Telnet debug
If you experience issues it can be useful to run a debug to see what is going on "under the hood".
So this is how you run a Telnet debug:
First, update the firmware to last version. It is recommended store the current configuration first (use System/Configuration file menu, or just make screenshots of the various pages).
Then run telnet debug as follows:
- Go to System/Debugging, turn on Telnet debugger, Debug level "Verbose" and press Save:
- Go to Configuration/Wifi and note which IP address your device is using.
- If needed: Enable Telnet on your PC by following this method: https://social.technet.microsoft.com/wiki/contents/articles/38433.windows-10-enabling-telnet-client.aspx
- Open a "Command prompt" window on your computer
- Write Telnet <IP-address>
Example: My Pow-K has IP-address 10.0.0.6:
- You should now see the payloads in hex format as they arrive from the meter. If all is well it will be something like this, but it depends on the meter and the format coming from your meter.:
- If there are issues with interpreting the data, there should be understandable information here.
- When you are finished it is recommended to turn off Telnet debugging (System/Debugging)
A bit more details
For those of you not familiar with using command windows, a customer has been so kind as to provide the following (in Norwegian, assuming others can be able to follow it too):
*** Åpne terminal vindu i en mappe som du vil ha som midlertidig "path" til Telnet log fila.
Windows:
* I filutforsker: "Mus" over mappen du vil ha, så 'Shift + høyre klikk' og les i popup menyen.
* Har du åpnet mappen i filutforsker, skriv "cmd" i "folder path" i toppen.
TIPS: For å justere vindus bredde, høyre klikk på øvre ramme > Egenskaper > Oppsett
Linux:
* I File Manager: "Mus" over eller marker mappen du vil ha som "path", så 'Shift + høyre klikk' og les i popup menyen
----------
*** Copy text in cmd ***
Right Click (les i "pop up"), Mark , Left Click & drag to mark , Enter to Copy
----------
** HUSK: i teminal MÅ du bruke høyre klikk ved "paste" **
* Start telnet I terminal vindu skriv: telnet
*
Tilordne log fil: set logfile telnet.txt (telnet.txt = din log fil ,
har du brukt metoden over trenger du ikke å bry deg om "path")
* Start logging: open 192.168.10.201 (IP addr for din AMS Reader)
* Stop logging: q (+ Enter)
* Exit Telnet: q (+ Enter)
** Resultatet blir da slik:
telnet
Velkommen til Microsoft Telnet-klient
Escape-tegn er CTRL+¨
Microsoft Telnet> set logfile telnet_1.txt
Loggfil : telnet.txt

Microsoft Telnet> open 192.168.10.201

Trykk en tast for å fortsette... NB !!!!

Har du brukt "set logfile telnet.txt" slapp av, da er dataene der. Men du må avslutte Telnet for å kunne lese fila.
