Where’s The JSON?

So you’re looking at the documentation for an API which was obviously generated with Swagger and you’re wondering how to get the underlying JSON file so you can import it into Postman and leverage it for whatever you’re eager to build.

No worries, it’s fairly straightforward. Simply go into Inspect mode, and search for either swagger.json or openapi.json. (The filename will depend on whether they’re using the older or newer specification, but Postman can import either one– so it doesn’t really matter for your purposes beyond simply finding it.) There will probably be about half-a-dozen references to the JSON file, including one which will give you the details you need to infer the location of the file. From there, you can open it in a new tab, save it, etc.

Alexa and Echo Device Generations

Quick tidbit I discovered while troubleshooting my Echo Dot recently– hope someone else might find it useful.

Have you ever lost track of which generation of Echo Dot you’re working with? 2nd gen, 3rd gen, etc.? The good news is Alexa is savvy enough to tell you which hardware generation you’re talking to, with the simple request of: “Alexa, tell me about this device.”

You’ll wind up with a response along these lines:

Renpho Scale & Google Fit Updates

Old Weight Watchers bio-impendence scale and new replacement Renpho scale, sitting in a cardboard box with lid propped open, juxtaposed on a wooden floor background.

It’s been a significant week in my health/physique transformation goals.

I’d been using an old Weight Watchers scale to track my weight/body fat loss, but began having issues with the bio-impedance functionality failing repeatedly during my weekly weigh-ins. I tried replacing the batteries, but that didn’t seem to successfully resolve the issue. Finally, after a frustrating morning of spending 15 minutes weighing and re-weighing myself just to get any data beyond my total body weight, I’d decided I’d had enough and ordered a replacement scale.

That’s where the “RENPHO Body Fat Scale Smart BMI Scale Digital Bathroom Wireless Weight Scale, Body Composition Analyzer with Smartphone App sync with Bluetooth” (what a mouthful) comes in. It measures more metrics than the older WW scale, uses a combination of Bluetooth connectivity and an Android app to update Google Fit, and the price was around $30 USD (after tax, free shipping).

Although the process of setting up a user account on RENPHO’s site was a little awkward– basically, the initial attempt timed out/failed, but the subsequent attempt told me my account already existed– but everything after that has just worked wonderfully. I’ve used it twice already, and the Android app seamlessly updates Google Fit after you grant it permission to do so once. You open the app on your phone, step on the scale and wait for it to do its bio-impedance scan (don’t do this if you’re pregnant or have implanted medical devices like a pacemaker, by the way) and everything else happens automatically so you can get on with your day.

And speaking of Google Fit, the most recent update adds heart and respiratory rate measurements to its features list. That missing heart rate data in particular was one of the few things which irritated me, but I wasn’t thrilled about dropping $200-300 USD on a watch, ring, what-have-you just to fill in that incomplete data. But with this latest Google Fit update, I just put a fingertip over the camera lens and hold still for less than a minute, and voila! It turns out my resting heart rate is comparable to what it was back in 2003, much to my surprise.
