It may be worth buying and using an accessory telematics module through a data gathering corporate server with an annual service subscription in order to Remote Start an out of key fob range vehicle (close its HVB contactors for the PTC heater or air conditioner compressor), particularly if the LFP battery temperature regularly drops much below freezing. If the manual HVAC knobs are preset correctly, that can condition the cab. The hope of the OP and some others in this thread is that the app will have settings that bypass the knobs’ physical settings, getting them out of sync. I don’t think so, but we’ll see.

A Slate app must at least duplicate the fob—door lock and unlock, pop the frunk, and remote start. In the other direction, it should show at least battery State of Charge (SoC) percentage, Guess-O-Meter (GOM) miles remaining, Charge Rate/Status and hopefully Charge Time Remaining Estimate if charging, Doors and Frunk Lock Status, as well as confirmation of commands sent to the vehicle, including Remote Start Status. For fleet use, telematics will also continuously transmit location, speed, and direction to the server for tracking. It will consume LVB energy when the vehicle is off but will likely reduce the frequency of cellular GPS updates to save energy.

I don’t see the need for Slate to try to replicate Apple or Google Maps or ABRP if it can give them battery SoC and temperature as well as access to turn on battery preconditioning.

This is what I believe the bottom of the app home page looks like with GOM but not SoC, and buttons for audio and energy. I wouldn’t be surprised if there was a graphic of the fob above it with buttons (but probably not). Perhaps someone has a better photo of it.

This kind of falls into the "be careful what you wish for" category. We wanted simple, we got simple; now we gotta live with it.
^ This.

I guess I read into this too deeply. I remember the time when the air distribution selector was full on mechanical and that slide selector actually pulled a cable to engage the distribution flaps under the dash. Sometimes it was hard to select. And sometimes it wouldn’t stay put when driving and you had to keep correcting it.
So yes expecting these knobs are fully electronic that are articulating a servo to make those distribution and temp selections. Cost and reliability should be there now without added cost.
Its pure gravy if they are remotely controlled but highly doubtful as that = expense.

This by far is the best HVAC control design ever introduced by any auto maker. BMW E30:

Except thats a rendering, not an actual photo, so theres no guarantee that it ever even existed like that in any physical realm. Id trust that about as well as I trust Amazon reviews. Maybe a bit more actually....but only a bit. 😅

Our 2019 Forester’s third (dash top) display has an optional GOM page I’ve never used. I don’t care about my MPG or how many miles it thinks I have remaining. With $1/gallon Kroger fuel points discount, I don’t even look at gas prices. All I want is the fuel gauge and all I want from an EV is State of Charge. If I’m lucky to get that from an EV automaker it’s usually a smaller font than miles remaining which I’d love to be able to turn off.

I just realized heat has a button to turn it on and off just like AC, that's actually pretty helpful.
Should help with windshield defrosting AC+heat+windshild vent position.

Try this. Works on anything with an OBD2 port (so basically everything). Then you can design whatever layout of any data points the car can provide to be displayed on your phone or tablet or laptop in a variety of themes. It even has limited programming capabilities (depends on the car manufacturer and any addon software you might buy).

Ive had one for years and love it. Ive bought several for family and car buddies. Its saved me sooo many hours of diagnostics and repair costs its paid for itself many many times over, even when factoring in I'M the one doing the labor! And thats counting the add ons Ive bought and the 3rd party programs Ive bought that can use it, too.

The OBDLink MX+ uses only standard Bluetooth (Bluetooth 3.0/Classic) whereas the “A Better Route Planner“ (ABRP) app requires a dongle that supports Bluetooth Low Energy (BLE),
