The TRMNL is an 800×600, 1-bit e-ink show linked to a battery and a microcontroller, all housed in a pleasant however unremarkable plastic case. Because the microcontroller spends the overwhelming majority of the time sleeping, and BloodVitals device since e-ink displays don't require power until they're updating, the battery can final six or extra months. It charges over USB-C. When the microcontroller wakes up, it connects to a Wi-Fi community and communicates with a pre-configured server to fetch an 800×600 picture to display, and the duration of the next sleep. You may flash your personal firmware on the device, or level the standard firmware at a customized server. The corporate offers an example server, BloodVitals device although you may implement the (HTTP-based mostly) protocol in whatever means you would like. I considered operating my own server, but thought I might give the straightforward path a strive first to see if it might suffice. The default service lets you cut up the display into a number of tiles, blood oxygen monitor and there are a lot of pre-constructed and group-constructed things that can show in each.
None of them labored nicely for me, however that's okay because you'll be able to create your individual private ones. They get information both by polling a given URL, or by having data posted to a webhook. The format is rendered using the Liquid templating system, which I had not used earlier than, but it is reasonably straightforward.

With a 3D-printed holder, super glue, and a few magnets, it's now happily caught to the fridge the place it displays the current date and the household occasions for the next week. Probably the most awkward a part of the default service is managing the refreshes. The system has a sleep schedule, and so do the tiles, BloodVitals device that are solely up to date periodically. So the mixture can easily depart the incorrect day displaying.
It can be helpful if the service instructed you when the machine would subsequent replace, and when a given tile would subsequent update. But it isn't an enormous deal and, after slightly bit of head scratching, I managed to configure things such that the device updates within the early hours of the morning and BloodVitals SPO2 the tiles are ready for it. The price has gone up a bit since I ordered one, BloodVitals device and BloodVitals device it's a must to pay an extra $20 for the Developer Edition to do attention-grabbing things with it.

But CGMs have been both costly and prescription-only. And I'm not a diabetic, kind 1 or in any other case.

So CGM know-how is now out there to the mildly curious, like me.
