If you depend on a third party to handle your IoT device you just own a pricy brick. They can stop at any time, they can change what is supported, they can change the price. It won't change as there is no money in making devices we can run under local control.

@thomastraynor not just “smart home devices” anymore either. I was shopping for an elliptical machine last night and most now come with something called iFit.

The majority of the features on the marketing page are iFit features and only work if you subscribe to the $40/mo plan. I had to dig and dig to find what one of these machines would be capable of if you don’t associate it to one of these subscription services.

In the end I bought from a non-iFit manufacturer 🤷🏻‍♂️
