What do you use for furnace/AC monitoring? Do you get data directly from the equipment, or just infer it from environmental trends? I assume the power data comes from embedded monitoring facilities in your UPS? What make/model do you have? I have a similar setup in my house, but it’s lacking a few metrics. Monitoring air quality (CO2, particulates, etc) would be nice, and my local electric provider sounds a lot like yours, so voltage monitoring would be great.

As noted elsewhere in the thread, they do support MTP transport, so it’s definitely not as user-hostile as it first sounded. Things like Calibre will still work. However, the fact that Amazon also removed the ability to download ebooks in the browser for offline transfer suggests where things are heading. IIRC kobos have some anti features of their own, but I don’t recall the details. I wonder if something like the Daylight DC-1 could be even better. It’s not just a nice reader, but a proper computer. At least, if it actually exists.

I’ve owned two Kindle devices over the years, and the ability to directly load content, without involving a third-party service, was a big part of what made them usable for me. If that feature is gone, these devices will no longer be viable for my needs.

And the enshittification continues…
