Timer led turned on

[mortenmathiasen]

I can make my Panasonic CS-HE9JKE model react on requests made by this fine heatpump library. However, it starts blinking the Timer led for a few min. When timer led turns of the heatpump starts swinging vertical and horisontial without much fan or heat production. What happens? Can I overcome this problem somehow or reaction working as designed by the library?

It should not work that way... The problem is that I don't have access to HExJKE-series, but just assumed it works based on the feedback from others. Is there any chance you could build in IR receiver using an IR receiver module + any Arduino board? This way we could record samples from the real remote, and compare against what the library sends.

[mortenmathiasen]

Yes, I can record the remote signals next time I travel to my vacation house where the heatpump and its remote are located. I could record the signals by http://zmote.io/ but I suspect that you prefer the signals recorded by https://github.com/ToniA/Raw-IR-decoder-for-Arduino ?

[mortenmathiasen]

Now I got recorded the remotes signals. I chose to record all actions except setting the timer. The resulting report is available here. How do we proceed from here?

[mortenmathiasen]

I have now adjusted the library and made the Arduino send IR-signal similar to the original Heatpump remote. For a test I have recorded the signals sent from both two devices.

My setup is MySensors based and you find my Arduino sketch at MySensors.ino

Signals from the two devices are equal, but the heatpump starts blinking with error H11 when signal comes from the Arduino. Any suggestions on how to solve this problem?

[ToniA]

I'm quite puzzled... The Panasonic protocol ha snot changed much since the DKE series, and I haven't heard of issues like this. Like you state, the signals look identical, the timings are very much the same, and still you get a different result.

H11 (Indoor/Outdoor Abnormal Communication) sounds very strange, I mean as a result of receiving an infrared command.

[mortenmathiasen]

I agree that the error is strange. In addition, signals from the Arduino have a short recognition distance. Right now, my best guess is that the problem is a timing issue. Hence, I consider to check the timings, e.g. by using IRLib2 - would that be your suggestion too?

[ToniA]

The short distance could be because of timings, or if the frequency is a bit off. At least on ESP8266 I understood using a bit more accurate send method gives a better range.

[mortenmathiasen]

Now, I have used IRLib2 to compare the timings of the IR signals from original remote and arduino:
