Alex, with all due respect you haven't answered my question.
"how does this device overcome the car having control of the FBH?"
I can't understand how you can have control of the FBH and over ride the car, especially when trying to operate the FBH as a park heater.
The popular 1533 timer mod relies on the car being asleep and trips the FBH with a wbus signal.
This mod appears to be based around the same idea of tripping with a wbus signal but as soon as you press the LR button the car will wake up, take control of the FBH and prevent your device from working.
Or have I missed something?  Mods:
Front Fogs + Halos
FBH Remote Control
The 1st Ever RRS Modded Grill
Garmin Nuvi + D4 Surround + Reversing Camera.
D4 Steering Wheel.
Rear Boot Spoiler.
Twin Brake Lights.
Wing Mirror Indicator Repeaters.
Long Roof Rails

You're right, I may avoided the answer as I didn't tested it on a Discovery3. Just on a Freelander2.
As I've said in the previous message, Freelander didn't allow me to activate the FBH until a firmware update. As soon as the new (cold region oriented) firmware was flashed it allowed me to activate the FBH. Still, if you are starting the engine during FBH function, it will stop the FBH. Again, all this on Freelander.
Maybe you should tell me what's happening with the FBH on Disco3 when the car's awake?...
This implementation is working on Freelander2 when you press the light button on the fob and awakes the car. The FBH isn't disturbed and starts OK. I don't think that the firmware implementations are so different on Disco3. Did you tried this on Disco3 and didn't worked?
And even so, in extremis, the idea is how you can build a FBH controller and how you can communicate with the FBH. In other words the missing link between an external command and the FBH. As here are more Disco3 owners  some may try and tell us how it worked.
Maybe VMatas, after he'll start the FBH using this WBus implementation, but with a GSM controller as a starter, will press the Land Rover button and tell us what's happening when you awake the car. If will continue to function, then the problem is solved. If not, then this way of starting, using Land Rover button, may not be viable for Disco3, but the controller will still function with another type of remote acting on the LOWBEAM input.
Like my grandfather used to say, 50% of something is still more than 100% of nothing, isn't it?

I will check on Monday, but my Land Rover button is programmed for boot. Lets see what happened in that configuration.

I'm pretty sure I've started my FBH with the Webasto software on the W line with the car awake, and it kept going.
But I can't be 100% sure. Mark.

Think it depends on what is being used to control the FBH, the 1533 timer will not let the heater run if you wake the car, whilst the BAS controller will keep it running awake until you engage the starter (preprogrammed to cut out at a given voltage drop).

You are sure that 1533 timer stops FBH after car awakening? In what way, if it connects to FBH only via W-bus? W-bus protocol doesn't include such transaction.

I think you have misunderstood. The 1533 doesn't stop the FBH when the car wakens. The car takes control of the FBH and over rides what the timer is doing.
Read my post again at the top of this page or read again Detre's post and just accept the car takes control of the FBH once you wake up the car when using the 1533 timer which also operates on WBus protocol.
This may be different from Freelander but still begs the question how do you overcome the cars ability to take control of the FBH on D3? Mods:
Front Fogs + Halos
FBH Remote Control
The 1st Ever RRS Modded Grill
Garmin Nuvi + D4 Surround + Reversing Camera.

Hi Alex, I did not install the 1533 timer on my car myself so have not looked to hard into it, but from testing with the 1533 timer it does need to be asleep and it need to be less than +5 to start, not so with the BAS controller which controls the FBH via the diagnostic port on the FBH. Maybe the easiest solutions would be to use one of the LR fobs (LR button) standard commands as a command to the BAS controller to start the FBH, if that works, should only require a wire?
For instance if you set your LR Button to open tailgate (might not be the proffered choice ) the same signal could be hard wired to the BAS controller which I Believe has an open input to use with ie a telestart.

Detre, your info is not correct.
My understanding is the 1533 timer forces the FBH to fire up regardless of temperature. The less than 5 degrees rule applies when the car is running the FBH.
The 1533 timer will work so long as the car is asleep.  Mods:
Front Fogs + Halos
FBH Remote Control

Garmin Nuvi + D4 Surround + Reversing Camera.
D4 Steering Wheel.

I'm not sure about 1533 timer, but in my todays experiment Alex controller runs FBH even if i switching ignition ON. If ignition is on, all ECU's are awaked, but FBH operates further and stops only after 15 minutes, as programmed in controller firmware. So there were NO IMPACT from car side, when FBH was started over W-bus. By my opinion, same behavior should be observed with 1533 timer.

My turn to question your logic now, are you certain the FBH continued running and didn't go into the purge cycle when you woke the car?
Can you operate your WBus controller and successfully run the FBH with the car awake? Mods:
Front Fogs + Halos

Yes, im sure that FBH continued run after ignition switching ON for about 8 minutes and only when 15 minutes controller cycle goes out FBH begins switch-off mode.
Regarding second question i will check today at evening.

@ narpy
the fbh from vmatas is NOT connected via can-bus to the vehicle any more
as i understood.
if can-bus disconnected, the fbh runs absolutely independent from vehicle,
i can verify this. i am operating like this since 2 winters. always warm engine
to start, cheaper than change glowplugs...
