I have just created an app for the Warmup/MyHeating
Perhaps there are some users who want to test this for me?
It is derived from a github I found (for Home Assistant) and they mentioned the IE4 would work, but perhaps the IE6 as well.

Hi,
I’m using it for IE4. I have 6 thermostats. It looks good, but I found a bug/limitation.
When you change the mode, you can only change between “Program” or “Fixed Temperature”. If you set it to anything else, it will revert back to the previous state after a few seconds.
See screen cam. https://drive.google.com/file/d/1vPL9Yd4Ki3q95sCaUJD4j2pQi9NM1nkL/view?usp=drive_link
Thanks for your effort and support.
Thank you for your feedback, I have updated the app once more.
I made a mistake with the thermostat modes, you only have two, program or fixed.
Next to this I noticed the app crashed during setting the mode, this should be fixed as well.
Power measure is added as well as the device is telling me.
Please note:
Setting the thermostat is based on room, not device. So if you have multiple devices within 1 room, I do not know what is happening.
As for your request about the heater, this is a thermostat with the functions that come with.
As the thermostat does not have a off mode, I am unable to turn it off
Second note:
I notice the API is taking some time before accepting the new settings, so it could lookslike the thermostat is reverting back to the old value, but after 20 seconds or so it is reflecting the correct value.
I am trying to find a solution for this, but for now no luck in this
Sorry for slow response but since last uppdate the behaviour have become weird and i have tried to nail down what it is.
Here is a diagnostic report
fcd15a10-8a0a-432a-9503-16d119aae627
To give one specific example. One thermostat (Master Bedroom) allways goes to 22,5 if mode is set to program. This value does not exist anywhere for this thermostat.

Thanks

Hi again,
one immediate observation.
Warmup should be possible to defined as a heater.
Besides that everything looks fine so far 
Thanks
