Node-red gives double update bug.

[Malosa]

FOR NOW SOLVED WITH A WORKARROUND
https://flows.nodered.org/node/node-...ntrib-throttle







Hi guys,

Well since i checked my influxdb i did see double value's all the time after a status and value gets updated by 1 device.

I have a virtual device in homeseer that updates now and then together the value's (status and Value)
So when it updates and i check the output in node-red it triggers 2x, 1 time for status and one time for value in a second..

is there a way to get rid of it?
It kinda messes up my database now.


its setup for testing like this:
HOMESEERDEVICE ----> DebugWindow msg.payload.


regards

Can you uncheck the Node's (HS Device) status reporting back to Node-RED

Or you may need to include RBE node in your setup.

Hi Eman,

well i did try what you said, i added the RBE event and set it up like this (block unless value changes - payload.status)
For now it works, so value and status have both same value.

But i don't think i can trust on that..

What i don;t understand, all plugins in homeseer what update status and value at same time do not trigger double...

Does it have something to do how i build my scripts to update the value and string data ?



this way is what i have in all my scripts to update the data:

Dim Ref
Ref = hs.GetDeviceRef("PWR-YDAY-GAS")
hs.SetDeviceValueByRef(Ref, data True)
hs.SetDeviceString (Ref,data, True)

If you are interested in values only remove the string
And also you have string only as well

You can have a device with value and string or one of each




Note: You can use a switch node to filter out the conditions that suit you and then when condition reach the change node, this is where it doesn't matter what's coming in, you can mold it to your heart's desire.

Tip : Always include a screenshot people can quickly understand you better.

hi thanks,

but the thing is why it works with plugin devices ?
And with scripts it does not work at all..

The problem i use all the info that is in msg.payload

I just want to get rid of the double triggering all the time.
I need status and value, aswell all the other info.

the RBE does work, but it will only update only one of them instead of them both, so i have 2 different value's in influxdb.

For me it now looks Node-Red triggers faster than homeseer changes value

Malosa ,

This could be the case but until you show people your setup it's hard to blindly follow up but from what I can guess, do you have Graphana In HomeSeer?

If so can you separate it and move it to the Node-RED side (I never played with this but it seems a good guide : https://www.hackster.io/naresh-krish...grafana-8960d3)

• So if you have a similar project then you would have branch off nodes which report into HomeSeer HS Device nodes reflecting that data of which you would want triggers in HomeSeer.

ksum or someone could help you with is node : https://flows.nodered.org/node/node-...trib-msg-speed and the Delay node : https://www.hardill.me.uk/wordpress/...ly-pause-node/




How is that?

[Malosa]

here is my screenshot


the devices are virtual and triggered from my script, you see it triggers 2x because the value takes 1ms longer to update and sometimes status

But when i change that device to a homeseer plugin device for example (plugwise plugin with the device name p1 total), it triggers 1x with status and value) and the status and value are updated the same in homeseer.. so no delay.



See plugin device, it works normal

[Eman]

On this latest post you could use some switch nodes like mentioned earlier to split the incoming messages before the change nodes.

Thanks, look the new last screenshot, that works normal if using device from a plugin


Could you show me a example how i can manage that?
i don't know how to.. i did try many times but won't work
if i change the type of payload structure, it won't be imported to influxdb, i'm using homeseer default payload.

this is my flow

OK,
I have moved away from my desktop but at my post #5 there are 2 links that I posted. They're are a good explanation of how to use a switch node as a filter. They will help you in what information you want to pass through by separating status from values so you put RBE nodes on each. So there neither is blocked before they each fire again.

In other words "Status" gets its own nodes and so does "value"

Dim Ref
Ref = hs.GetDeviceRef("PWR-YDAY-GAS")
hs.SetDeviceValueByRef(Ref, data True)
hs.SetDeviceString (Ref,data, True)

The difference is that most plugins do not update the device's string explicitly, they only set the device value which automatically update the device status unless the device's string is not empty.
For example if your device has a range of [0; 100], and you set the device value to 30, the status of the device will be automatically set to "30" at the same time.

thats true,

but its just weird that devices updated from my script gives a 1ms delay on value/string in node-red that causes a double payload.
and the plugin-devices from plugwise they update string and value same time after change.. so its not different than my script does.
but node-red get an delay when triggered by script, and by plugin no delay at all..

I have found a thing that helps me out for now.
u can set it up that it will only trigger every second message in 2 seconds

https://flows.nodered.org/node/node-...-timed-counter

and it works good for now, i will test it out till HST has fixed the issue.

Many thanks for the help Eman

[Eman]

Cool!

There is also the Throttle contrib which can limit passing messages to once every X seconds. So setting it to 10 seconds means it only passes a message once every 10 seconds.
