Yes, this isn't a problem on my 2012 car -- it turns off by itself.
However it is a problem in model year 2013 and onwards. The OVMS is
supposed to turn off the climate control after a suitable time or
when the car is turned on, but this isn't something I've tested a
lot as I haven't had a chance to make the hands-free microphone work
when the TCU is unplugged on my 2016 car.<br class="">

Thank you! I'll test this out over the weekend.<br class="">

Do you have can bus captures from car with working Nissan Connect?
My car has Nissan Connect but it doesn't work because it was
originally built for Japan and it's now in New Zealand and I don't
have a capture of what Nissan do.<br class=""></div></div></blockquote><div><br class=""></div><div>I have attached a capture from the 2014-model when starting climate control.

I believe you have a 2016 car, and this information is for that
model year? Do you happen to know (or does anyone else know) whether
this is an equivalent for the 2013 through 2015 model years?<br class="">
