Compatible with BRC1E73 and FBQ24TBVJU?

[linhpd88]

I am make hardware like mention in this project, try on the FBQ24TBVJU everything work except the temperature set-point.
On the BRC1E73 I can change temperature, but not when send from the module. I can change mode and fan speed too.
I also try both model 10 and 11, it is the same, on this model it also have fan mode auto.
Seem the BRC1E73 is the new one, have anyone try to work with this RC?

extracted_data_all_with_split.csv
This is raw data capture from bus in 20 minutes, include timestamp, I have clean it up with the help of chatgpt, in this log change mode from Cool to Heat, change some temperature and change fan speed.

@Arnold-n can you help me look to this?

Your log does not show any active controller so there is no data to analyze.

I have, but send the raw data if you see any pattern. It reply to 00 f0 30 message, the main RC reply 40 f0 38 message, then it can be control, but not for setpoint temperature. This is the full data when ac
ting as sub rc extracted_p1p2_all_with_split.csv. At the 05:25:59.842 i change the data from 24 to 23 degree but it failed, I change code to retry sending 10 times but still the same. at the 05:26:23.383 I change from Cool to Dry and it work

The problem is that your T version has different messages lengths for the 00F039/00F03A packets than the (closest?) model 11, so the reply length for the 40F039/40F03A is likely not correct. You may have to change the P1P2Monitor code and experiment with which length to use for these replies, and which byte to change in the reply packets to get the remaining functions working.

I have try both model 10 and 11, with 18/20 message size but it not work, also try toggle c0/e0 back and forth without any luck, note that change mode, fan speed, power on/off work, but not the temperature setpoint. I don't clearly understand what you mean, 00f039 and 00f03a not relate to control? now the payload for 00F03A is 8 zero payload and for 00F039 is 5 zero (model 11 in your code)

I changed my remark a bit to clarify/correct my remark. Given that the messages for 00F039 and 00F03A are not the same length as for model 10 or model 11, we do not know for sure if we use the right answer length for 40F038 - 40F03A and we do not know if the right location (and reply method) in the 40F038 message is used. Though it's strange that temp setpoint does not work while the others do. This may require some further trial-and-error to see how the temp setpoint can be changed.

Reply method for 40F038 was corrected because mode, power, fan speed was changed, but it may wrong position for setpoint. I was try to change some position but no success. May be the length is not correct. But the package length of the 00f038 is the same with model 10 or 11. The BRC1E73 also support many AC include FXMQ (model 11) https://www.yanmarenergysystems.com/webres/File/SPEC-BRC1E73_Navigation-Remote-Controller-III.pdf, I don't know why they change package for FBQ24T
