Okay, yeah, that is definitely concerning.

There are no ads on my Kindle.

After the feature of being able to send EPUB files to Kindle through email and them being automatically converted… I have not felt I was missing anything by using standard Kindle software.

So I’d suggest, unless you really really need some obscure feature, Calibre+Kindle is nowadays perfectly fine, and maybe you shouldn’t risk bricking your device.

This thingie fails miserably when trying to listen to covers, alternate versions and the like. Most times it just plays a different version. And I hate that.

It depends, but I’d say you should definitely try it. Zigbee is so cheap (not just initial cost, but batteries also last waaasy longer and it doesn’t saturate your local network), and it’s very possible you can still build a nice mesh, maybe reusing a couple of your Wi-Fi switches somewhere else in the house if you need a Zigbee router in one of those spots.

It was never the best idea to fill your home with tiny Wi-Fi devices. Wi-Fi IoT devices are more for people who basically want to automate a couple of things, not 40. I would become mad just for the battery changes, and scared as heck I’d be toasting my brain with so many devices screaming radiowaves (and a clear slowdown of my Internet connection).

True Mexican food from an actual restaurant. For your health.
