Support for Truma Caravan A/C devices

[laserir]

Here are some IRrecvDumpV3 (v2.7.13) dumps for the Truma Aventa Caravan A/C devices. Let me know if the captured data are sufficient for integration of the protocol.

The only options with this devices are:

• Temperature in °C (16-31), only available in AUTO or COOL mode
• Mode (AUTO,FAN,COOL)
• Fan (LOW,MEDIUM,HIGH), only available in FAN or COOL mode

[crankyoldgit]

Here are some IRrecvDumpV3 (v2.7.13) dumps

Can you please try the current version of the library (v2.7.16) to see if the protocol has support already added?

[crankyoldgit]

I've added experimental support for this protocol in branch: https://github.com/crankyoldgit/IRremoteESP8266/tree/Truma_basic

The bit ordering/representation may be subject to change, as the data you've supplied is not enough to be sure yet.
I need a full temperature range capture, as per: https://github.com/crankyoldgit/IRremoteESP8266/wiki/Adding-support-for-a-new-AC-protocol#determining-the-bit-order-of-the-protocol to work out if I've got it correct or not.

It should however be enough for you to test sending and basic decoding of codes, just the values may be subject to change once we are more sure of the format.

Please download, test, and give me feedback etc.

[crankyoldgit]

Oh, and please provide detail model numbers/brands etc of the A/C unit and the remote.

[laserir]

The manufacturer is "Truma", the model range is called "Aventa" the remote works for the "Aventa compact plus", "Aventa compact" and "Aventa comfort" models. (https://www.truma.com/de/de/produkte/truma-klimaanlagen) The remote is model/part no "40091-86700". Most likely the remote is the same as for the discontinued "Saphire" model range, but I cannot confirm for sure.

I will come back with complete captures as of your link.

v2.7.16 didn't decode the signals. For the new branch I'll have to try.

[laserir]

EDIT: Online version of spreadsheet in post below
Attached the captures, hope this will do?

[crankyoldgit]

@laserir Can you please convert your spreadsheet to a publicly readable Google Spreadsheet (or similar service) for those a don't have Excel etc, and it is also updated live, rather than you having to upload a new sheet for each change, and for people needed to download the whole thing for each change etc.

As the decoder should be working in that branch (Truma_basic), it should be producing 56bit hex values (e.g. 0x45ffffffe8da81), please provide those rather than the rawData[] ones. Only supply those if it doesn't match as TRUMA. I tested it with one of the rawData codes in your sheet, and it decoded fine.

[laserir]

Done! Here are the captures:
https://docs.google.com/spreadsheets/d/1k-RHu0vSIB6IweiTZSa3Rxy3Z_qPUtqwcqot8uXVO6I/edit?usp=sharing

Let me know if you need anything else.
