[APP][Pro] Simple (Sys) LOG - Use this app for Simple (Sys) Logging

[Steve_Nye]

I thought it was working as my log file was created fine, however when I came to run in earnest and looked at the content it is lots of fairly random characters.

If I look at the LOG tag as got, by hovering over the tag, it looks fine. If I save as another variable it looks fine so I guess it is something to do with the file and only difference I can see is that your card shows a folder symbol, whilst mine doesn’t.

I reinstalled the app a while ago, hoping it would eliminate the crashing I experienced before. Unfortunately, it didnt.

Here is a log of event, it seems there is a pattern. (Every night at three o’clock, I clear the log older than 20 days). It looks like it takes a bit longer to do the cleaning every day, until after three days it can’t do it anymore (for whatever reason) and crashes.

Any suggestions? Thanks in advance!

@Steve_Nye

your card shows a folder symbol, whilst mine doesn’t.

You should be able to browse to the target folder, one folder deep at a time, by tapping into the [Directory] placeholder, something like:

If not, check the login or connectivity, by going to the device tile of the NAS, and starting the repair function, to view the folders, and check if you can view or enter a folder

.

@Steve_Nye

the content it is lots of fairly random characters.

Yeah now it’s the same overhere. No clue what’s going on, I even saved it to 2 other storage systems, but only using this card solves it, Steve:

Thank you, that now works perfectly.

Hello, thank you for this fantastic application which I use daily. I’m encountering a problem: when exporting (to Excel only), the application crashes and nothing is exported. Here is my diagnostic report.

Thank you for your help.

How big is your log? My experience is that exports of large logs can be problematic. As a work-around I clear my log every month, after having made an export of that month.

@Kameomanu

Here is my diagnostic report.

You have an Out Of Memory error (one that I have never seen before btw, very strange).

But OOM means the log is larger than homey can handle to convert or read at once.

@Steve_Nye

difference I can see is that your card shows a folder symbol, whilst mine doesn’t.

Which Save flowcard are you using?

Save Text or Save Base64?

You need to use the Save Text (bottom) flowcard for csv.

Is there a way to not show syslog message on the timeliness? I want severity messages from a certain level to be logged but not in my timeline… Couldn’t find this option:

[Arie_J_Godschalk]

Yes. You are now using the flowcard which specifically include: write tot timeline.

Use the flowcards without that specification:

[Wout_van_den_Dool]

Oooooops open door, I was seeking for settings etc etc​

[Oyvind_Lilleberg]

Really like this app and are currently working implementing automate cards and log cards in my flows from the API script.

I have som questions then:

1. Is it possible to specify what Severity the log shall be entered under. For now you can only make global change in the flow for all the trigger/condition/action cards. Say I want the log from a condition card to enter as “debug”, and another log from a condition card to enter as “info”. Is it possible?
2. I want a little easier access to the log without going through all the steps to open the settings app inside the Homey app. Can I export the log to somewhere it is a bit easier to look at? Maybe a widget in the home screen in the Homey app. Just like the bulit in Timeline in Homey. And then maybe filter out just the logs classified as error er debug?

HTML page ready! Here you can check Syslog on the fly (while at home). Just change the Homey IP address in the URL… Save this code to a HTML file and save on eg. your Home screen on you phone. <!DOCTYPE html> <html> <head> <style> table, th, td { border: solid 1px #ddd; border-collapse: collapse; padding: 2px 3px; text-align: left; } th { font-weight:bold; } </style> </head> <body> …

I’m still very happy with this app and the message center I built around it:

[APP][Pro] Simple (Sys) LOG - Use this app for Simple (Sys) Logging

Thanks @Rrrr @Peter_Kawa and @Arie_J_Godschalk your post inspired me to re-assess my messaging setup, based on Simple Log… I am currently simplifying all my flows in terms of Messages… And it looks like this (taken into account Severity level) Advanced Flow based on Simple Log [image] Severity levels and Device to send message to: [image] Synology Log Center [image] Default card used in all Flows [image]

However, my Homey Pro now runs ~230 devices , so I’m trying to move some heavier apps to my Homey Self-Hosted Server .

A good example is WhatsApp. I actually only use it in one flow: sending notifications from my message center. Ideally I would move the WhatsApp app to the server to free memory on the Pro (±100 MB).

The challenge is that a device running on Homey Server cannot be used directly inside an Advanced Flow on Homey Pro .

So I’m thinking about the following setup:

1. Replace the WhatsApp card on Homey Pro with a Simple Log client entry
2. Send that message to a Simple Log server running on Homey Self-Hosted
3. Trigger a flow on the server that forwards the message to WhatsApp

This would let me remove WhatsApp from the Pro while keeping the same notification flows.

Two questions for the community:

• Does this architecture make sense? And how to do this?
• Has anyone already used Simple Log as a cross-Homey message bus like this?

Curious to hear thoughts or better approaches.
