is off you will have errors in Domoticz logs.
But I will try to improve it later.
if anyone want to work on it, please do.

I've updated the script, so now when the printer is turn off, no error is throw.
Same when printer is turn on but not currently printing.

Whow, thanks, looks like it works good, except for one thing. Only when I shutdown Octoprint (the whole raspberryPi) I get the following error in the domoticz log:

2019-12-10 23:34:06.437 Error: EventSystem: in /home/pi/domoticz/scripts/lua/script_time_octoprint.lua: /home/pi/domoticz/scripts/lua/script_time_octoprint.lua:58: attempt to index global 'JsonOctoTemp' (a nil value)

I tried the Event editor in Domoticz, and also just the plain scipt in the script folder, both gave the same error.

That's strange, I have no error on my side.
Are you sure you are running the lastest version ?

When my printer is off, I only have this in Domoticz logs :

Do you have the Json.lua in the right place:
json = (loadfile "/home/pi/domoticz/scripts/lua/JSON.lua")() ?

Yes I copied the code from the Github, And I do have the JSON.lua in the right folder. All data is coming in Domoticz fine, but I only get this message when I shutdown octprint. I've got Domoticz V4.10717

[chatainsim]

Ok, I've misreading it.
It's when you shutdown Octoprint not the printer.

So I need to fix this.

I've updated the script, it should be fixed now.
Keep me posted, Thanks

Great I'll give it a try, Thank you!

The error message is indead gone, Now I only get this one:

EventSystem: Warning!, lua script octoprint has been running for more than 10 seconds

I've added a timeout to ping command, maybe this willl help.
Can you try ? Thanks

Sorry didn't work, I get a message every hour:
2019-12-15 10:00:12.994 Error: EventSystem: Warning!, lua script octoprint has been running for more than 10 seconds
2019-12-15 11:00:10.287 Error: EventSystem: Warning!, lua script octoprint has been running for more than 10 seconds
2019-12-15 12:00:10.127 Error: EventSystem: Warning!, lua script octoprint has been running for more than 10 seconds

This is when Octoprint is offline (so the Pi is completely off)

EDIT

:
I see the script is triggerd every minute, next to that it spams my log, don't know if thats bad?

Hi, i just want let you see what i made untill to now.
Switching the printer on and off does not require a plugin. I put a Sonoff POW between the power cord. The sonoff is flashed with Tasmota.
I switch the printer on with it and i can follow up on the power use. Then i created a Domoticz keep alive on the Octoprint IP address. In the keep alive switch i put the off command for the sonoff.
When Domoticz now sees that the Octoprint is not responding it will send a poweroff signal to the sonoff.

[Yokohama]

For monitoring Octoprint i use Node Red. First you have to add the MQTT plugin to Octoprint.
In Node Red i use the following flow:

Octoprint.png (61.65 KiB) Viewed 3352 times

I still haven't figured out how to put the time estmates in it but this works mutch better than the Lue script i used before. The script made Domoticz unstable (timeouts).
The Node Red code is below, please enhance and correct if you want.

I have been working on this, this should be better.
But there is still room for improvement.

In the beta version, there is now an Ocotoprint hardware.

I can see the Octoprint hardware made it into 2021.1 but I can't see any documentation about it, is anyone using it?

It has options for settings in\out topics but that doesn't actually appear to flow to anything as I can see in the MQTT logs it still publishes on the default OctoPrint/, it looks like it doesn't do any discovery and there is no option to create a virtual device for it, do we need to create another hardware device and create dummy devices to feed into it?

Thanks
Wob

interesting.... I just came across this thread, didn't even know, that this interface exists.
I may need another RPI for my 3D printer then.....
