Found this note at the bottom of one of our storage bins in the back of the closet. No clue when it happened, or who it was from. But it made my day.

A subreddit for practical questions about component-level electronic circuits: design, repair, component buying, test gear and tools.
I bought a RPi Zero 2 W and a 7" capacitive-touch LCD screen. It seems the screen is a Waveshare knock-off; I'm not sure. It also seems that a touch screen isn't just a mouse. (Why?!) All that said, the screen (as just a screen) works fine. However, I have no touch ... and no documentation.
I bought . The Waveshare is and . My LCD has no branding or logos whatsoever! Since it seems a "touch screen" isn't "just a mouse," I suppose I need a driver. W/o any docs for the LCD, I don't know where to start. (And from what I've been able to find, all the RPi docs assume you have some "official" LCD.)
Here's a photo of the back of the LCD I bought.
I web searched a bunch on this and nearly everything I find is from 2015-ish; three sites recommend some with a custom driver ... but it's 9 years old!
Anyone have any suggestions?
ESP32 is a series of low cost, low power system on a chip microcontrollers with integrated Wi-Fi and dual-mode Bluetooth. The ESP32 series employs either a Tensilica Xtensa LX6, Xtensa LX7 or a RiscV processor, and both dual-core and single-core variations are available. It includes in-built antenna switches, RF balun, power amplifier, low-noise receive amplifier, filters, and power management modules as well.

I already had InfluxDB and Grafana running on a VM. Wanted to keep some statistics from my nodes there. This will require a spare node connected to a network that you can access and poll. Should be able to use a node connected to a USB, but will need to change the command string.
Uses Meshtastic's python package to get the data from the node. Cron job runs every 5 minutes.
I use Grafana to graph the statistics from InfluxDB.
Sharing in case anyone is interested.
Maybe there is an easier way to do this, but I had fun with the project.
