Quite a few other manufacturers have done the same thing. I use a reverse engineered Polestar library to get charging status but I'm in the middle of building a CANBUS sniffer to do the same job because I don't trust they won't do the same thing as this.
I don't really understand it, it doesn't seem to offer a huge potential revenue stream and it pisses off the people who are most invested in your product.
Right? I imagine there would be a non-trivial sales/marketing boost for the one/first company (in any segment) to fully embrace HA. IKEA is arguably a good example of this.
This is kind of an interesting contrast with BSH (Bosch and Siemens home appliances ), who are also German.
They appear to have seen making their Home Connect platform open as at least in part a matter of compliance with EU data transparency and portability laws.
The ability to interface with your car is fundamentally at odds with the regulatory momentum that's going towards encrypted everything.
Take a look what the automotive risc-v people are working on or the requirements of the EU cyber resilience act.
John Deere started the trend with locking down the farm equipment they sell.
Is there a repo for the new project?
They already add cryptographic authentication to some CAN messages, so you can't change them. It is only a matter of time until they add encryption.
This is mostly a corporate problem of risk aversion in my opinion. Some department writes down a risk assessment with a list of miniscule risks, for example of some 3rd party app backend being hacked. Or just a headline "Tinkerer hacked his car to use with his home assistant" in the local press. This list circulates, and since nobody in the middle management wants to be responsible for anything, and there is no officially approved positive use case, draconian countermeasures are drafted and constructed one by one.
