Unable to communicate with the HS110 plug anymore

[Hir0-84]

Even a simple command to get the system info:

python tplink_smartplug.py -t 192.168.1.2 -p 9999 -j 'info'

returns "Cound not connect to host 192.168.1.2.:9999".

Recently I have installed the new firmware update v. 1.5.6 for the HS110 2.0 model. Could that be the reason?

I have also noticed that recently you have pushed a commit giving the possibility to pass a different port number. Did TPLink change the port? Btw, I have tested the latest version of the script and I still get the same error message.

Can anyone reproduce the problem? Can it be that TpLink has changed teh port number or the key?

[Hir0-84]

Sorry again guys! I have rebooted the router and I could access again the smartplug. I managed to send only one shutdown command successfully but not a second time. The plug returns again: "Cound not connect to host 192.168.1.2.:9999".

Does anyone experience the same problem or my plug goes in conflict with another application that uses the port 9999? Is there a way to tell the plug to listen on a different port?

I have the same issue.
Last year it worked fine, maybe it was the fw update?

i tried now over udp with the tppd-client wihtout success.
I think, tp-link changed quite a bit in the last firmeware.

Quite annoying that tp-link does not offer any support for automatisation.

@Hir0-84 just out of curiosity: why did you make the firmware upgrade in the first place?

personally I didn't know there was a nice exploit like this, and anyway, there is a big button named update firmware it makes you want to press it.

but it was a good lesson

Haven't tried this myself but there are instructions for local upgrade online, so these just might work for a downgrade too.

Of course the new firmware might specifically check for a downgrade and prevent it.
