I use it. But I am retired and do not drive every day. It gets disabled 12 hours after the last use of the car, so some days I find the overheat protection is not working, and the app shows my interior temps rising up as high as 120F.

Somewhere I saw one concern with Cabin Overheat Protection is that it cycles the A/C and causes moisture built-up and this can lead to mildew, etc. People suggested fan-only mode to prevent that. It would be nice the the software running the A/C did things to prevent issues, but I don't think it does yet.

Is it true car alarm and of course sentry have to be off?
I used to use it until I read stories of compressor failures on older Model S’s. Using cabin overheat protection will significantly increase the use of the vehicle’s compressor, which may shorten its life. The cost of replacement is in the thousands.
Other EVs also use electric compressors. Some of the Tesla expense has to do with a bad compressor also hosing the DC/DC converter. I guess when it fails it draws too much current and fry's the additional components (speculation). That part is also not cheap. Replacing a compressor is an ICE is expensive and can also run thousands. This is not a problem unique to Tesla. I think replacing my cell phone battery early is preferable to potentially replacing my compressor.That sounds like a legitimate concern. Any idea why the compressor is so costly? I wonder if it is because it is custom made for Tesla so it is a low volume product. Do other cars use electric AC compressors? Seems as if at least other EVs would, but do any ICE cars use electric compressors or are they all still belt driven off the engine?

In the help right where you activate it it says alarm must be off. This is why I am asking. I saw temp going to 44 Celsius in my car and it won't kick in.Cabin overheat protection works fine for me with the car alarm turned on. I haven't tried it with sentry mode to see if it still works.

It is very dumb that the alarm has to be off...Yep - I read that in the help and tested to see if it works... it does for me (at least it did before my most recent software update... I guess I'll try it again).
Is there a setting to allow just fan to circulate air in vs running the AC compressor, when overheat protection is on?
On the compressor load.
Is periodic low load cycling worse than blasting full bore to cool the car quickly once you precool or start driving?
