I’m studying cybersecurity with a focus on software development/appsec but hardware hacking is just a hobby

Hello. Local guy here (SL county). I am very impressed with your work. I have done similar on a ford through canbus and simulated button presses based on i2c temp sensors read at startup. and just purchased a 21 rav4 hybrid. It looks like you've done all the work :) I am wondering if you are able to get the temperature of the cabin from the linbus? Then either go "max heat", "max cool" or do nothing based on received temperature. BTW I found this today, so I am still going through it all. Thanks for posting your work.

@Maximize0987 thanks!!

Unfortunately I can't, it doesn't seem like the car sends that data on the climate panel bus. It's probably on canbus somewhere, but I'm not sure which message it would be in.

yes I had a lot of difficulty figuring out what I did with my ford's canbus, and could not find the cabin temp from it, so I used temp sensors for that input. maybe I'll pick your brain, if I have question when I 'm working on my solution. Thanks.
