check/status broken (with latest firmware?)

[brian-silverman]

I'm running on an HS100, HW version 2.0, FW version 1.5.6 (as reported by Kasa App).

When running, I get an error and invalid result from "check" (my device is actually ON in the test below):

$ ./hs100.sh 192.168.1.25 9999 check
args are 192.168.1.25 9999 check
Connection to 192.168.1.25 9999 port [tcp/*] succeeded!
od: cannot skip past end of combined input
OFF

The reason is that in send_to_plug(), netcat returns nothing even though the payload is send successfully, and od complains about no input. I'm suspecting this broke in later firmware.

Also note: the on/off commands work perfectly. They don't need any output to work, of course.

Thank you for the bug report. I have stopped using the hs100 and thus can't debug and fix the issue in the foreseeable future.

[brian-silverman]

No problem - thanks for the code!

@brian-silverman please pull a new version (from github or docker) and try again, if you find the time. @Beanux was so kind to analyse the issue and provide a fix.

Unfortunately, no, doesn't help in my case (just tried it). I'm not seeing ANY bytes of output from nc, so any changes down the chain (i.e. to egrep) have no effect.
