Unexpected Restart of Flow an Venus OS

[usauerbrey]

I am running NodeRed_Heishamon_control on a Raspi 3+ under Venus OS. The Flow restarts every 5-10 min, lately after 30 min, but the log does not help. Is there any known problem with Venus OS or could it be too less memory (TOP does no say so) or do you have any other idea how do fix this.

Thanks Uwe

I do not know Venus OS. I have no experience running this on a raspbery pi 3. I can not comment on the hardware requirements for this.

How much RAM does the pi3 have?

[usauerbrey]

The Raspi has 1GB, TOP says: Mem: 609444K used, 334836K free, 1980K shrd, 37428K buff, 74920K cached CPU: 43% usr 8% sys 0% nic 44% idle 0% io 2% irq 0% sirq Load average: 3.23 3.23 2.63 4/311 15404

[edterbak]

It should be sufficient. I gave my container 2GB, but it is only using <400MB

Do you see error messages in the debug screen? What messages do you see in the log?

[edterbak]

What version of node red is being used?

[usauerbrey]

Node Red: 3.0.2 the log says: 24/06 15:58:12 - Function - WAR: 0 24/06 15:58:02 - Function SoftStart: SoftStart function end 24/06 15:58:02 - Compressor: stopped 24/06 15:58:02 - Function Pump speed: Max pumpspeed set to undefined (NaN%) (Low) 24/06 15:58:01 - SYSTEM: MQTT block inactive, default block mode: BLOCK ALL 24/06 15:57:58 - SYSTEM: WAR settings OK 24/06 15:57:58 - SETUP - Sensors: Custom room temperature sensor not found.

Where do I find th debug screen?

[usauerbrey]

Or do you mean the debug of Node-red?

[usauerbrey]

The next restart was at 24/06 17:15:22 - SYSTEM: Start--------------------------------------------------------------- and the debug of node red shows: 24.6.2023, 17:12:57node: Function - bucket 1 + 2 combined function : (error) "TypeError: Cannot read property 'payload' of undefined" 24.6.2023, 17:15:25node: System check function : (error) "TypeError: Cannot read property 'on_off_active' of undefined" 24.6.2023, 17:15:26node: Function - bucket 1 + 2 combined function : (error) "TypeError: Cannot read property 'payload' of undefined" 24.6.2023, 17:15:27node: Load trigger function : (error) "TypeError: Cannot read property 'PumpMaxFlowSetting' of undefined" 24.6.2023, 17:15:28node: Draw chart function : (error) "TypeError: Cannot read property 'detection_method' of undefined" 24.6.2023, 17:15:29node: Draw chart function : (error) "TypeError: Cannot read property 'detection_method' of undefined" 24.6.2023, 17:15:30node: Function RTC automation function : (error) "TypeError: Cannot read property 'function_active_state' of undefined" 24.6.2023, 17:15:31node: Draw chart function : (error) "TypeError: Cannot read property 'detection_method' of undefined" 24.6.2023, 17:16:24node: 2148ba5e64e1066d msg : error "Error: A 400 Bad Request error occurred: {"error":"unable to parse 'electricity,location=COP cop=NaN': invalid number"}↵" 24.6.2023, 17:16:25node: 2148ba5e64e1066d msg : error "Error: A 400 Bad Request error occurred: {"error":"unable to parse 'electricity,location=COP cop=NaN': invalid number"}↵" 24.6.2023, 17:16:25node: 2148ba5e64e1066d msg : error "Error: A 400 Bad Request error occurred: {"error":"unable to parse 'electricity,location=COP cop=NaN': invalid number"}↵" 24.6.2023, 17:16:25node: 2148ba5e64e1066d msg : error "Error: A 400 Bad Request error occurred: {"error":"unable to parse 'electricity,location=COP cop=NaN': invalid number"}↵" 24.6.2023, 17:16:25node: Draw chart function : (error) "TypeError: Cannot read property 'detection_method' of undefined" 24.6.2023, 17:16:25node: DHW SP Manager function : (error) "TypeError: Cannot read property 'state' of undefined" 24.6.2023, 17:16:25node: Function RTC automation function : (error) "TypeError: Cannot read property 'function_active_state' of undefined" 24.6.2023, 17:16:25node: Function RTC automation function : (error) "TypeError: Cannot read property 'function_active_state' of undefined" 24.6.2023, 17:16:25node: cee35b0a1e2da0ea function : (error) "TypeError: Cannot read property 'function_active_state' of undefined"

Function Pump speed: Max pumpspeed set to undefined (NaN%) (Low)

This one is good to know. thanks. I think the startup process for people with fresh setups needs to be checked if all is handled nicely. I will do that.

Question. Have you setup correctly the persistant storage?

I would like to advice you to go into every tab of the functions and set values and toggles manually. WAR tab. Pumpspeed RTC COOL Softstart Solar2DHW

Start with all functions disabled.

[usauerbrey]

Have you setup correctly the persistant storage? I am not sure. I tried to do it like you installation hinta say, but it doent not work. If I set softstart = ON, it is OFF again after a restart.

[edterbak]

I suspect the persistant storage is one problem. (it might not be the only one)

You have to figure out how to change the settings.js for Node Red. Make sure the contextStorage is working correct.

[edterbak]

Look into a [change] node. You need to see this "file" in the dropdown. If you do, it is good. If you dont... this needs your love :)

[usauerbrey]

indeed at least one of my problems is the persistant storage. I found 11 files named settings.js in the system and 3 of them contained a section contextStorage. I change all 3 files to the correct content of contextStorage and rebooted the system. Nevertheless the check with the change node fails. I will investigate

[edterbak]

Did you get this sorted?

[usauerbrey]

Hi Ed Sorrily not. I could not manage it to enable persistence storage in the Venus OS based Raspi system. So currently I am out of ideas. Best Regards Uwe

[edterbak]

The raspberrys are getting back in stock.prices are lowering again. You could pick up one and set it up with ssd drive as os disk. Or if you have (like me) a home server, setup proxmox and run a linux system virtually. Or if you have a NAS you might be able to run a docker container with a linux and setup node red in there.

Sorry to hear the venus os thing did not workout yet. Is there a support page for users for it?

[usauerbrey]

Of course another Raspi ist a solution, but I am not very happy with it. I am going to make an own flow, which is very limited and does not use any persistence data at all. The graphs I need are genereated via graphana (on a different system on a different site anyhow)

[edterbak]

Good. Dont let yourself be stoppen by something like this. Just do it yourself. :) This is the power of mqtt and the heishamon. Hope you get things as you want it soon.
