Then Miku sold to another company (they either filed or were planning on filing for bankruptcy), and the first thing the new company did was send a letter demanding $10 a month to keep using most of the monitor’s features.
The lesson that it drives home to me is that if a company can force updates to your device, it doesn’t matter what the terms of service are or how much you trust the company.
They can go bankrupt, sell off the assets, and some new vampire company can come along and remove your ability to use your product.
Worse, if your device requires remote services then they can control access to those. Stallman was right.
Our Miku's use a Novelda (fka Xethru) UWB sensor SoC, specifically designed for human presence monitoring and, drumroll, breathing and heartbeat. Specifically they use an X4: https://novelda.com/wp-content/uploads/2023/03/x4_datasheet_...
I likely won't have time, what with the kids and all, but I'm going to give it the old college try to tear into this thing and craft some firmware so we can actually keep things from being a paperweight. It blows my mind this isn't just table stakes with IoT crap these days, but here we are.
In general it’s getting harder and harder to avoid devices where this is possible. The obvious answer is regulation.
