Heating / 240v Inverter - how long does "Ready" mode last?

I bought an ex-demo Peugeot e-Traveller Allure in October and intend to put in a modular kitchen / storage / fold out bed utilising the original rear two seats. I'd hoped to use the HVAC system to maintain the temperature whilst camping, and the integrated 120W inverter was an added bonus though I hope to run an small induction hob so a separate inverter and / or battery storage would be required.

Due to various medical emergencies / work / Christmas I haven't been able to spend as much time looking at this as I'd like to, but it appears that the car disconnects the HV battery when in park for a (relatively) short period of time - around 10 minutes. On two occasions it lasted longer, first time was 1 hr 30 minutes when I started at 91% SOC, in ECO mode, in park, with no A/C but charging a laptop on 240v. Second time was 45 minutes when started at 83% SOC, in normal mode, in park with heating set to 18 degrees C, and a load on 240v inverter - in both these occasions, I only stopped the timer as I had to leave the car and do other things. When I tried again below 60% SOC, it only lasted 9 minutes or so, and I've been unable to replicate the previous results so I'm unable to say with certainty under what circumstances the HVAC system will run longer.

I'm slightly disappointed that ECO mode completely stops all heating, whereas on previous EVs I've owned it would only limit the performance. The dashboard gauge for the HVAC only seems to show either full (but not in the red zone) or off (ECO zone) - altering the fan speed, temperatures, or A/C doesn't make a difference other than indicating on or off. Lastly, the range guessometer also seems to be very sensitive, particularly in the tests above using HVAC whilst not travelling - with the range dropping dramatically, even if I then went to drive very economically.

Anyone bought a PSA group van or MPV with camping in mind? I assume there will be similar issues for the Spacetourer, Zafira Life since they are so closely related - don't know if there may be any firmware updates to resolve this (and if they'd be distributed to all models across the group) or a workaround... I already considered remote pre-conditioning but its a limited length of time, and doesn't enable 240v inverter (so I don't know if the DC-DC converter would top up the 12v battery if I used a separate inverter).

Any thoughts or experiences would be appreciated.

You can keep ”ready” mode on indefinetly if you put something heavy on brake pedal. This keeps the car from turning off heating etc.
ECO mode keeps only fan turning, no heating or AC.
HVAC power gauge is pointless, basically shows that heating uses power but does not shownhow much.
My personal body-brick i.e. foot on the brake pedal definitely stops the HV battery switching off. I'd read about just leaving the driver seatbelt attached and in park (I also tried neutral with handbrake on) but this didn't work.

So... what we need is something to make the brake sensor appear to be activated, but also to switch off the brake lights AND the DLR. I imagine this might be possible, but not easy...
Yeah, this is definately doable but not easy. You will need 6 relays. Peugeot uses 4 wire brake pedal sensor, when 2 contacts close, other two open. So 2 relays to brake pedal and two for DLR as they are independet of each other and two for rear lights.
No need, I have upgraded my front lights and while I was doing it, I occasionally had only one light connected. No warning/error messages on dash at first, but after 5-15min it showed a warning to ”check lights”.
Warning disappeared right after reconnecting the light. So in a way this would be a good warning to remind you that brake pedal/lights disconnect is still active.
