Itach Remote - Works at first then nothing

1

Hi all,
I am having issues with my iTach Remote component and wanted to see if anyone else had similar problems and had found a solution. I have a simple script that sends an IR command to my TV to turn it on, waits a few seconds and then sends an IR command to tell the TV which input source to operate with.

After I restart HA, I test the script and it works perfectly!!
However if I run the script again without a restart, it sometimes doesn’t work, maybe works once, maybe several times, and eventually stops working…In all cases when its not working no IR is being sent out to the TV. I also verified with wireshark that no IR command is being sent out to the GC100.
Again if I restart HA, I test the script and it works perfectly!!

Strange. I have two iTach Flex Ethernet to IR units and they have been faultless.

What does your script and remote code look like?

I should have added, that when things stop working, its not just the script that stops working.
Even the simple flipping of the “Remote On/Off” switch does not work (no IR output).
With Wireshark running, there is no packet being sent to the GC100, so there is something
broken on the HA side. My guess at the moment is the itachip2ir C++ library, but its just a guess.

As I said, It’s working perfectly for me so this is unlikely to be the case.

I was able to setup the logs to capture things…
Case working:

Case Not Working:

The difference being, the C++ library (pyitachip2ir) in the failed case does not call its socket for sending data to the GC100.
Unfortunately the logs don’t reveal why.

I’ll just go with the Remote code to keep things simple since it also doesn’t work.

I figured out the problem way back when, and just now getting around to posting the solution as someone else recently has run into similar issues.

See here:

along with instructions.

Nice solution. Any chance it could be merged with the core component?
